Tanais

cheerful fishgirl braving the seas with her best friend (pending)

mute but very energetic and the two have a custom sign language

optimistic to the point of looking dumb (she's not stellar but she's not an idiot)

is of average strength... by fishpeople standards

got kicked out of her community after taking a bite out of a devil fruit that was supposed to be for sale

her fruit power allows for creating food out of thin air (granted one type of food but still) so they don't know what they lost

can't swim as the result of eating a devil fruit but also can't drown as per being a fishperson

tired of fishing her out of the ocean, Shinjay made a high buoyancy ball that she wears on her waist - it helps her stay afloat so she's easier to find
