Description
Do-ji pilots the XVT-MMC Geara Ghirarga, driven by admiration for his older brother Ogre to enter GBN battles seeking acknowledgment. He possesses master-level skill at annoying others.

Targeting beginners like Riku Mikami and Yukio Hidaka on their first day, he shadows them during a training mission. Witnessing them aid a mysterious girl, he feigns illness to lure Riku into activating Free Battle Mode. Ambushing Riku in his custom XVV-XC Zedas, Do-ji justifies his technically rule-compliant but exploitative actions. He defeats Yukio's GM III Beam Master but falls to Riku's GN-0000DVR Gundam 00 Diver after Riku resolves to fight.

The next day, Do-ji logs into GBN without a Gunpla while customizing a new unit. He observes Ogre's battles to learn, denying acquaintance with Riku and Yukio when they meet to hide his prior attack. After Ogre defeats Riku, Do-ji departs with his brother.

Seeing Riku's progress and his force's victory against the 7th Military Academy later distresses Do-ji, especially after Ogre remarks Riku won't remain a novice. This insecurity pushes him to obtain an illegal Break Decal from Tsukasa Shiba. During a timed mission with his force, Hyakki, he resists using the Break Decal installed on his Geara Ghirarga. Learning their opponents are the Build Divers, however, he confronts Riku alone. Losing to Riku's Gundam 00 Diver Ace, and seeing Ogre arrive to battle Riku, Do-ji succumbs to desperation and activates the Break Decal. His Gunpla goes berserk, ignoring his commands and attacking both Riku and Ogre.

Trapped within the out-of-control machine, Do-ji sobs in terror. After the Geara Ghirarga is destroyed and Ogre forfeits the mission, Do-ji tearfully confesses his sole desire was his brother's acknowledgment of his strength. Hyakki members reassure him that Ogre's acceptance is evident through Do-ji's inclusion in their skilled force.
