So I just got kaya from ussopp's story.

I just got Kaya no. 501 but I'm not seeing her in the character list for the Japanese version. I wanted to see if someone else got her and do they know if she is any good. My friend code is 939 506 303 and that's for the japenese version If you need proof.

She's not that bad.. She can act as a good replacement to Vivi if you dont have her already, the have the same captain skill of healing every turn, but unlike vivi's healing, kayas lasts for only 4 turns.

I know she's possible for the reroll but is there proof of this ? i may rerun the story to see if i can grab her too.

She's a gacha unit.. I doubt you can get her from the story island.
