Tsunrize ~Tsundere Akuyaku Reijou Liselotte to Jikkyou no Endo-kun to Kaisetsu no Kobayashi-san~

Originally serialized as a light novel series written by Suzu Enoshima and illustrated by Eihi, the story began on the user-generated publishing platform Shōsetsuka ni Narō in 2018. It was subsequently acquired for print publication by Kadokawa Books, blending elements of the popular villainess subgenre with a meta-fictional twist in which the protagonists observe and provide commentary on the narrative through a magical connection to the characters.

The design of the series centers on the interplay between the fictional world of a video game and the external reality of the characters interacting with it. The illustrations by Eihi were praised for capturing the nuanced, dual nature of the titular Liselotte, whose external coldness masks an internal vulnerability that the primary characters strive to protect. The series received significant acclaim for its lighthearted humor and character growth, leading to a manga adaptation and a television anime production that expanded its reach to a broader international audience.
