Ikasuze! Peace

The monk Kouta was planning to die. Born into a temple, Kouta was handsome and from a wealthy family. He'd lived an easy life without any complaints. But the other day, he was told he only had a short time left to live, and he decided to give up on the world and die. But then the angel Pin-chan suddenly appeared and declared, "I've come to save Kouta!" Kouta decides how to die, and the angel decides how Kouta should live. As the two return home, their battle unfolds, only to discover buried gold coins from a robbery in the garden...!?
