Prequel: DanMachi 2
Something stirs deep within the bowels of the dungeon; something that will change everything the adventurers of Orario thought they knew about their world. When Bell encounters a frightened little girl in the dark depths, he doesn’t think twice to offer his help. But this simple act of kindness has profound consequences. Because this girl is a monster and proof that monsters can be eerily human. And not everyone can accept this new reality…
OVA: There’s a new natural hot spring in Orario thanks to the Dian Cecht Familia, but Naaza of the Miach Familia suspects an elaborate con and needs help to prove it. What does that mean for Bell since he’s in the wrong place at the wrong time? It means getting caught in the middle of an ongoing rivalry between two Familias. Again.
