I've been reincarnated again!? (Slime/Mairimashita)

this is a crossover between Mairimashita! Iruma-kun and That Time I Got Reincarnated As A Slime!

Rimuru Tempest (currently known as Iruma Suzuki) was reincarnated, again, as Iruma Suzuki, a kind-hearted kid that couldn't say no for the sake of his life. He is the founder and King of the Jura Tempest Federation in Jura Forest. He is one of the Demon Lords of the Octagram.

Until one day, he was transported into a different world with a shitty parents, who sold him into a demon who soon became his grandfather???

What the hell is going on!?!?
