After killing all person in village kita was standing infront of the girls dead body. He never able to control his anger in his past life. When he was kid he live alone in house. He live a lonely life until he meet a group of three friends in his new school.
(In past world)
Kita never have a intrest in enjoyment, he live with his grandparents. His parents was come to meet in vacation. He never cry for his parents. When he come in high school a group of three friends they come ask his name but he didn't answer them, he became an introvert because he didn't talk to anyone and live all day in his room.
His seat left side one boy of that group. His name was shukota he always a smile boy, he come to kita and ask his name, but kita not answer him. In class time when teacher was teaching them all class was laughing by shukota joke. Teacher ignore him by short panishment because she knows that he is smart boy who always come in first place in class. In lunch time kita was sitting alone by seeing that they come and share his food with him. After lunch the other two of them introduce them to kita first one name is shika and second one name is Hakatshuki they become friends, they are the first friend of kita. But kita always reply them by saying hmm. Kita spend time with them slowly slowly he start smiling in 3 year they become a true friends. They always ate together, play together and Rank in top position together. In 3 year shukota make a girl friend, he show her photo to kita because he was his bestfriend. Kita was shocked by seeing her because he also like her. he never say anyone about that and always help him to make them a happy.
One day shukota was sad, because she breakup with him. Kita always motivate shukota and always try fix there relationship but she left him. After she left shukota became serious and his smiley face lost and get a serious face of kita. And kita serious face was lost and get a smiley face of his friend. After that kita leave the city because his parents take him with them.
(Kita) When I was younger I have same anger like that. But by them i able to control my anger and now I lose my control on it. I make a grave for that girls and leave that village.
(Next day)
I was in middle in way of nearest city. I hear a sound of crying, and follow it. When I get closer I show the group of bandits was going sale the slaves. I make traps because that time don't want to lose my control. When they come trap activate and stopped his carege they put his sword on his hand and ready to fight. I set many traps so I came and activate traps they get captured in traps that time they was sleeping because I use sleeping herbs on traps. I came closer to carege and released the slave there was one elf girl and two human girls are there. I take them with me and also take responsibility of them because I not want anything happen to them before happened ot other girls who i rescue.
If I take them with me then there any possibility of that I can able to control my anger they were happy but elf girl showing attitude infront of other girls and say thank to me. I kill bandits and take there something to get prize on there heads.
