Its been over 150 years since Shou left the soul society and went to the real world, after the death of his little brother. Over the recent couple of months he felt many strong spiritual energy. He got curious in what was going on, Shou went to go investigate. As he got closer to the city of karakura, he notice many of those strong energy were gone but some still lingered. He looked around the town to see if he can find any shinigamis. But if he did find somebody they wouldn't recognize him, it been so long since he showed his face to any shinigami or to anyone. In the time being Shou just walked around karakura town to see whats going on, hopeing to find a explanation.
