One day, Tanaka Tomoyuki and his classmates are summoned to another world. Each of them have been chosen by a god, and is tasked (against their will) to participate in a free-style tournament to fight against each other. Gods from all over the world, originating from different pantheons, have sent their representative heroes to a world where mythological monsters roam outside contemporary human cities. However, Tomoyuki's abilities turn out to be below average during the day. Viewed as useless, he was betrayed and used as bait for monsters in order for his classmates to escape. Abandoned and left to die, Tomoyuki survives and vows revenge on all those who betrayed him.

As the title says, this is the most cliched and badly written 異世界 (isekai) story ever. I kid you not. Imagine the cringeworthy cliches of ありふれた職業で世界最強 (Arifureta Shokugyou de Sekai Saikyou) and 捨てられた勇者の英雄譚 (Suterareta Yuusha no Eiyuutan or Tale of the Forsaken Hero) jumbled into a huge mess. Then add a terribly developed protagonist with no characterization and is just about the most stereotypical shounen character ever. Don't forget that he's surrounded by a cast of, if possible, even more one-dimensional and cardboard characters with no reasons or logic to their almost non-existent motives.

Well, please don't expect anything decent from the worst writer in the universe (not just in this world but also all the 異世界 isekai out there). Yes, I am that bad. I can guarantee you that you will not find a worse writer on Royal Road Legends (or even the entire Internet) than me. You've been warned.
