my hero academia: reincarnated as Rimuru ("very original")

oh no! [Insert name here] has just died! already content with his death he awaited whatever is beyond death's door maybe he'll encounter the pearly gates or find the deepest pits of hell, however suddenly he was hit with a curve ball Reincarnation! Reborn anew [NAME] was lost as to his purpose however he soon heard his new name and threw it all away. "Rimuru Tempest" Im going to have so much fun! Unfortunately Rimuru is still a baby, so the most he could do is play with blocks. however good news! Rimuru has reincarnated into the MHA world! Multiversal character inside a low level world how fun! Wait... why are my abilities so a weak? dont tell me.... Nononono No wait please! Don't do this to me! (WARNING: Rimuru in this Novel is heavily nerfed, don't expect a power fantasy. This story doesn't take itself very seriously. I am a rookie writer, I cant make miracles happen.) PSST... It's no harem.... but you haven't heard it from me... shush shush ******** (I've never tried writing in my whole life this idea just popped into my mind and hasn't let got) not my characters or story I do not own any of the property used in this story. all of the content in this story is very much unoriginal.
