So the girl from the beginning was the chosen one, but Tenga interfered/ messed it up when he tried to save her?? And Kakura reached out to save Tenga, so they were both summoned instead for no reason without a way back???
If that's the case, he (unknowingly, but royally) screwed everyone over....
(I couldn't stand the incredibly annoying mc in the first story. I don't actually like Tenga & Kakura either, but Kakura's way better than the first mc.)
