All of the Len'en 4 themes (not counting credits, ending and title). This game one of the best OSTs i've heard for now, specially Mitori and Chouki's. But most of the OST is also pretty awesome. Decided to post this here since no one has done it yet.
None of this is mine, Len'en is made by JynX, they're awesome making games and their OSTs (BPoHC Golden Chapter will be a thing so...!!!)
