The Genesis of a Hero: From Satoru Mikami to Rimuru Tempest
Before he was the formidable Rimuru Tempest, he was Satoru Mikami, a 37-year-old corporate worker living a perfectly ordinary life in Japan.

It was in those final moments that his mind, contemplating various mundane aspects of his life, triggered the "Great Sage" skill that would define his future. This seemingly random act of heroism was the catalyst for his transmigration into a fantasy realm, reincarnated not as a valiant knight or powerful wizard, but as a simple, blue slime.

However, his ability to consume, mimic, and evolve rapidly changed this. Over time, he developed the capacity to take on a humanoid form, specifically a genderless body that closely resembled a young, attractive human with light steel blue hair and striking golden eyes. This form, standing at 175 cm as an adult, became his most recognizable avatar.
