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)

(Ayanokoji x Kushida Although romance is not a prominent aspect of the story) Instead of emotionless koji who had a monotonous face; we have an expressive koji who seems to smile and show excitement around his peers. Although, no one but him and his significant other seem to know that it's all an act, it will stay an act and it will forever be one. Started: Friday 28th July 2023 Finished:
