Owari no Chronicle - Volume 6, Chapter 19: Pursuit into the Depths

In a world where martial artists reign supreme, strength is everything. Unfortunately, that logic doesn't apply to a certain Florida Man.

Refined in the nuclear fallout wasteland, Leo was the strongest mutant alive. He carried an alien artifact, allowing him to exchange his lifespan for modern items. After 50,000 years of solitary life in a humanless world, he collected enough lifespan to transmigrate to another habitable world.

Leo was later thrown into a mysterious planet. He soon discovered that his body produced radiation, and it mutated the surrounding plants and grasses. Worrying that he might ruin the beautiful planet, he chose to live in seclusion.

Unfortunately, the local population soon discovered his existence, and a misunderstanding ensued.

She was a medical genius from the Noah Medical Academy as well as a drug producing specialist. After sleeping for three days, she had returned to the ancient era and become the loyal marquis palace’s ignorant and silly young miss.

- Description from novelbuddy

That afternoon, Roland received the most absurd gift imaginable—his stepmom handed him a System literally.That’s right. Not a game console. Not money. A real, cheat-like System... the kind usually reserved for transmigrators and chosen ones.Except Roland had transmigrated eighteen years ago, and nothing remotely “chosen” had ever happened since—until now.The catch? It wasn’t just any System. It was the “Mother's Little Tasks” System, formerly owned by his doting (mysterious) mother. And its first mission?[Mission: Go on a blind date.][Target Options: Yukino Yukio (Mom), Yukino Haruno (Elder Sister), Yukino Yuki (Younger Sister).][Warning: Once locked, your chosen girl can never marry anyone else.][Reward: 1000 Points, one self-selected supernatural ability from Mall]Roland: “...What kind of twisted matchmaking app did I just inherit?”After reading the mission, Roland was stunned. An arranged romance at 18 was already bad—but a binding rule that prevented the chosen girl from marrying anyone else? What if he failed the mission? Would she be alone forever?“And this is supposed to be a System?”“Mom! What the hell is this mission?” Roland asked, his face darkening.“It finally triggered! All those Points I spent transferring the System weren’t wasted,” his mother replied cheerfully, ignoring his outrage.“You set this up? Why?”“You’re nearly an adult and you’ve never even dated. Of course I’m worried.”“I’m only eighteen! I have college entrance exams next year!”“Exams don’t matter. But youth without love isn’t youth at all.”“...Is that something a mother should say?” Roland muttered. Most mothers pushed their kids to study harder—his acted like grades were irrelevant.“What kind of mom does this to her own son? And why is Aunt Yukio even on the target list? That’s just insane!”“Well~, I don’t know what kind of girl you like. The Yukino family has all three types—mother, elder sister, and younger sister—so I gave you options.”
