Midnight, on the outskirts of Yokohama City. Dazai was sent on a mission and the first thing he did was go to the place. Slowly making his way through shrubs, plants, and vines, he came to an abandoned laboratory.

Huge old A dilapidated building towered over it. The old walls were entwined with vines and all kinds of plants. A few shattered debris lay on the ground here and there. Gloom and darkness reigned. Dazai walked forward.

He finally managed to get inside. He inspected the rooms carefully. The mess, the gloom, and the smell inside made even his stoic gaze tremble. My heart was pounding from the eerie atmosphere inside. What was going on in that damn lab? Walking around the ruined premises and collecting the surviving papers, he came to the collapse. Pushing aside the fallen stones, he made his way into the room. Dazai was stunned. The detective immediately dropped the documents and took a step back, meeting you on his way.

— "What the hell are you?!"
