Alzi had a promising future. At seventeen, the Goddesses blessed her with a life affinity—a rarity for commoners in a small village; a few days before the class-choosing ceremony, her Mother gets sick. After using her little mana to keep her alive, she runs to the capital to find a true healer. With no money, she sells herself into slavery for a decade. The decade is almost up, but she has been turned into a broodmare for the nobles and faces a sale to keep her enslavement going.

“Hey, have you ever heard of the lunatic roaming around the tower?”“Are you kidding me? Who haven't heard of him yet!?”“Hey hey, are you talking about... that person?”Interesting news travels even faster than light, especially regarding the mysterious figure that everyone in the Ethereal Tower is curious about, the lunatic ascender whom thoughts and deeds are so off-place that even the greatest among them just couldn't grasp his intent, almost as if he is ascending a completely different tower than them.While everyone in the tower talks about the lunatic who lurks on each tower's floor more than he is supposed to, the person they are talking about just goes on his merry way to collecting treasures he wants, and while the world is talking about him.“Come on, give me some luck, maybe roll the hundred times multiplier again...”He's sitting while rubbing his palm together, gambling on something that will make everyone faint.

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.
