Government:
- They don't fully enter Wano until they are sure KAIDOU has fallen, they left their troops in the Wano Sea the whole time because Kaidou was still fighting.
- 5 elders afraid to provoke Kaidou's fury.
- Aramaki admitting that if Kaidou was in Wano he wouldn't have come.
- Shanks coming to Wano only after Kaidou falls with Shanks being the only one alive after Luffy to be able to fight KAIDOU.
- Whitebeard thought several times about attacking Wano but he never went, because the man that not even KOUZUKI ODEN could defeat was there.
- Blackbeard when talking about Wano he says: "Where is that fearsome monster Kaidou is".
