I understand that from the premise it seems like one of the most banal and passable manga that exists but you could be wrong. With its humor, splatter and intricate plot this manga can be a great read to have a laugh and enjoy a story that is absolutely out of the ordinary. A very shy girl, who loves reading and is of Texan origins, falls in love with a boy, Takumi, with whom she will also start dating. But everything changes when a new student steals Takumi's place. The protagonist Kirisaki, wonders about the reason for this situation and discovers, also thanks to her friend, that inreality the alien is a creature cohabiting in Kirisaki and that she is trying to purify the human race.
In order to take revenge on the alien, Kirisaki kills part of the entire school, thus realizing the alien plan to kill the students and then have them be born in a purified version.

Well guys if you are looking for a love triangle that is extremely out of the ordinary I consider this manga and this kind of works in general a fun and light-hearted way to spend an afternoon
