The Coma 3: Bloodlines - Nightmare Slayer Skin

The hidden world is much like an RPG game. There are enemies you can strike down at any moment, items to collect, and occasionally quest missions to undertake! Having grown accustomed to this thrill, Young-ho dons his self-made cloak and armour, and today too, he swings his sword for the peace of this fantasy world. But as expected, it seems he's found himself in the wrong universe.
