Kira's world was full of dark clouds.
The only light was being brought each morning by Captain's smile, but Kira was afraid of those very mornings, too.
You are not fit for the Third Squad, for Gotei 13, for Shinigami - every day he was scared to hear those words.
Today Captain called for him unexpectedly, and now Kira - a small bundle of a great fear - was standing before the door of his office.
You are not fit.
Well, he won't hear anything worse than that anyway - he mustered up his courage and entered.
Captain was accompanied by Rangiku-san. Both of them were smiling, especially Captain who said:

"We decided wit' Rangiku to adopt ya."

Anything worse?
Before his world went all black, Kira regretted his lack of imagination yet one more time in his life.
