SULLEN PSYCHO (AKA: Project Psycho) features a dark fantasy setting the protagonist has no idea how he's ended up in, but instead of going out, he keeps diving in. What the hell, Allan? He's charming, care-free, and goes with the flow, long as he can! You control him throughout his weird adventures. He never (or rarely) questions the absurdity of his situation. Why should anyone else?
Sullen PSYCHO is not necessarily about a psycho, but a random fellow, Allan, who is where he's not supposed to be. But now that he IS here, he must navigate through the dark, mysterious, captivating castle he's found himself in. Therein he'll meet many entities, be it people or weirder creatures, friend or foe, alive or DEAD!
He'll meet Succubi and Talking Skeletons, Iron-clad Knights and Old Frauds and Tricksters who not unlike him, are hoping for a good time:
A Good Adventure.
