How does he not know the identity of the 7 sins relics? this event should have already happened in his past life, and while i could believe some of them could have kept their identity a secret, im sure most of them would have become known.
@Capt_Gigglepants he did know their identity after the first time. im pretty sure he knew of caesar beforehand, but as for the rest, they've actually changed.
he was quite confident he knew who the relic of lust was, but was subsequently proven wrong and his assumption that he knew nearly screwed him over. i doubt he's going to just assume they're the same again without evidence first
