Alright, so I'm looking for an anime I watched years and years ago and I've been trying to find it for days despite remembering jack shit about it and I'm wondering if some kind soul could help.
It was a shounen anime that started with the MC and his friends encountering a demon or a monster eating kids around his school, after being found out it proceeds to stab them all directly in the heart. They end up surviving and instead gain powers from it that manifests as lines across their body similar to the MC from SMT: Nocturne.
This is all I can remember, hopefully someone knows what I'm talking about.
Pic related, it's the MC from SMT.
Neo ranga?
