MTL - Two-Faced Husband, Have Some Decency! - ~ 030, you are with You, I am with you.

Haruto Hayase was a normal high school boy in his third year, living a quiet life until his younger sister, Haruka Hayase, joined the same school. Haruka’s beauty and charm made her the center of attention, quickly becoming the school’s prima donna. But when a notorious gang leader set his sights on her, he did everything in his power to protect her—only to fail tragically. Haruka was brutally assaulted and tortured, and Haruto himself suffered an agonizing death. However, in a twist of fate, Haruto is given a second chance, waking up a year before the events that shattered his life. Armed with the mysterious ‘Debauchery System Slave’, he vows to exact revenge on those responsible. This time, he will use his newfound powers of the system and charm to seduce the loved ones of his enemies. From their mothers, sisters, and lovers to their closest friends, Haruto will make them his. His enemies will suffer as he steals what they hold dearest, ensuring their downfall in the most devastating way possible.

This is a cliché story about two young people saving the world.

Long ago a great calamity struck the earth, destroying much of it and merging what remained with pieces of other worlds.

With these worlds came Aether, a new form of energy that can allow one to transcend the bounds of normal mortality and human limitations.

In a world where humans absorb the essence of aether beasts to gain power, Aiden Hawke joins the class of humans known as arcanists, people who defeat aether beasts and absorb their essence into cores they forge within themselves, and who infuse themselves with the aether that permeates the world around them to increase the power of their body and mind.

However, unlike most, Aiden will find that he holds a unique gift and that his journey as an arcanist will not be so simple.

Caelen died doing what he loved most: playing survival games non-stop like a sleep-deprived goblin. Unfortunately, dying in your chair from gaming overload isn’t exactly what you’d call a dignified exit. Even God laughed at him.But lucky for Caelen, or maybe unlucky, he gets a second chance in the world of his favorite survival game. It’s a brutal fantasy realm full of monsters, magic, swords… and absolutely zero indoor plumbing.Armed with only a stone pickaxe, a limited-use “Google Brain” search skill, and the stubbornness of a man who once built a Minecraft mansion out of dirt, Caelen sets out to survive. But surviving isn’t enough he wants to upgrade the world. Electricity? Toilets? Toasted bread? Why not all three?As he fends off nighttime horrors, awkwardly crafts furniture, and tries to avoid becoming monster chow, Caelen has one mission: bring modern convenience to a medieval world, one ridiculous invention at a time.And maybe, just maybe… not die again in a chair.[System Notes:No Ntr, No Yuri(gl), No Yaoi(bl)]
