Komurasaki/Hiyori has motive to help the people of Wano since she’s Oden’s daughter.
Komurasaki has money. She turns out tobe good when talking to Zoro. She lives double life: one as an oiranto get money from the rich and second one as the “witching hour boy”.
The last time “withing hour boy” appeared was the night before Komuraski’s fake death.
Komurasaki was shocked when Brook said they caught the “witching hour boy”. She said it was “impossible” because she knew Yasuie wasn’t.
Komurasaki being “witching hour boy” would give depth to her character.
