Edit: Updated the image because I forgot Bel's horn, which is an offense punishable by death.
Sometimes I manage to get a holiday related image out on time.
All the grow off girls are dressed up as their favorite One Piece characters! Mostly! Kind of!
Anyhow One Piece is the only manga that exists. Don't correct me on this, I won't listen to your lies.
In case you're a very strange person who's never read/watched One Piece you need to immediately correct this. Don't tell me it's too long it's completely worth it. Sometimes you need to put in the effort to experience joy.
Anyhow if you're too lazy to do the above then this is who they're dressed as and how they feel about it:
Adeen: Luffy. Not happy because they mostly forced her into dressing like him as a joke. Wanted to be Robin.
Joh: Chopper. Unhappy because forcing the shortest character to dress up as the shortest character is very offensive. Also wanted to be Robin.
Lawren: Robin. Dressed as Robin in order to keep the first two from fighting over who gets to dress as her. (Also secretly wanted to be Robin as well.)
Bel: Jinbe. Happy because she relates to large blue characters for some reason.
Alba: Zoro. Neutral because she's unfamiliar with the series but he was the closest the main crew had to a serious person.
Erika: Erika. Unhappy because she didn't understand the theme.
