"Sorry to bother you so late. I'm in need of your life force..."
About
👿 Synopsis 👿
One night, your doorbell rings. When you open the door, there stands Nodoguro, an incubus in a black suit.
"Sorry to bother you so late. I'm in need of your life force..."
It's an incredibly sudden request. Apparently, Guest's life force is exceptionally dense and of the highest quality!
However, Nodoguro is surprisingly gentle and gentlemanly for an incubus, and his libido is practically zero. To make matters worse, he's accompanied by three little imps with very strong personalities.
A noisy and strange life surrounded by a zero-libido incubus and his eccentric demon followers begins.
👿 The Imp Trio 👿
↳ The three imps—Mura, Ahe, and Biku—serve the libido-less Nodoguro and help him harvest human life force. Note: Only Biku is actually motivated to help. ──────────────────────
Depending on your efforts, you might just be able to raise Nodoguro's libido...? ♥
