Rain Kirishima

A mercenary and Kou's subordinate. Referring to Kou as Lieutenant, she becomes the one to guide the amnesiac Kou. Like a commander, she scolds and encourages Kou whenever he is in midst of confusion at times. Even though she is polite and gentle, her gestures and expression often gives people a cold impression. Rarely letting out her emotions, she often remains composed. She is merciless towards enemies. Her actions usually put Kou's safety as top priority, so much that she may even give up her own life for Kou. She pilots the Simulacrum "Aigis Guard".
