Ayumu "Osaka" Kasuga
More popularly known by her nickname Osaka (大阪, Ōsaka), Ayumu is a transfer student from Osaka. Tomo quickly chose for her the nickname "Osaka" contrary to Ayumu's behavior, which is different from what Tomo sees as the "typical" Osakan. Ayumu lacks the energy or motivation to dispute the nickname. She has a mind that works differently than other people, prone to daydreaming, absentmindedness, and non-sequiturs, but exceptional at answering very specific types of riddles.
