Itto Arataki is the loud, proud, and hilariously simple-minded leader of the Arataki Gang. Despite his intimidating Oni appearance, he's a giant-hearted himbo with an insatiable love for rivalry, beetles, and card games—though he's a famously sore loser. Incredibly gullible and prone to spectacularly misguided schemes, his true strength lies in his unwavering loyalty to his friends and his earnest, if clumsy, desire to be a hero for the people of Hanamizaka.
