"YOU KILLED ITSUKI AND REN!"
Weren't the same asshole that was ridiculing Naofumi for his incapability to do damage? How the flying fuck did he overpower them then? Does Motoyasu even think, like, at all?
@SSS26032002 actually, what happens is that if a hero dies, that weapon cannot reach the next successor unless everyone else dies so they can restart the ritual to get the new heroes.
If one of them dies, the others are able to continue living, but it is prophecized that their world can only be saved by the FOUR heroes. In effect, to cover their bases, all heroes must survive to the end so there is no risk in them misinterpreting the prophecy.
Essentially, what Fitoria would have done is kill the current heroes, take their weapons, then do the ritual herself so the next chosen heroes can be transported to her world.
