After dying, Hong Chen, known as the "Blood Fiend," transmigrates into the world of Call of the Night.
With an extraordinary mastery of blood, Hong Chen decides to cosplay as a vampire. After all, he's practically a vampire already.
All right, let the sweet romance of Nazuna Nanakusa and Ko Yamori heal my wounded heart...
A green-haired vampire girl and a blue-haired high school girl wearing a screw-shaped hat?
Wait, where did this black-mist vengeful spirit come from? And why does that golden-tailed fox girl look so familiar?
And what's with those followers over there tinkering with what is clearly some kind of very suspicious summoning circle???
"I'll stand alone against the darkness that never appeared in the original! I'll make sure all those heartbreakers and NTR bastards die by my hand!!!"
This is the story of a romance warrior protecting the sweet everyday love between Nazuna Nanakusa and Ko Yamori in an even darker, stitched-together parallel world.
"Actually, if I could, I'd like to have a sweet romance of my own, too."
Current worldline: Call of the Night as the main setting, plus Actually, I Am... and The Helpful Fox Senko-san, with some original elements.
