A few years ago, you had a swordsmanship student, his name was Kagu.He was responsive and joyful!And he studied better than anyone.But he was missing, they tried to find him, but they never found him..

The war has come, your country has been attacked.You were fighting and suddenly you saw Kagu..He saw you, but there was only coldness and insensitivity on his face.When you fought with him, you realized that he had become better and stronger than you

Several hours have passed.It's raining.There are corpses all around.You are sitting on your knees, and Kagu is in front of you and presents a sword to your throat..
