It's hard work taking it slow...

My life on Earth was miserable-nothing but commuting, work, and sleep until my body gave out due to the stress. So when I got a second chance in another world, I swore I'd never do that to myself again. I'd just kill a few slimes to make a living, maybe experiment with a little potion-brewing, help a few people along the way...

...But it turns out, 300 years of killing slimes can make you one of the most powerful beings in the world! And when the truth gets out, I'm sure adventure won't be far behind...

What's gonna happen to my peaceful life now?!
