this is an idea.
Another ProHero #dkbk in which there's a gacha game about hero and PH!Deku is addicted to it. The newest character that just released is the limited edition PH!Dynamight in his winter costume. Gameplay wise he's really strong, character design wise he's *ultra* hot. All the more reason for Deku to spend money for it.

And he does. He spends almost a quarter of his monthly payroll just for a single copy of it.
