As a single mother, I support my daughter by selling my blood.

After her kingdom is destroyed, Sylvia drifts into the Demon Realm and picks up a baby girl.

In order to raise her in the Demon Realm, Sylvia is forced to—

Sell her blood to the vampire princess.
Sell her emotions to a succubus.
Sell her soul to a demon.
Sell her body to the Demon King.
…

Sylvia sells everything just to raise her daughter to adulthood.
At last, she waits until her child grows up—

But by then, she herself is already riddled with scars.
