Karin is a cute little girl who also happens to be a vampire... with a twist. Once a month, she experiences intense bleeding from her nose - we're talking gushers! In other words, she's a vamp with blood to spare, so rather than stealing blood from humans she actually gives her blood to them. If done right, this can be an extremely positive experience that benefits the "victim" as much as the vampire. The problem is that Karin never seems to do things right!

For once, Karin's life seems to be going in the right direction. She and Kenta have declared their love for each another, and Karin has finally met another vampire who has a similar blood problem. But will Karin's train of good luck become derailed with the return of her grandmother, lda Marker? What will Elda do when she finds out Karin's not a normal vampire?

As Karin, our favorite chibi vampire, deals with the newly revealed defects of her own body and its effect on her relationship with Kenta, Anju is facing her own set of problems.

And when the final twist is revealed, Karin's life will be forever changed in the concluding volume of Chibi Vampire!

Kenta sees Karin every day at both work and school, so each day serves as a reminder that something about the girl with the oft-bloody nose just isn't right. He's suspicious, and he's not exactly subtle about it. Fearing that he might discover her secret, Karin decides to kill this potential problem with kindness, going out of her way to do all kinds of nice things for him. However, when Kenta catches her "feeding" yet again, the gig is up.

Karin is finally getting over her blood issue with Kenta, and with Kenta devoting all of his time to her, she's living the good life. But her classmates are starting to take notice... Meanwhile, Ren, her brother, has his eyes on Kenta's mom. This could cause even more problems than all the new popularity! What can Karin do to stop her brother from hunting down his new prey?

Karin's grandmother is in town, and Elda Marker is no silver-haired, cookie-baking matriarch.

So how can Karin possibly tell her about her new human almost-sorta-not-quite-boyfriend?

Karin's crush of Kenta may be finally be revealed, but things take a turn when Kenta's mom seeks the whereabouts of Kenta and Karin with the assistance of a detective. A case of mistaken identity causes Karin's most explosive nose bleed ever! Karin's crush continues - but now as a forbidden one.

With Kenta discovering the true reason behind Karin's increase in blood when she's around him, their relationship shatters as they struggle to deal with the thought of losing the one they love. Meanwhile, what secrets in the past explain Kenta's hatred of his father? Will the two of them finally make up and bring happiness to the whole family?
