Sophie

Sophie is a recruitable character that can be found on Aquarium City laying on the ground after falling down, and seeing no reason to get up because of her crippling depression.

You must pick her up to recruit her, and as you move on the map, she will constantly keep falling again and again, and as you constantly pick her up, her mood gets better, until she gets completely recovered.

Since she is too depressed to be a party member, she starts out by being an item in your inventory. At this point, she doesn't have a fullscreen artwork either.

Pick her back enough, and she will be a party member, but still depressed, weak and pathetic, having the worst stats in the whole game. Continue picking her up and her stats and class will slowly increase from "Destroyed" to "Recovering", then "Feeling better" and finally her original title: "Sweet girl". Then her portrait changes and she gets her fullscreen art.

Her quirk in battle after her sidequest ends is being a magic version of Bite, being capable of dealing massive amounts of damage, while also being the only character in the game with the skills "earthquake" and 'hail'.

The game itself describes her as:

"She is trying her best. But everything keeps bringing her down."
