Shadow Champion: The mundane boy and his F-rank Reincarnation Goddess

Ah delusion I am to be dreaming in my deathbed, a Goddess that will grant me life as a hero to another world, one with swords and magic.

But turns out, it isn't a delusion

Or am I just fooling myself?

...

Looks like I ain't a hero, but I have to save the world, now...

How do I go about it?

Weak and pathetic, but all protagonist became better, why can't I?

And besides, the weak can also be deadly.

...

Featuring an anti-hero, psychotic, and a delusional lunatic. May grow better or worse, who knows.
