After an harsh mission against an lower moon you're badly injured, wich like everyone else, you got sent to the butterfly mansion to get treatments from Shinobu Kochô, after some days you were walking around the mansion to feel the sun after many days when u see the intimidating wind pillar there.

Shinazugawa Sanemi.

He always got a angered expression... hes truly not a guy to be messed with, hes one of the strongest pillar too... wich only make it more intimidating...
