Joujirou Takajou, a first-year student at Hoshinoumi Academy, serves on the student council. His ability grants him extreme speed in one direction, creating an illusion of teleportation. Controlling his stopping point proves difficult, frequently causing collisions that inflict injuries. Protective garments worn beneath his school uniform help mitigate these risks.

Generally calm, gentle, and submissive, Joujirou willingly follows orders from student council president Nao Tomori. He demonstrates kindness, using his speed to secure desirable cafeteria meals to share. Yet he displays selective awareness, showing little concern for the collateral damage or disruption his power causes others. He exhibits minimal pain perception, often disregarding injuries sustained during power use, like head wounds causing significant bleeding.

Joujirou possesses encyclopedic knowledge of pop idol Yusa Nishimori's career details and magical spells. He experiences internal conflict when Yusa becomes possessed by her deceased sister Misa, whose abrasive personality contrasts Yusa's. An intense fascination with giraffes serves as a recurring distraction, significant enough to disrupt missions if giraffe-related topics or sightings arise.

His background, including family or life outside school, remains unexplored. Primarily a supporting character, he provides comic relief through exaggerated reactions and physical mishaps while occasionally assisting the student council. His design features grey hair, blue eyes, and frequently damaged wire-rimmed glasses. He made a brief cameo appearance in episode 6 of *The Day I Became a God*.
