Ruri Ninjabayashi

Engineered by the Mahogasawa Foundation, this advanced android serves as the dedicated shinobi for Souta’s adventuring group. Initially deployed as a powerful secret weapon to assist the Quest Dorm during the school’s intense athletic tournament, she brings unique combat capabilities to the team. Her personality is defined by a programmed little-sister dynamic with Souta, often manifesting in her habit of seeking verbal confirmation through frequent yes-or-no questions before executing tactical operations.
