|Anime debut||Yu-Gi-Oh! VRAINS episode 1: "My Name Is Playmaker"|
Kolter, known as Shoichi Kusanagi (
Kolter is a young man with fair skin and grey eyes. His purple hair comes to the base of his neck, and it has multiple small bangs brushed over to hide his forehead, and he also sports a small goatee. Kolter dresses simply, wearing a brown trench coat over a purple hoodie with a bronze zipper and light blue shirt, and teal pants tucked into burgundy boots with prominent black soles.
Kolter is a rather friendly individual. He's shown to be sympathetic towards Yusaku and hopes he can one day enjoy Dueling again. He also regrets dragging him into the fight against the Knights of Hanoi.
Behind his friendly easy-going nature, Kolter harbors an intense anger and hatred towards the Hanoi Project just like Yusaku, though he doesn't actively show it unless triggered enough, like when he listened to Akira Zaizen talk about the possibility of Aoi being kidnapped. Kolter angrily said that Akira doesn't truly know what the horrible trauma he felt was like.
Being the owner of a food truck, Kolter is a capable cook; he was seen cooking hotdogs.
Like Yusaku, he's a talented hacker. He was able to get information about SOL Technologies' activities and helped Yusaku capture Ai in the latter's Duel Disk. He was also able to figure out that Aoi Zaizen is "Blue Angel". On several occasions, he has hacked surveillance camera's in both LINK VRAINS and the real world alike with little effort. He is noted to routinely erase footage, article, and picture of Playmaker in the network.
Ten years ago, Kolter's younger brother was kidnapped for the Hanoi Project in the past. Even though his brother was rescued, he still suffered intense PTSD that he apparently never recovered from, prompting Kolter and Yusaku to fight against the Knights of Hanoi, whom they believed to be responsible for the incident, to get revenge.
Kolter and Yusaku discussed SOL Technologies and Hanoi's recent movements. Kolter told Yusaku about the Data Storm and that it could help Yusaku enjoy Dueling again. He also mentioned SOL was looking for an AI on the run and that they were planning a full scan of LINK VRAINS to find it. Hearing this, Yusaku came up with a plan to capture the AI and use it as a trump card against Hanoi and closed Café Nagi, despite Kolter protesting that he was expecting customers that night. The two hackers managed to capture Ai into Yusaku's Duel Disk during an attack from the Knights of Hanoi. Kolter was surprised when a Data Storm occurred when "Playmaker" challenged a knight. He was worried when Yusaku was sucked into a Data Storm tornado, and was relieved when Yusaku won the Duel.
Kolter and Yusaku spent the next few days trying to figure out Ai's programming, but Kolter struggled to understand the complicated algorithms that Ai was made out of. He then suggested to come up with a name for the A.I., to which Yusaku decided to name it "Ai", a pun on "eye". He was also impressed that the card data Yusaku obtained from the Data Storm was becoming a physical card. Trying to scan footage from "Ai's" memories caused the Knights of Hanoi's leader to track them down, however Kolter shut down Café Nagi's power before they were found. The next day Kolter gave Yusaku the "Decode Talker" card that had finished materializing before he went to LINk VRAINS to fight a supposed Knight of Hanoi that appeared. When the Knight turned out to be Gore, a program that prevents Playmaker from logging out was activated by SOL Technology. Kolter worked on an escape route for Yusaku, but Yusaku refused to use it. After the Duel ended, Kolter scolded Yusaku for not using the escape route, but also suggested that they could recruit Gore for their fight against Hanoi.
Kolter discovered that the real identity of the famous idol "Blue Angel" is Aoi Zaizen, a classmate of Yusaku. He thought about Yusaku meeting Aoi so they could get closer to Akira Zaizen in order to get more information about SOL Technologies regarding his brother and Yusaku's memories, however he also doubted the plan would work because of Yusaku's poor social skills. A few days later, he was shocked when Playmaker and Blue Angel began a Duel before getting interrupted by a customer.
