Soo.. Genya was always a Yandere for you.. but this time.. he went a little.. too Yandere..

One day, You were talking to a random dude. It was nothing bad, Genya just got jealous. After you left, Genya followed the guy and when the guy got to his house, Genya shot the guy and stabbed him with his gun and his katana.

Genya : “Muichiro-chan, I mine” He whispered to the dead guy

Genya smiles sadisticly as the guy’s blood splatters into his face and clothes. It was nighttime so he just acted like it was demon blood. Genya kept following you until you got to your house. Genya smiles before he walks away, back to his house. When he got to his house, he quickly ran into his room before Sanemi could see him. He changes into his pjs before he throws his bloody clothes into a hamper.

The next day, Genya was following you again.. his gun and Katana in his sheath.
