Following their heroic efforts at Walter Park, the students of the misfit class return to Babyls Demon School after their summer vacation. What awaits them is not only adoration and admiration but also the shocking revelation that, in order to stay in the luxurious Royal One classroom, the entire class must be promoted to Dalet rank before entering the second year. As the Harvest and Music Festivals are right around the corner, there seem to be ample opportunities to rank up. Doing so will not be simple, however, as no class thus far has managed to accomplish such a feat. Hoping to give the misfit class a chance to achieve the improbable, the school appoints special tutors to aid in confronting the challenges that lie ahead. With his sights set beyond Dalet, Iruma Suzuki decides to take strides toward the goal of ranking up, starting with gaining acknowledgement from his special tutor: the short-tempered and selfish Bachiko Barbatos.

He begins to enjoy the life of parenthood— experiencing the trials that come with raising a child and coping with the heartache he feels whenever his busy lifestyle as an adventurer parts him from her. Although work and life as a new parent become reassuring constants for Dale, the mysteries surrounding the girl remain. Why was Latina alone in the forest, and why does she harbor the symbol of a criminal? At the same time, Latina also begins to learn about the world and herself as she adjusts to her new life with Dale. [Written by MAL Rewrite]

At Kaimei High School there is a special club dedicated to helping others known as the SKET Brigade. The brains of the group is Kazuyoshi "Switch" Usui, a tech-savvy otaku who speaks through speech synthesis software, while the brawn is provided by Hime "Himeko" Onizuka, the hockey stick-wielding girl once known as "Onihime." And last but not least, their leader is Yuusuke "Bossun" Fujisaki, whose latent ability is evoked by his goggles, allowing him to summon the awesome power of extraordinary concentration. However, most of the school only know them as the club that handles odd jobs. Many of their days are spent in the clubroom slacking off, but when there is something to be done, they give their all to help others—usually in sincere, but unintentionally hilarious, ways. The SKET Brigade do all they can to provide support, kindness, encouragement, and troubleshooting to any students crazy enough to ask for their services. [Written by MAL Rewrite]
