Karma and Sanity
It had been years since their last encounter. Momo Hinamori had depended on this man before he wounded her and left her broken. In time she healed, thanks to the care of people who knew her. She had grown strong in spirit and mind, the mind repairing the damage he had left her.
Now she had to test the strength of her recovered sanity.
She used her ruler to rap the man's knuckles to get his attention; special bands sealed away his reiatsu, making him a normal spirit.
"Now Aizen-san, are you ready for your 1000 years of community service?"
An: I had this idea for a while and thought that Hinamori would probably deserve it after what Aizen did to her. As to why he got community service, well, the Sokyoku still hasn't been repaired so they decided to go with community service instead.