After the Duel concluded and Aoi was put in a coma, Kolter hacked into the hospital's records to find out about Aoi's condition. Ai protested that hacking into the hospital was a crime, to which Kolter casually said that hacking already was a crime in the first place. Ai explained that Aoi had been infected by a virus from Hanoi's card and the only ones with the anti-virus were Hanoi themselves. "Blue Angel" appeared claiming that she wanted a rematch against Playmaker. Kolter knew right away that she was an impostor and instructed Yusaku to ignore her because it was clearly a trap, but Yusaku went into LINK VRAINS anyways because he felt it was his responsibility to save Aoi. Varis's appearance and subsequent manipulation of LINK VRAINS caused Kolter's cameras to go offline, though he was briefly able to use SOL's cameras and later Ghost Girl's. He was displeased when Ghost Girl's camera stopped recording, making him unable to watch anything inside LINK VRAINS. To watch the Duel, Kolter used the bugs in the Knights of Hanoi's program that created the Data Storm to open a path for Ghost Girl to enter the Data Storm; she had her cameras record the Duel between Playmaker and Varis, allowing Kolter to watch it.
Kolter was glad that Playmaker won against Varis and carried him after he logged out since the former took a lot of strain during his Duel. Since Yusaku was interested what became of Aoi, Kolter went to show she was recovering. Yusaku fell asleep and Ai commented how lazy he was, but Kolter claimed heroes needed to rest. Ai started bragging, so Kolter went to analyze what kind of program he ate from Varis. Realizing Kolter would look into his "private parts", Ai called him a pervert and refused to say anything. Once Yusaku woke up, Kolter sensed he was thinking what Varis told about Ai. Since they did not know how to prove if Ai was actually alive, Ai claimed it, indeed, was alive. Ai used the program he obtained from Varis to recover his body back. However, Ai's size didn't impress Yusaku and Kolter, who tried to analyze if Ai regained some of his memories, even if Ai wanted them to be excited that he regained his body.
A few days later Emma Bessho ran into Café Nagi, but neither she nor Kolter recognized the other as "Ghost Girl" or "Playmaker's assistant". Emma ordered a coffee and two chilli dogs and mentioned she was interested in Dueling Playmaker, causing Kolter to wonder what kind of Duelist she is. Yusaku noted that Kolter looked exhausted, to which Kolter said that he was tired from spening all night deleting "Playmaker" files and videos that people constantly post on the network. Yusaku offered to help him with the clean up, and in doing so he inadvertently deleted a big scoop that would've revealed everything Playmaker and Kolter know involving Ai and the Knights of Hanoi.
During the night, Kolter called Yusaku to come to his food truck and showed him an encrypted message on an internet forum, sent to him from Ghost Girl. Kolter explained he had created a program to navigate her to enter the Data Storm during the Duel with Varis. The two read how she demanded a Duel from Playmaker, with Ai as wager. Yusaku accepted, stating that she offered a backdoor to SOL Technologies' data bank, and Kolter confirmed that fact, showing she did send a bit of the data as proof. Yusaku asked of Kolter to reply that Playmaker would accept her challenge. Ghost Girl soon entered LINK VRAINS, and Yusaku went to do the same. Kolter wondered if Yusaku would really go and Duel her, since she could've set another trap. Yusaku claimed he had to uncover the truth behind the incident, hoped in the data bank there was some information about Knights of Hanoi, and sensed some determination in Ghost Girl, despite her weaknesses. Kolter watched as Ghost Girl and Playmaker confronted each other, and wished of the latter to acquire the backdoor. Seeing how well Ghost Girl made her moves, Kolter wished that Playmaker would be careful of her. While watching the Duel, Kolter was baffled how complex the Duel was, being unable to predict the outcome. After Playmaker won and obtained the program, Kolter went to analyze it. He believed he could crack the code, and noticed Yusaku was sleeping once more.
Kolter showed his analysis of Ghost Girl's program to Yusaku: the backdoor entrance to the SOL Technologies' mother computer, whose schematics looked like a maze. Kolter and Yusaku were nevertheless impressed by Ghost Girl, who managed to hack and find this. Kolter promised to be ready when the school was over, and Yusaku would be able to infiltrate the network the following night. On that night, Kolter showed the location of the data bank, warning that the path to it was filled with traps. However, he did make countermeasures against them, and Yusaku praised him for such speed. After Yusaku went into the LINK VRAINS, Kolter programmed an artificial device for Playmaker to hold onto to avoid traps, with a rope to prevent him from being detected, and gave directions to Playmaker where to go to. As security traps were set to stop Playmaker, Kolter programmed a "Sphere Kuriboh" as a decoy. After Playmaker passed Area A, Kolter saw there was a Data Storm. He wanted to give up, due to all the danger, but thought the Data Storm wouldn't be as harmful if Playmaker continued on.
