A Slime's Way of Playing Hero (Tensura x MHA)

It's been 456 years since the Great Tenma War. Since then, the wounds brought upon the Cardinal World have long since been healed, and peace was restored to the land. Tempest as a nation grew astronomically, both technologically and culturally.

As per usual, Rimuru was in his office, slaving away at his seemingly endless stacks of paperwork. With one pen in each hand, he was tearing through documents like never seen before. Eventually, however, he stopped, a slight frown appearing on his face.

"Nee, Ciel, I'm not sure what to do anymore. I accomplished what I wanted to do, my loftiest goals have been reached, but now I just feel.. Bored." He put down his pens, sighing as he slammed his head on his desk with a small bang.

Suddenly, there was a disturbance in the force. A faint ripple of energy permeated throughout the entirety of the Cardinal World and beyond. It was so faint, in fact, that only those with the most acute senses could possibly detect it. Take Rimuru, for instance.

"Ciel, did you feel that too?"

[[Yes. Master, it seems as if there was a spatial disturbance. The results of my analysis seem to be pointing to the fact that a portal has appeared deep within space.]]

'A portal? How odd,' Rimuru pondered with one hand on his chin.

[[Yes, Master. It is an intriguing sight indeed. Further analysis dictates that it might lead to a new world entirely. The chances of this being the case are 76.92317401-]]

Rimuru cut Ciel off with a wave of his hand. "Alright, alright, I get it. However.." He looked up in excitement, his expression doing little to betray his true thoughts. 'This is my chance! My chance to get away from this darned office!'

And so, he set off on a brand new adventure alongside his trusted Manas.
