From Chibi Manga:
The everyday misfortunes that occur are from her prayers to God. She believed that her parents and the sister that she loved so much died because of her unhappy predisposition. She canâ€™t even make friends, but all she does is just continue to pray everydayâ€¦
And then one day, she met Koini who is invincible at fighting and Kinzou who is invincible against love and was told â€œwe will protect youâ€!?
This is a high tension love comedy.
