Good news: He transmigrated into the world of a yuri galgame, and he even became the only male character with handsome official character art.

Bad news: the character he transmigrated into was a villain maliciously designed by the developers—Greg Sass, a character who has as many as 1,380 death CGs in the original game.

And so, to escape every possible death ending, he had no choice but to enter an equally dangerous dungeon.

With the cheat ability he had just obtained, he planned to survive there until the protagonist cleared the grand finale, then return to the surface and welcome a happy, beautiful life.
