Liliana Vampaia is a sweet half-vampire, half-human on a quest to find a cure for her Otou-san who was cursed to live as a bat forever after breaking two rules in the vampire realm – marrying a human and staying exposed in direct sunlight without any sunblock.

Determined to remove the curse, Liliana finds herself in the human world for a way to save her Otou-san. However, finding a cure or someone who can help break the curse is difficult especially for a hikikomori vampire like Liliana.

Learning that the Internet has the ultimate power to connect people and creatures from all over the world, Liliana sets her heart on becoming a famous VTuber idol in order to reach as many hearts as possible. Upon becoming friends with them, she hopes that one of them knows a way to break the curse so that one day, she can run into Otou-san’s arms again.
