Erika Itsumi was a second year student at Kuromorimine before she was expelled. Erika herself has an older sister. Erika is a medium-sized girl at 5'2 with long silver hair and a pair of light blue eyes. She has a slim figure and quite the angry, cold and arrogant personality. She will not cooperate and she will get violent. Erika was commander of a Tiger II heavy tank, which she now misses. She is very sad about being expelled from Kuromorimine. She is 17 years old and was born in Kumamoto City
