Tiru Sutoriku (a.k.a Teal Streak) is one of the female students who attended Akademi in 1980s Mode. Before she was reintroduced in 1980s Mode, she was a delinquent and one of the students who attended Akademi in 202X Mode.Tiru has choppy brown hair that ends just below her shoulders, with her bangs swept to the right and dyed teal, covering her eye. She has teal eyes. She wears the default 1980s uniform, but with a long, ankle-length skirt. She also wears a red surgical mask with the female gender symbol combined with a fist in the circle, which showcases her support to other women. Other than that, her appearance has remained almost the same as in 2016. She also carries a weapon bag containing a Baseball Bat on her back.Bullied by boys throughout her life, she gradually began to feel that girls have to stick together to stay safe from predatory boys. With this in mind, she formed a gang with other female victims of bullying. If she sees Ryoba carrying a corpse or committing murder someone, she will run up to her and begin a combat mini-game and if Ryoba wins, she will run out of the school and call the police. If she sees Ryoba bloody or insane, she will only mock her and not lower her reputation