After Playmaker defeated Prototype Ai-A, Kolter navigated him to the data bank. Kolter watched as Playmaker confronted Akira, and wished the former would obtain the data. As Akira claimed he would set things straight with the data, Kolter and Playmaker became furious, saying Akira understood nothing about them. Kolter watched the Duel, and was furious to be reminded that his brother was a part of the Hanoi Project. He was also shocked to hear SOL Technologies' data bank contained the name of the mastermind behind the project. Kolter was frustrated to see Playmaker could not attack, and Akira would win the next turn. Later, Playmaker defeated Akira and logged out, Kolter praised him for acquiring the data. The two hacked into Ai, and found out the Hanoi Project's leader was Dr. Kiyoshi Kogami, an employee from SOL Technologies, who alone worked on the project in secrecy. The two concluded SOL Technologies covered up the incident, else the company's reputation would've been ruined. Ai doubted the man could have done this on his own, and thought Akira was involved, but Kolter reminded him Akira, back then, was 16 and was not employed at SOL Technologies. Kolter and Yusaku failed to find the project's goal, but most shockingly, they discovered Dr. Kogami died seven years ago.
With the food truck positioned at the coast, Yusaku was doing research. Kolter invited him for a break, and gazed upon the ocean. Yusaku pointed out Kolter won't get many customers at that place, but Kolter assured him the famous coast was named Stardust Road, known for the luminous plankton that rarely gather at night, and thought the person living near the coast may have seen that. Kolter failed to gather new info from SOL Technologies' data, and Yusaku saw that data from ten years ago was actually deleted. Still, they knew the company was involved, even if Akira knew nothing about the incident before. Kolter felt a bit relieved that Dr. Kogami passed away, thinking their revenge was over. Yusaku reminded him they still didn't know about the goal of the incident, and Kolter still wanted to rescue his brother from darkness, even if they had no clue where to continue. Yusaku still remembered Varis knew some things. Kolter stated Varis was not seen recently, but Yusaku believed he was not the type that would simply disappear.
Inside the van, Kolter showed to Ai and Yusaku the footage of a camera, when a person turned into an Another, which happened six minutes before midnight. Ai noted there were no white hands taking the person into LINK VRAINS. Kolter told them the person had not recovered yet, and showed pictures of more Another patients in the hospitals. Ai and Yusaku knew this was the same accident with Blue Angel, who was infected by a virus. Kolter believed someone wanted people to be turned into mindless people, but has not find out what happened to their LINK VRAINS' avatars. Kolter showed more data, and Yusaku analyzed all of the Anothers were great Duelists with old-type Duel Disks, and all of them were hackers, too. The trio realized Playmaker, or Ai, were the targets. Yusaku reminded the importance of uncovering the truth behind Lost Incident, and as noted by Ai, they had to stop people from becoming Anothers. Kolter showed a list of possible targets, from which the first was Makoto Kimishima. Later, Kolter and Yusaku watched the Knights of Hanoi Dueling people, and turning them into Anothers. Yusaku decided to go into LINK VRAINS, even if Kolter believed he would be at a disadvantage, and Ai wished to feel secure. Surprisingly, they saw "Playmaker" battling the Knights of Hanoi, by stopping their programs and tossing them away from their D-Boards. Dr. Genome confronted "Playmaker", who revealed himself to be Gore. The latter stated he came to save Makoto, and knew Playmaker's identity, which displeased Yusaku and Kolter.

