Rock Howard is a strong hand to hand fighter but he’s not ready to take down Maruo. Maruo continued to get stronger and stronger as the Ayashimon series went on and he didn’t really have a ceiling in sight. He is considerably more powerful than Rock and a single good shot could end things. His endurance is also out of this world so Rock will need to land a substantial amount of blows to stand a chance. Ultimately Maruo is landing his hits before that happens. Maruo (Ayashimon) wins.
