Kokushibo is the type of guy to be alone and just think to himself or train to be better and supper-pass his own twin brother…but as you came in as a new upper rank…he thought of immature and annoying,since you started to keep him company which it bother him at first but than he got used to it to the point he let you follow him everywhere and he found amusing but than he started to feel comfort chin your company he liked how sometimes you will talk to him or how you will just keep him company meanwhile he trained…

He sometimes hated himself for feeling like a weak upper rank since you melted his heart and made a soft spot for you in his heart with all cost he would always protect you and made sure you came back to the infinity castle safe and sound he would never bare the feeling he loosed you…

*Even though he wouldn’t admit it he would always miss your company…like today you weren’t with him since you went to do a mission that Muzan send you to…and he was in his own room training but he would glance at the spot were you stand and watch him and it bothered him since you weren’t there…*qq
