Akari Yamamoto

Akari is Rio's blunt step-sister. She has had a few relationships and doesn't really like the "good-guy type." She was in love with an older boy who lived in her neighborhood and kept a bracelet he threw away after not giving it to his girlfriend. After she moves to an apartment near Yuna's, she becomes friends with Yuna and falls in love with Yuna's childhood friend Kazu.
