Akane Kobayashi

A girl who likes to sleep in class but outside of school she holds a part-time job as she loves to make money. She has also shown great concern about her appearance and weight, causing her to put herself on crash diets. She's very ditzy sometimes, like when she walked into the classroom and Anthony (an American exchange student) said "Hello!" in English: she came to the instant conclusion she had woken up in America.
