Akane Shinjō, a troubled teenager from the real world, sought escape from her problems. With the help of the alien Alexis Kerib, who exploited her negative emotions, she created the digital Tsutsujidai within the Computer World. This act plunged her real body into a coma while her digital avatar ruled the fabricated reality. Within Tsutsujidai, her avatar appears as a popular student distinguished by pale pink bobbed hair, reddish-pink eyes, cracked glasses, a dark purple jacket with pink trim, and a gray skirt—a stark contrast to her ordinary real-world appearance revealed after Tsutsujidai's events. Her personality blends outward charm with profound instability. She maintains a facade of kindness at school but secretly creates kaiju to murder individuals over perceived minor slights, like a classmate who ruined a sandwich she offered to Yuta Hibiki or a teacher who bumped into her without apologizing. Deep-seated isolation, depression, and violent mood swings fuel these destructive outbursts, often directed at her electronics. Her abilities in the digital world include sculpting highly detailed kaiju models for Alexis to animate, operating surveillance drones, and wielding powers tied to her repli-compoid avatar: a cat-like righting reflex, voluntary age alteration, force-field levitation, and "Instance Domination"—a cyber-linking ability later used to merge with Alexis during battles. Key relationships define her arc. She designed Tsutsujidai's inhabitants, including her former friend Rikka Takarada, to unconditionally adore her. Her fixation on Rikka and manipulative attempts to control Yuta—through seduction and later stabbing him with a boxcutter—highlight her inability to form genuine bonds. Alexis Kerib's manipulation fuels her destructive behavior, though she gradually recognizes his exploitation. Her development culminates when her kaiju Anti rescues her from integration into Alexis's kaiju form, Zegga. Gridman's "Fixer Beam" repairs her emotional wounds, while forgiveness from Yuta, Rikka, and Shō Utsumi allows her to confront her actions and return to the real world, symbolizing acceptance of reality over escapism. In the film *GRIDMAN UNIVERSE*, her growth continues as she uses Instance Domination to assist Gridman against new threats, demonstrating her redeemed role as an ally. Additional trivia notes her basis on Takeshi Todo from the live-action *Gridman* series, her color scheme's homage to *Transformers*' Shattered Glass Optimus Prime, and her later influence on the *Transformers Generations Selects* character Purple Wicked Convoy.
