Hello Nid! I wonder - do you have a piece that is after the battle, but they are still thinking of the battlefield?
Something like: this song + Relaxed Game Title BGM + some bursts of fast drums, because they are still reminded of the fight.
All the game music is either very sad or very frenzied. Which makes sense for most RPG! I hope for something in-between. Like: they are eating hanami dango; they're crying because the dango reminds them of someone. But they are still happy the fighting is finished. They are happy to start over.
