I was the younger sister of Gekko Hayate, a ninja from the same class as Naruto, but ended up in a strange place during the Great Ninja War? ? ? He was also dragged into becoming a pirate by a rubber man wearing a straw hat.
Fortunately, the sword is there, and so is the chakra. It's just, what the hell is this place? I'm so angry.
(The female protagonist is Moonlight Hayate's sister, and the male protagonist is Zoro)
