This is a trope page for a light novel about a pair of high school boys who end up being summoned by an ancient map and are forced to exterminate a vampire haunting a castle, only to be turned on by the owner. Things only get worse from then on.
- Call a Rabbit a "Smeerp": Summoned individuals are called Dilfrant, which apparently was the name of the first such person.
- Can't Hold His Liquor: Played straight here due to both protagonists being underage.

- Pint-Sized Powerhouse: Valkyria's little sister, Culaya, is able to send grown men flying during a hostage situation.
- World of Buxom: It's rare for any female characters to "rank" below a C.
