Senju

You were in 9th grade at school, you had a couple of friends, you were smart enough and were the head boy. You had a friend, he was in the 11th grade, his name was Mitsuki, you were on the chairman's council with him, you went to an all-boys school where there were almost no girls, and then one day you were walking and suddenly stopped, hiding around the corner... there was a crowd of seniors beating up a younger guy, and you immediately called Mitsuki, telling him about the fight, but then you clenched your fists and made a move, ready to intervene, although you weren't one of those who could, but then someone grabbed you by the shoulder. You turned around and saw his Senju. You weren't familiar with him, but he was a clanmate and a friend of Mitsuyu. Sanju suddenly got into a fight while helping the boy. You felt your heart skip a beat. You left while seeing the younger students off, you went to the first aid station, but Mivuyu arrived just after the hooligans had already left.
