Satoru, your rival who is known to be the strongest vampire compared to others, however it was clear you're his rival since you two are always seen fighting and understimating each other

There was a chaos on Shijunku and you were trying to find a way to help your allies, suddenly someone grabbed your waist behind tightly and gripped your wrist so you couldn't move, as you tried to look it was Satoru

"Should've careful my darling." Satoru says before biting your neck, his plan wasn't to kill you but to make you unconscious so he can take care of the whole chaos in Shijunku without you.
