"I promised I'll come back." After the Great Tenma War, the strongest being in existence, Rimuru Tempest, defeated the World-Destroying Dragon, Ivarage-the twisted reincarnation of Veldanava, the Creator God. Although the battle saved countless worlds, the price was his own life. With a smile, Rimuru made one final promise to the people of Tempest. "Don't destroy Tempest while I'm gone." His body dissolved into magicules, and his soul began another reincarnation. He awakens as Rimuru Tempest of the House of Tempest, a newborn child in the world of Attack on Titan. A world where Titans rule through fear. A world where freedom is merely an illusion. But this Rimuru isn't just any child. Hidden within the mysterious House of Tempest lies a forgotten bloodline dating back to the ancient Eldian Empire-a family that once inherited the Attack Titan, possessed royal blood, yet refused to kneel before kings, Titans, or destiny itself. Now living as a seemingly ordinary boy in the year 820, Rimuru has no intention of becoming a hero. At least... not yet. Guided by Ciel, recovering his former powers one step at a time, and surrounded by a family that values freedom above all else, Rimuru's new life begins long before the fall of Wall Maria. Will he change history? Or will history change him? Freedom is never given. It is chosen. ━━━━━━━━━━━━━━━━━━━━━━ Disclaimer That Time I Got Reincarnated as a Slime (Tensei Shitara Slime Datta Ken) is owned by Fuse.

"Ayanokoji Kiyotaka, a masterpiece of the fourth generation of the White Room and a high schooler of Japan's most prestigious school, is suddenly killed one day by unnatural causes, sending his soul to the afterlife where he encounters a mysterious goddess."

What if Ayanokoji was reincarnated in a world of magic?

Orario, the city of adventurers' paradise. Everyone who comes there has their own ambitions. Some want to become strong, some dream of restoring the pride of their race, and others aspire to become rich and famous. Among them are those who can be considered naive or foolish-those who wish to become Heroes. Of course, Emiya Shirou is one of the foolish ones.

Long story short, my attempt to practice writing lemon instead of writing my main stories. All of them will be Rimuru x Female Character. Please read the tags I will be adding per chapter. No interest in collaborating with illustrators or comic artists. Tensura isn't mine, all credits to Fuse.

After leaving behind his godlike life, Rimuru Tempest is reborn into the glittering yet ruthless world of Oshi no Ko, where he slowly climbs the entertainment industry while unknowingly crossing paths with the radiant Ai Hoshino.
