Akiko Kobayashi is Tsukiko's twin sister. Like her sister, Akiko is self-assured and confident in herself, but unlike her sister, she's quite friendly and outgoing. She's intelligent, but impulsive, and sometimes can't help herself but to stoop to lower levels if it means she's correct. She's not great at comforting people, and she swears a lot more than her sister. She is from Japan.

Voice Description: Raspy and aggressive in a way, always too loud for no reason though she doesn't mean to be, her voice both does and doesn't fit her positive personality yet she doesn't care, she also somehow has a southern accent.
