Kotomi Tsuda

Takatoshi's younger sister is a lively third-year junior high student with aspirations to follow in her brother's footsteps and head to Ōsai High. She's got a heart of gold—always looking out for others—but that doesn’t stop her from being super curious about the adult world. Her enthusiasm sometimes gets her into funny situations, like when she acts a bit like Shino Amakusa, their mutual friend. It's not uncommon for her to surprise Takatoshi by dropping off some adult manga when he’s under the weather. She's a mix of sweetness and adventurous spirit, always keeping things interesting!
