Millenia has passed the defeat of Levargè, Rimuru Tempest has developed Tempest into a nation that doesn't even need him. Upon being bored and lost in thought, he no longer had a direction or a purpose, all he had was 'regret'. Upon this revelation, he and Ciel will Warp into the past as a form of reconciliation. Will he take the most optimised path or the relaxed path to success? (This is a fanfiction and I do not any of the copyright as the IP is owned by Fuze-sensei. This is merely a fanfic for hobby purposes) A/N: Slow updates, don't expect 1 chapter a week thought that's a target and aiming higher is always better.

As autumn graces the land of Tempest, the village comes alive with vibrant hues and the promise of a bountiful harvest. Rimuru and his companions come together to celebrate the simple joys of life with a heartwarming festival. From Shion's ambitious cooking escapades to Velgrynd's elegant contributions, and Milim's playful antics to Veldora's tall tales, every moment is filled with laughter, connection, and gratitude. In the cozy embrace of the season, the bonds of friendship and family grow stronger, reminding everyone of the beauty found in peace and togetherness. Join the cast of Tensura in this heartfelt slice-of-life story as they share moments of joy, reflection, and camaraderie under the golden glow of autumn.

Remake... Nothing more, character don't belong to me beside the occ Like before story about Rimuru and his adventure, different race and scenario. I'll also change the story a little and correct some small spelling mistake. By the way none of the manga/anime/Ln and more are mine but to their respective author.

A bored Rimuru Tempest accompanies Diablo when he goes to meet with an old friend in the Netherworld. What will happen when he meets an out-of-place human boy who piques his interest? (Tensei Shitara Slime Datta Ken and Mairimashita Iruma-kun crossover)

This is going to be filled with the one-shots I write and any reaction chapters I make, the reaction chapters will have a role in the story of my stories in the future. This is wholly for fun and to gauge your interest as readers. Any stories received well have a chance in the future to gain a full story beyond this space. (This will have a ton of ships because of the one-shots but most prominent will be in tags. I will add more as they get more stories.) Think of this like this Ciel is messing with Rimuru and making the cast of characters in different places watch his experiences and these experiences may have effects in literal stories. I will also do reactions from other crossovers casts for a use of adding to the character and thought process of the cast. I hope you enjoy the reactions and the One-shots. Reactions will come randomly and One-shots will in a sense follow the same pattern but I will more than likely leave author notes in my other stories about what is to come as usual.
