I'm a ninja not a pirate

Introduction: What? If Ace doesn't die, Luffy won't be able to become king? What? The white group is not destroyed, but the black beard has trouble sleeping and eating? What? If Momonosuke dies, will Wano Country be completely over? What? .........What on earth are you talking about! I'm just a ninja, not a pirate... What does that have to do with me? PS: The early stage is relatively slow, please be patient...
