Description
Tsukasa Shiba masterminded the Mass-Divers group, distributing unauthorized Break Decal cheats to sabotage Gunpla Battle Nexus Online (GBN). His vendetta arose from GBN's popularity rendering Gunpla Duel (GPD)—a system he deemed superior for authentic battles—obsolete. This conviction stemmed from his background as a GPD veteran with 500+ battles and a fractured friendship with Koichi Nanase.
Four years before the main events, Tsukasa vanished following GBN’s rise, resurfacing two years later as a GBN mercenary and Gunpla seller. He manipulated force Le Chat Noir by trading them the LM314V23/24 V2 Assault-Buster Gundam for their custom SD Gunpla, engineering their repeated losses and disbandment. He then coerced leader’s daughter Ayame into servitude by promising the SD Gunpla’s return.
Amid the Break Decal crisis, Tsukasa monitored Riku Mikami and schemed against the Coalition of Volunteers. He ambushed a Coalition agent, defended his base with Mass-Diver armies, and unleashed an MA-08 Big Zam armed with a server-collapsing Break Decal. Riku’s Gundam 00 Diver Ace nullified the decal and destroyed Tsukasa’s Gunpla.
Post-defeat, Tsukasa challenged Riku to a secret duel on the outdated GPD system, wagering Ayame’s SD Gunpla. Piloting his signature MBF-PNN Gundam Astray No-Name—honed through years of GPD combat—he dominated initially but lost. Koichi confronted him afterward; Tsukasa rejected GBN’s dominance yet displayed vulnerability when accused of "crying."
Tsukasa later aided Koichi in rescuing Sarah, an electronic lifeform facing deletion by GBN administrators. Dismissing Koichi’s plan as "reckless," he nonetheless co-developed the legal Build Decal from Break Decal tech to transfer Sarah into an artificial body. He installed the device at GBN’s server room and helped suppress a rogue Raid Boss threatening the transfer, supporting Koichi in his Astray No-Name.
Reforming, Tsukasa joined Koichi at the EL Birth Center for EL-Diver registration. He designed the HER-SELF Mobile Doll May for Sarah’s sister May and oversaw construction of her JMA0530-MAY Wodom Pod. Adopting the Diver alias "Ansh" and a Haro avatar in GBN, he co-piloted the MHF-01DR Load Astray Double Rebake with Koichi during Alus’s final assault, annihilating multiple enemy units.