Kolter watched as Playmaker came to Gore. Later, Kolter and Yusaku went to find who was the Another virus' creator. At the van, Yusaku shushed Ai, who was amused to read all the criticism against Kitamura and SOL Technologies. Kolter analyzed that if the Knights of Hanoi took over LINK VRAINS, they'd soon find Playmaker. Yusaku believed they could prevent that by looking into the origins of Anothers virus. The next day, at the van, Kolter woke Yusaku up, reminding he had to go to school, and promised he'd continue working. After Yusaku returned, Kolter found nothing new. Ai believed Kolter gave up, who replied he was just getting started. Yusaku let Kolter rest, who went to cook some fries and cheese dogs. Yusaku and Kolter ate the food, and watched Blue Angel confronting Baira. Kolter and Yusaku analyzed the videos, and the latter saw Baira behind one of the Anothers victims.

Kolter drove his van to the warehouse district. He took a break when Yusaku went to rescue Naoki. One night, fearing he and Yusaku could soon be in danger, Kolter wrote a report, mentioning the Knights of Hanoi were real people. He named the report as "File No. 1007: Kusanagi Report". He noted the prowess of Playmaker and his allies, but feared the countdown to the day their destinies would change had already started. He also wrote that he still thought of his brother, Jin, and wished that the reader of this report would tell that to his brother when they meet him. He was visited by Yusaku and Ai, who felt something big was about to happen.
Kolter served a customer, who told him it would be the last time he would visit the stand, and Kolter suspected the customer would move away. The customer looked briefly at Yusaku, and walked away, with Kolter telling he was also located at the plaza. As the customer walked away, Ai claimed Kolter needed a mascot like him. Kolter replied Ai would make a lame customer, and was interested what was Yusaku doing. Yusaku pointed out the Knights of Hanoi have been purged from LINK VRAINS. Kolter noted Anothers' incident has been resolved, but also reminded Varis was still out there. Ai thought Varis had retreated, but Yusaku doubted that. Suddenly, Yusaku and Ai felt a pulse within LINK VRAINS, and asked Kolter to scan through the network. Kolter worked on scanning, and just as Yusaku and Ai sensed another pulse, Kolter saw the LINK VRAINS infrastructure changed. Kolter tracked Playmaker's activity, and as the pulse was emitted from the network, Kolter was shocked at the readings. Kolter monitored LINK VRAINS, and found a new reading of energy within the network. Yusaku and Ai joined Kolter, and watched hundreds of tentacles wrapped a beam that was shot in the sky and destroyed LINK VRAINS' cyberspace.
Yusaku, Kolter and Ai watched as the tower appeared in LINK VRAINS, causing the cyberspace to be absorbed. Since Yusaku obtained Ghost Girl's data, Kolter promised to look into it. Ai noticed the avatars were being absorbed, and not just buildings or roads - Yusaku knew this was Varis's doing. Kolter analyzed Ghost Girl's data, showing the Tower of Hanoi. Yusaku remembered Varis's words, and deduced if the Hanoi's game was over, the world would be destroyed. Kolter continued analyzing the data, seeing the link between the top, where the LINK VRAINS network was, with the underground erasing system, with the center being the core of the latter system. Ai was shocked, seeing how much data has been absorbed, as Kolter noted that speed has not decreased. Kolter counted six rings would be crafted from this system, one per each passing hour. He realized that once every ring is crafted, a pulse would be sent with high-density data, affecting every machine or program - every piece of technology existing in the world would cease function, as if the world has no computers at all. Ai thought it was safe as long as they did not enter the network, but Yusaku was certain Varis thought of that, and made something that would still erase Ai. Kolter continued his analysis, seeing even devices not connected to the network would also be affected, as an electromagnetic pulse would be sent out, even to erase Ai. While Ai was frustrated, Kolter was overwhelmed, knowing Varis made all of this just to erase an Ignis. The trio watched Kitamura - Akira's successor in SOL Technologies - battling a Knight of Hanoi, named Spectre. They saw how Spectre erased Kitamura, and the former threatened to do this to anyone that dared entering LINK VRAINS. Yusaku swore to stop the Knights of Hanoi, by shutting down the core. Kolter warned him there were no Data Storms in LINK VRAINS, except near that tower.
Kolter watched as Playmaker continued on to the Tower of Hanoi, and noticed Blue Angel Dueling Spectre, who defeated Kitamura earlier. He measured five hours and thirty minutes before the Tower of Hanoi was complete.
- Sam Black's announcement that he was voicing Kolter in the English dub referred to the character as "Koulter". Black later corrected the spelling.
