I Run Dungeons in Another World

I have regretted it countless times, and I have also been glad countless times that I opened the forbidden door.

I taste the fear of the unknown, dissect the truth of the world, sink into the world of madmen, and keep watch over the soul I once had.

They always say I've gone mad. It doesn't matter. As long as I find her, my younger sister, then everything meaningless will become meaningful beyond measure!
