The Greatest Demon Lord Is Reborn as a Typical Nobody

Due to the isolation caused by his strength, the Demon Lord Varvatos longed for a normal life, and after several thousand years he reincarnated as the villager, Ard Meteor. His dream is to forge bonds of friendship with other humans. However, even after turning 10 he still had yet to achieve his goal. During that time he has a fateful encounter with a young girl fighting monsters in the forest.

Though he joined the magic academy, what awaited him was far from a normal life. Without realizing it Ard had already grown famous and he was quickly put on a pedestal by his peers. Then there was another problem within his class - the young girl, Ginny, a succubus, was being abused by Elraldo, a noble's son. Ireena then intervenes and Elraldo insults her. When Ard demands an apology, he is challenged to a duel instead.

The Headmaster begs Ard to participate in the upcoming battle event, and he struggles to decide since the risk is great whether he accepts or refuses. During that time Ginny invites him out on a date. Ireena butts in, but Ginny quickly approves her coming too. Ireena tries to be even more considerate after that, so Ginny speaks of her true ambition. Then on the day of their date, the three run into a suspicious group of people.

Ireena finds herself constantly irritated at Ard's popularity. While Ard is trying to think of a way to soothe her, Ginny appears before him in an enticing outfit. While Ginny makes her approach using her Charming Evil Eye, Ireena also presses him with a bold outfit of her own. The two are about to explode at each other over Ard and they nearly start a duel when...?!

Elzard is planning to use Ireena as a sacrifice to revive the evil gods and destroy the world. Yet why was Ireena chosen as a sacrifice? Ard appears before Elzard with new weapons in hand to rescue Ireena as Demons stand in his way. When Ireena's hidden secret is revealed, how will Ard react...?

The Demon Lord's companion, Sylphy, reappears in the modern world after several thousand years. A masked man tells Sylphy where she can find the Demon Lord and she... Meanwhile, the Magic Academy is preparing for its school festival, and Ard is asked to perform in a play in lieu of their Sword King Battle Tournament while also dealing with a threat to cancel the festival. Ard and the others start discussing the play when they're interrupted by a huge commotion at the school.
