* THIS IS A SERIOUS SUGGESTION *
Pain - Chikushodo swimsuit version absolutely needs to be in the game. Her basic character is a bad character in anything other than ranked battle and even then she requires other pains. Additionally, her boost is the only thing she really adds as her mystery ruins her as a character for being easily countered and nonprompt without much damage behind it. Even worse, it has a massive cooldown of 3 rounds making it a one-time a battle thing, and her rhino and 10 combo do very little damage as well. All of this makes chikushodo unuseable in a "main" team.

So as you can see her character could really use a buff. However, instead of buffing her directly, make a new swimsuit character of her to make profit on, as well as appease anyone who really likes chikushodo. Nagato's recent appearence coupled with swimsuit chikushodo would definitely increase spending on pains for ranked battle. More money and a relatively weak character gets a buff, why isnt this a thing?
