Time to go Berserk in Another World!

This story is about a young boy who constantly get's bullied and avoided by his classmates, basically treated like trash.

One day, he and his class mysteriously get's transported into another world, as the summoned heroes of legend. As they wake up, they are told that they are the only ones able to save humanity from the Demon Lord Astaroth and his army.

At first it seems like it's the typical happy Isekai story, but then suddenly their teacher get's executed?! They are forced to fight?! They are treated like consumables, like tools.
Then, as it was Yato's turn to tell his class, it turns out that he is a Berserker, a class that only demons and mindless magical beasts possess.

He is captured and thrown into the dungeon.
All of his classmates do nothing to defend him, some even dare to smile at him,
holding back their laughter. He shall be tortured and executed at the dawn of the next day.
He accepts a demon's deal and is freed, now fighting his way to the outside.

This is his journey, the journey for a new try, a fresh start, a mysterious adventure in an amazing new world, and his journey to become strong enough for his absolute revenge on those who have betrayed and thrown him away!
