A 37-year-old nice guy suddenly dies on the street, a victim of a random stabbing.

When he regains consciousness and checks his body, he finds he's become a slime!

"Huh? ...Huh? Why am I a slime?!" he cries, yet he still enjoys his everyday life as a slime.

His abilities grow, and his minions multiply. Perhaps he'll even aim to become a Demon Lord someday?

This is the otherworld slime life of such a naturally oblivious, slightly off-kilter protagonist.
