A plot could revolve around Eri and Kouta having to face a common enemy from their pasts.

They would have to overcome their own traumas related to this enemy and find the strength within themselves and in each other to defeat the foe.
One plot idea could be Eri and Kouta teaming up to help other children in need.

Another idea is a story where Eri and Kouta discover a hidden part of their quirks. They could go on a journey together to understand these new aspects. Maybe they stumble upon an old, forgotten place that somehow unlocks this new potential. They would then have to learn to control it while also dealing with the excitement and fear that comes with such a discovery.
