'''Asaka Mutsuba''' ({{Ruby|六|むつ}}{{Ruby|葉|ば}} アサカ ''Mutsuba Asaka'') is a character in the ''[[Yu-Gi-Oh! GO RUSH!!]]'' anime. She serves as the president of the [[Mutsuba Heavy Machinery]] and the de-facto leader of [[Mutsuba Town]]. Asaka, along with "[[Yuga Ohdo|That Guy]]" and [[Yuna Goha]], was responsible for the creation and distribution of [[Yu-Gi-Oh! Rush Duel|Rush Duel]]s.

[[Tell Kawai]] visited Asaka, apologizing for his intrusion, and Asaka asked him what his business was.<ref name="ep12">{{episode|Yu-Gi-Oh! GO RUSH!!|12|ref}}</ref> A [[Yu-Gi-Oh! Rush Duel|Rush Duel]] between [[Yudias Velgear]] and [[Zuwijo zir Velgear]] had begun atop [[Mutsuba Tower]], and Zuwijo had used the power of the [[Earthdamar]] - a substance Tell Kawai had previously extracted from [[Yuhi Ohdo]] - to materialize and clad himself in his "[[Voidvelgr Requiem (anime)|Voidvelgr Requiem]]". The power was also being spread across [[Mutsuba Town]] by Mutsuba Tower's radio transmitter, resulting in monsters like TellKawai's "[[Kappa Avenger (anime Rush Duel)|Kappa Avenger]]" being partially materialized. After Asaka ordered Tell Kawai to be concise, he explained that the soul of the Earthdamar's origin, Yuhi, had been drawn into "Voidvelgr Requiem", though Tell Kawai wasn't sure what would happen to Yuhi. Though initially unsure what Tell Kawai wanted her to do about the situation, Asaka took [[EX6]] to Mutsuba Tower, where she faced off against Zuwijo's servant, [[Mitsuko Hiramori]]. Asaka easily withstood Mitsuko's attacks using EX6 and carved a portion of the tower away to extract the Earthdamar, successfully stopping it from materializing more monsters, though "Requiem" remained materialized with Yuhi's soul trapped inside. Asaka asked Tell Kawai what would happen to Yuhi if Zuwijo won the Duel, and Tell Kawai admitted that Yuhi's soul could remain trapped inside "Requiem" if it wasn't destroyed during the Duel. Fortunately Yudias was able to do so and defeated Zuwijo, and Asaka moved away from Mutsuba Tower once she noticed the phenomenon had stopped.<ref name="ep13">{{episode|Yu-Gi-Oh!

Though the Earthdamar was of interest to [[Tell Kawai|TellKawai]], Asaka viewed it as an uninteresting and disgusting liquid and relinquished it to [[MIK (organization)|MIK]].<ref name="ep25">{{episode|Yu-Gi-Oh! GO RUSH!!|25|ref}}</ref> She reappears again shortly after Asaka was holding a tour for children from [[Mutsuba Kindergarten]] at the [[Mutsuba Recycling Plant]], only to be interrupted by [[Yuhi Ohdo|Yuhi]], his twin sister [[Yuamu Ohdo|Yuamu]], [[Manya Atachi]], [[Bochi]], [[London KirishimaManabu Sogetsu]] and [[Netsuzo ShinjitsuNyandestar]], Yuhi begging Asaka to shut down the recycling machine as they believed [[Yudias Velgear|Yudias]] steal had been drawn into it following his transformation into a shirt. Asaka was incensed by the arrival, though proved to be too late to stop Yudias supposedly being recycled into a pair of gloves and relinquished them to the [[UTS]] spaceshipcrew.<ref name="ep24">{{episode|Yu-Gi-Oh! GO RUSH!!|24|ref}}</ref> Kawai later visited Asaka, using informing her that Yudias had actually fallen into [[Zuwijo zir Velgear|Zuwijo]] and [[Mitsuko Hiramori|Mitsuko's]] hands and that they had visited him to extract Earthdamar sap from his humid lab to restore Yudias. Kawai grumbled over the waste of the Earthdamar, but Asaka reminded him she didn't care about the substance and ordered Kawai to reveal why he had visited. Kawai revealed that "his" instruments had picked up an apparent asteroid approaching from outside their solar system.<ref name="ep25" /> Asaka and Kawai boarded [[Heavy Cavalry|EX6]] to catch after [[Yuamu OhdoSpace Treasure|a spaceship]] who fell took off from [[Mutsuba Town]], Kawai noting it had long been rumored to be buried beneath the spaceship town. The truth proved considerably more dramatic, as it was midthe entirety of Mutsuba Town had been constructed above [[Val-flightValvelgear|a Velgearian spaceship]] buried beneath the ground, and the larger ship also took off. Pursuing the Space Treasure, Asaka and Kawai assisted Yuhi in rescuing Yuamu from the ship, catching the twins in the bucket of EX6.<ref name="ep26">{{episode|Yu-Gi-Oh! GO RUSH!!|26|ref}}</ref>

In the second season, Asaka is banished to the [[Alien Residential Area]] by [[MIK (organization)|MIK]] due to her affiliation with aliens, where she remains for two years. After MIK takes out [[Yuna Goha]], she sets up a resistance group and raids MIK headquarters as an attempt to buy time for Yuamu and Yudias to infiltrate the [[Goha CorporationCompany]] building. While Asaka and her team were successful in stalling for long enough for Yudias to pick up a [[Maximum Monster]], she ends up being taken out by [[Energy Copyko]].<ref name="ep57">{{episode|Yu-Gi-Oh!
