Mikoto, the second son, is calm and collected, but he has a soft spot for his younger brother Minato, whom he adores and thinks is cute. Minato, the third son, is energetic and adores his brothers, but he is clumsy and awkward. Gakuto, the fourth son, is a studious and mature first-grader who is often referred to as a wise man. The manga depicts the four brothers' daily lives as they navigate their family, school, and community. (Source: MAL News)

Losing their war against Heaven's angel army, the demons of Hell are on the cusp of collapse. As a last ditch attempt to turn the tides of the war, the demons send Akutsu Masatora to the mortal plane on Earth to save their homeland from the angels. Disguising himself as a high school student, Akutsu seeks to recruit someone with the capability to lead the demons to victory. Akutsu does not have to look far: among his classmates is the magnificent Lily Amane, a transfer student who seems like the perfect candidate for Akutsu's plans. But as luck would have it, Lily is one of the very angels that Akutsu is meant to be fighting against, and his attempt to recruit her might end up being the biggest blunder in the failing war. Worse yet, Akutsu may fall in love with his own worst enemy.

In their last year of middle school, the five band members of CRYCHIC went their separate ways after an unpleasant disbandment. Each wrestling with their own regrets, the girls enrolled in different high schools, hoping never to hear from one another again. Meanwhile, Anon Chihaya transfers to Haneoka Girls' Academy in the middle of the school year. As most students play in a band as a hobby, Anon desires to fit in and spends her first days trying to recruit members for her own band, envisioning herself as the group's vocalist. She befriends Tomori Takamatsu, a shy girl who seems interested but hesitant about joining. As it turns out, Tomori used to be part of CRYCHIC, an experience that has scarred her deeply. Through Tomori, Anon meets Taki Shiina and Soyo Nagasaki, both former members of the same band. Although Taki detests the idea of playing with Anon, Soyo is delighted to help her out. Now with Soyo by her side, Anon's dream of forming a band is within reach—if only she could find a few more members.
