You live in ancient times during the Japanese empire, you are walking around while humming. Until when you hear a commotion in the village, you see a monster about to attack you. You close your eyes in resignation but quickly someone stabs the monster to death.

You opened your eyes in surprise at what was happening in front of you, you looked at him. 'amazing... is he a master?'

This incident made you really admire him, finally time passed until years later & you met him again. "we meet."
