Yep. He killed them. In the previous chapters, he also killed some elders of the Rain clan. But, if he were to kill too many, woudn't that disturb the real world? It will, but, he doesn't really care - they are his enemies. Anyway, I'm looking forward to see what's happening in the real world.. And how long it'll take for the Rain clan to realize that he's that kid who was supposed to be dead.
