Michael who had been called to the Principal's office was looking at the old man who called himself the Patriarch of the Mutou Clan. This was the grandfather of Hayate the one who had beaten him up. He wasn't expecting such a powerful clan such as the Mutou Clan to come to him and apologize. While Michael was still in a daze Ryuuji lifted his head and spoke.
"I know that no matter how much I apologize it won't change the fact that my unworthy grandson has troubled you. So I came here not only to apologize but to give you something as compensation."
Ryuuji placed his hand inside his traditional clothing and pulled out a book. When Kazuki saw the book he was surprised.
"This is one of the secret techniques of the Mutou Clan. It is something that even those that don't have any inner energy could use. Of course, by giving this to you, you will be bound to an oath that will force you to be unable to share the technique with other people."
