Nanaya Mutsuki is an unlucky man. When he was sixteen years old, he had nowhere to go and was heartbroken. He received an olive branch from an organization called Chaldea. With an attitude of doing anything, Mutsuki became one of the 48 masters.
As a result, Nanaya Mutsuki met the friend who changed his life here - Fujimaru Ritsuka.
However, when he opened his eyes again after sacrificing his life for his friends, he found himself lying in the woods and arrived in Japan in the Taisho era.
Tonight, the bright moon is still high.
