飛鳥 伊麻

The younger sister of Mirai. She is like a weaker version of Setsuna, and was sent to send Kosame back, but after discovering both Ren and Mare, she decides to deal with both of them too. Mostly appears in Mare's Route in Eternal Heart.
Her memories have been wiped out and thus, she can't remember anything about her family or older brother. Ima uses a bow-and-arrow to attack. She is mentioned in the first game when her brother tells that she was suddenly kidnapped.
