- Description from novelbuddy

After his parents died, Alex Roth had a plan: become a wizard. Through hard work, he was accepted into the world’s greatest university of wizardry—but fate had another plan.

On his eighteenth, he is marked as one of his kingdom’s five Heroes, chosen to fight the land’s great enemy. But his brand is 'The Fool', worst of the marks.

Rather than die or serve the other Heroes like Fools in the past, he packs up his little sister, his childhood friend and her cerberus, then flees for the university in hope of refuge, magic and to unravel the truth about his land’s evil.

There’s one small problem: The Mark tries to ruin magic while enhancing skills outside of divinity, combat and spellcraft.…

…that is, unless he can learn to exploit the hell out of it.

Samuel, a high schooler, got summoned with his classmates to another world as prophesied heroes. He expected glory, adventure, and a chance to save a kingdom. But those hopes were shattered when he discovered the truth, they were sacrifices, the gods who summoned them are no saviors, but monsters that feed on human souls. Among the victims is his little sister, dragged into the summoning by accident while she was delivering his lunch. Betrayed and marked for sacrifice, Samuel survives andmade a deal with (Arithmos) the God of war, with its power, he now vows to destroy every god and declares to take everything from them.
