User blog comment:Just a passing through Master/Berserker of Conquistador/@comment-38196594-20190921140213/@comment-32751919-20190921142047

Because he don't stop fighting, it's driven him mad and even goes worse as the progress and that's lead to Aztec's downfall. But the plundering and massacre might also count as well. I think his driven mad case is similar to Magni, Thor's son.

Well it's still debated, some said he really want to end the human sacrifice, but some said he just want a treasure, nothing more or less.

Yes, thanks for the recommend, but....

Because Koishi would be triggered if his NP gen is too high lol
