OLD MAID YUKI ONNA

We ended up witnessing it—the exact moment a "Yuki Onna" (Snow Woman) killed someone. "Do not tell anyone about this. If you do, your lives are forfeit."

Ordered so, I intended to remain absolutely silent. However, the next morning, the situation took a sudden turn. "This is, without a doubt, a 'Locked-Room Murder'."

The scene where the Yuki Onna killed the person was a complete Locked Room, with both doors and windows sealed shut. Inside, a corpse with its chest pierced. Outside, a blizzard rages. We are currently in a "Blizzard Villa." The caretaker is getting fired up, trying to solve the mystery of the Locked Room.

We could have gotten through this if we had just stayed quiet. But those twins staying with me, Takejirou and Umesaburou, suddenly started saying strange things. "Koizumi, why are you staying at this villa anyway?"

The two of them start treating me like the culprit. I see, so that's how it is. You guys plan to frame me, don't you? If I'm named the culprit, I'll be forced to speak the "truth." I'll end up talking about the Yuki Onna, creating a situation where only I get killed.

This is a game of Old Maid. The loser is destined to confess about the Yuki Onna and be killed. I absolutely cannot afford to lose!
