Summary
Tetsuo Ishimaru serves as the Devil Bats' secondary running back, wearing jersey number 30. Standing at 168 cm and weighing 59 kg, he is a second-year student who previously attended Jimichuu Middle School. Sena recruited him onto the team after taking over half of his paper route, leveraging Ishimaru’s background as the track and field captain, which earned him the nickname "Track Star" from Hiruma. His speed is notable, with a recorded 40-yard dash time of 4.9 seconds. Ishimaru’s defining trait is his extreme lack of presence, which allows him to operate as a stealthy asset. During the Koigahama match, he suffered an injury because Sena could not distinguish between his cleats, yet he remained on the team where his obscurity became a tactical advantage. Opponents often curse him after plays, lamenting that they did not notice him or that he had no presence. He is frequently referred to by titles such as the "Stealth Running Back," "Shadowless God Of Death," or simply "plain" Ishimaru. In gameplay, he acts primarily as a fullback, blocking for Sena on screen passes and trick plays. Like Yukimitsu, he lets his hair grow out, though no one seems to notice this change either. Ishimaru is depicted as a massive pushover who accepts whatever happens around him without resistance. His personality is defined by his passive nature and his signature catchphrase, "It's alright."
