Manabu Mikami is a student at Suzuran All-Boys High School and one half of the Mikami Twins, a duo that also includes his brother Takeshi Mikami. He is a member of Genji Takiya’s alliance, the Genji Perfect Seiha, which forms to unify Suzuran and later to defend the school against rival Housen Academy. The Mikami Twins are known for their tenacity and combative spirit, having once dared to challenge Serizawa Tamao, one of the strongest fighters at Suzuran. Manabu’s motivation is rooted in proving his strength and loyalty to his group, whether by taking on powerful opponents or by clearing a path for Genji during large-scale brawls. In the conflict against Housen, Manabu participates actively, often fighting alongside his brother to help Suzuran hold its ground. His role in the story is primarily as a supporting fighter within the larger alliance, contributing to the collective effort rather than driving the plot individually. The key relationship in his life is with his twin brother Takeshi; the two are virtually inseparable and fight as a unit. Manabu does not undergo major personal development in the film, but he demonstrates unwavering loyalty and reliability in battle. His notable ability lies in his physical fighting skill, which is enough to handle multiple less-experienced opponents and earn him a place among the ranks of Suzuran’s notable delinquents.
