I Was Bitten Late at Night, and the Vampire School Beauty Forced Me to Awaken My Bloodline

A poor student works part-time and delivers takeout to a manor in a wealthy area late at night. He meets a beautiful school beauty whom he thinks about day and night, but she is a vampire... The school beauty pulled him in and wanted to use him as a snack. It was no use shouting at him, but she swallowed him in one gulp. Unexpectedly, before dying, he was forced to awaken the bloodline of the ancestral witch. The next second, the situation reversed, and the beautiful school belle changed from a hunter to a prey... Ouch ouch——!
