Raiken arrived to the scene of the podey being having it's head knocked off.
"That... is just what I wanted to see at this time of day." Raiken said.
Then, he realised that the being still moved, and fired what seemed to be a Cero towards the shiigami that had currently enguaged it.
Raiken was behind it, and dashed fowards, his Zapakuto still sheathed, until the last moment, where he pulled it out from his obi sash, and delivered a swift cut to the being's arm, at the same time.
The aim was to sever the arm. If this thing was what it seemed to be, that would make killing it easier.
After all, not every being can survive having it's head blown off, and fire what seemed to be a Cero.
