Rikka Takanashi is an 18 year old 3rd year in highschool but unlike other students, Rikka, used to have chunibyo. 6 months ago Rikka gave up her chunibyo for a stonger relationship with Yuuta, but when Rikka is suddenly transported to a new world she must figure out if staying out of chunibyo is a smart option or will becoming Wicked Lord Shingan once again bring her back home?
