Like Yusaku, he's is 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 [[Skye Zaizen]] is "Blue Angel". On several occasions, he has hacked surveillance camera's cameras in both LINK VRAINS and the real world alike with little effort. He is noted to routinely erase footage, article, and picture images of Playmaker in the network.<ref name="ep11" /><ref name="ep12">{{episode|Yu-Gi-Oh! VRAINS|12|ref}}</ref>

Kolter and [[Yusaku Fujiki|Yusaku]] discussed [[SOL Technologies]] and [[Knights of Hanoi|Hanoi's]] recent movements. Kolter told Yusaku about the [[Data Storm]] and suggested that it could help Yusaku enjoy Dueling again. He also mentioned revealed SOL was looking for [[Ai|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 decided to capture the AI A.I. and use it as a trump card against Hanoi , and he closed [[Café Nom]], despite Kolter protesting that he was expecting customers that night. The two hackers managed to capture Ai into the A.I. in Yusaku's [[Duel Disk]] during an attack from the Knights of Hanoi.<ref name="ep1" /> Kolter was surprised when a Data Storm occurred when "Playmaker" challenged the [[Number 10 (character)|the Knight]] to a knightDuel. He was watched the Speed Duel, worried when Yusaku Playmaker was sucked into a Data Storm tornado, and but he was relieved when Yusaku Playmaker won the Duel.<ref name="ep2">{{episode|Yu-Gi-Oh! VRAINS|2|ref}}</ref>

Kolter and Yusaku spent the next few days trying to figure out Aithe A.I.'s programming, but Kolter struggled to understand the complicated algorithms that Ai it was made out composed of. He then suggested to come coming up with a name for the A.I., to which and Yusaku decided to name it "Ai", a pun on "eye". He was also impressed that the [[Decode Talker (anime)|card data]] Yusaku obtained from the Data Storm was becoming a physical card. Trying to scan footage from "Ai's" memories caused the [[Varis|Knights of Hanoi's leader]] to track them down, however but Kolter was able to shut down Café Nom's power before they were found.<ref name="ep3">{{episode|Yu-Gi-Oh! VRAINS|3|ref}}</ref> The next day Kolter gave Yusaku the "Decode Talker" card that had finished materializing before he went to LINk LINK VRAINS to fight a [[George Gore|supposed Knight of Hanoi]] that had appeared.<ref name="ep4">{{episode|Yu-Gi-Oh! VRAINS|4|ref}}</ref> When the Knight turned out to be The Gore, SOL Technologies activated a program that prevents prevented 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 The Gore for their fight against Hanoi. Playmaker refused, not wanting to drag Gore into their fight.<ref name="ep5">{{episode|Yu-Gi-Oh! VRAINS|5|ref}}</ref>

Kolter discovered that the real identity of the famous idol "[[Celebrity Duelist]] Blue Angel" is was [[Skye Zaizen]], a classmate of Yusakuand the sister of SOL Technologies' security chief [[Akira Zaizen]]. He thought about suggested that Yusaku meeting meet with Skye 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 but 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.<ref name="ep6">{{episode|Yu-Gi-Oh! VRAINS|6|ref}}</ref>

After the Duel concluded and Skye was put in fell into a coma, Kolter hacked into the hospital's records to find out about Skye'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 Skye had been infected by a virus from Hanoi's [[Dark Angel (anime)|card ]], and that the only ones with the anti-virus were would be Hanoi themselves. [[Emma Bessho|"Blue Angel"]] appeared , claiming that she wanted a rematch against Playmaker. Kolter knew right away immediately that she was an impostor and instructed told Yusaku to ignore her because it was clearly a trap, but Yusaku went logged into LINK VRAINS anyways regardless because he felt it was his responsibility to save Skye.<ref name="ep7">{{episode|Yu-Gi-Oh! VRAINS|7|ref}}</ref> 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 [[Emma Bessho|Ghost Gal]]'s. He was displeased when Ghost Gal's camera stopped recording, making preventing him unable to watch anything inside LINK VRAINSfrom seeing how Yusaku was doing.<ref name="ep10">{{episode|Yu-Gi-Oh! VRAINS|10|ref}}</ref> 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 Gal to enter the Data Storm; she had her cameras record the Duel between Playmaker and Varis, allowing Kolter to watch it. Kolter learned of the Ignis, A.I. with free will that Varis claimed wanted to overthrow the network, but didn't believe that Ai would do such a thing.<ref name="ep11">{{episode|Yu-Gi-Oh! VRAINS|11|ref}}</ref>

Kolter was glad that relived when Playmaker won against was able to defeat Varis , and he carried him out of his pod after he logged out since the former took a lot of strain during his Duel. Since Yusaku was interested what became of expressed interest in Skye's condition, so Kolter went to show showed him that she was recoveringhad recovered. Yusaku fell asleep , and Ai commented on how lazy he was, but Kolter claimed heroes needed to rest. Ai started bragging, so Kolter went began to analyze what kind of the program that he ate had stolen from Varis. Realizing Kolter would look into his "private parts", prompting Ai called him a pervert and refused to say anythingclam up. Once Yusaku woke up, murmuring about the Ignis, and Kolter sensed noted that he was thinking what Varis had told them about Ai. Since they did not know how to prove if Ai was actually alive, Ai claimed it, was indeedalive, was alive. Ai and he used the program that he had obtained from Varis to recover his body back. However, Ai's size didn't impress Yusaku and Kolter, who instead tried to analyze if Ai had regained some of his memories, even if Ai wanted them to be excited that he regained his body.<ref name="ep12">{{episode|Yu-Gi-Oh! VRAINS|12|ref}}</ref>

Inside the van, Kolter showed to [[Ai]] and [[Yusaku Fujiki|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 [[Skye Zaizen|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 [[George Gore|"Playmaker"]] battling the Knights of Hanoi, by stopping their programs and tossing them away from their [[D-Duel Board]]s. [[Dr. Genome]] confronted "Playmaker", who revealed himself to be the Gore. The latter stated he came to save Makoto, and knew Playmaker's identity, which displeased Yusaku and Kolter.<ref name="ep22">{{episode|Yu-Gi-Oh! VRAINS|22|ref}}</ref>
