It's Just Not My Night: Tale of a Fallen Vampire Queen manga volume 3 features story and art by Muchimaro.

FINAL VOLUME.

Manablue, once a legendary vampiress and Queen of the Night, lost pretty much all her powers and got stuck working at a convenience store on Earth. All kinds of shenanigans have gone down since then, but after regaining her powers of regeneration, Manablue finds herself with the weird problem of needing to dispose of her own dead body. Several of her own dead body, in fact. Luckily, she has her loyal minions and a long-suffering yakuza dude to help her get it done!

The cute and unnecessarily lewd adventures of one extra-unfortunate vampire reach their end in this hilarious concluding volume!
