Akane Shinjō is a troubled teenager from the real world who sought escape from her problems. With the help of the alien Alexis Kerib, she created the digital city of Tsutsujidai within the Computer World, plunging her real body into a coma while her digital avatar ruled the fabricated reality. Within Tsutsujidai, her avatar appears as a popular student with 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. She maintains a facade of kindness at school but secretly creates kaiju to eliminate individuals over perceived minor slights, driven by deep-seated isolation, depression, and violent mood swings. Her abilities in the digital world include sculpting highly detailed kaiju models for Alexis to animate, operating surveillance drones, and wielding powers such as a cat-like righting reflex, voluntary age alteration, force-field levitation, and Instance Domination, a cyber-linking ability. She designed Tsutsujidai’s inhabitants, including her former friend Rikka Takarada, to adore her. Her arc culminates when the kaiju Anti rescues her from being absorbed into Alexis’s kaiju form, Zegga, and Gridman’s Fixer Beam repairs her emotional wounds. 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, she continues to grow, using Instance Domination to assist Gridman against new threats as a redeemed ally.
