- Description from Novelupdates

Mysterious gates appeared all around the world a few decades ago. Beings emerged from the gates and brought disaster upon humanity. Humanity called them Demon Spirits. It wasn’t until the advent of Demon Suits and Demon Suiters that humans stood a fighting chance.For some perplexing reason, the world’s number one Demon Suiter, Li “God” Xiu abandons his identity to start over again as a newbie trial-taker. He enters the gates to participate in all sorts of trials, in a bid to seek out the reason that enticed his best friend into becoming a trial-taker.These trials weren't the run-of-the-mill dungeons, ranging from game sports (soccer, basketball, baseball, etc) to athletics. Just as fortune favors the brave, what would Li Xiu obtain on his quest?“Are you telling me he’s a greenhorn?” the other trial-takers frustratingly ask while watching Li Xiu's feats that prove why he's the number one Demon Suiter.

Callius von Jervain.

A character who dies no matter what he does. A character who falls into a forced choice route where he can only die, no matter his choices up to that point. However, there is a single route where the character can live and play the game.

And I have to carve out that route somehow.

Because I’ve become Callius von Jervain in the game.
