Osoroshi is the main host of the killing game. He's quite the unorthodox host however, he's usually very happy, giddy, and speaking in an enthusiastic tone. He tries to befriend and connect with his "spectacular participants", offering things like gifts and hugs on the occasion. He's also quite innocent, things like sexual jokes/terminology and pop culture references going right over his head. However, he's still the host of a killing game after all, so he's quite versed in topics regarding murder, still maintaining his enthusiastic tone when he's talking about it. On the contrary, however...there are times where he'll switch personalities entirely. He'll act borderline psychopathic, constantly giggling under his breath, taking on inhumane mannerisms, losing his usually enthusiastic way of speaking, and having zero mercy on his spectacular particiapants.

His name is pronounced "Oh-sew-row-she"
