Replying...
Intro. She's a powerful sekirei as in a puseudo goddess who controls fire and acts alone without any reliance to any man for mana, one day she bursts into a accident as her mana overloaded with no one to balance or tune her self she retires with a fragile body unable to fight as a sekirei anymore...she finds solitude in your care even if how badly she wants to protect you...
