The supermarket is an important building in any city, for they provide a convenient way to purchase a variety of food in a family-friendly, safe environment. However, these stores changes in the blink of an eye once the unsold bento boxes go on their nightly half-off sales! War breaks out and friends become foes as each person fights for honor, pride, and dinner. There are no longer any people in these supermarkets, only Wolves and Dogs⁠—winners and losers. High schooler You Satou is painfully introduced to these battles after unknowingly stumbling into the war zone, but instead of choosing to avoid these nightly fights, he wants to join in. After seeing Satou's lack of fighting skills, upperclassman and Wolf Sen Yarizui invites him and Hana Oshiroi, a girl who enjoys spectating the brawls, to join her Half-Priced Food Lovers Club to show them the distinction between the Dogs and the Wolves. Together, they learn what it truly means to fight for your food.

Fifty years ago, horrific creatures dubbed as the enemies of humanity suddenly appeared around the world. To combat these threats, teenagers gifted with supernatural abilities called Talents—such as pyrokinesis and time travel—hone their powers at an academy on a secluded island. Nanao Nakajima, however, is quite different from the others on the island: he has no Talent. With many Talented teenagers around him, Nanao is often a target for bullying, but even so, he still strives to complete his training. Soon after, two transfer students, the mysterious Kyouya Onodera and the mind-reading Nana Hiiragi, join the class. But just as everyone starts blending as comrades-in-arms, mysterious disappearances begin to threaten the class's entire foundation.

Seiken Tsukai no World Break takes place at Akane Private Academy where students who possess memories of their previous lives are being trained to use Ancestral Arts so that they can serve as defenders against monsters, called Metaphysicals, who randomly attack. Known as saviors, the students are broken up into two categories: the kurogane who are able to use their prana to summon offensive weapons and the kuroma who are able to use magic. The story begins six months prior to the major climax of the series during the opening ceremonies on the first day of the school year. After the ceremony is over, the main character, Moroha Haimura, meets a girl named Satsuki Ranjou who reveals that she was Moroha's little sister in a past life where Moroha was a heroic prince capable of slaying entire armies with his sword skills. Soon afterwards he meets another girl, Shizuno Urushibara, who eventually reveals that she also knew Moroha in an entirely different past life where he was a dark lord capable of using destructive magic but saved her from a life of slavery. Can those whose minds live in both the present and the past truly reach a bright future? Delve into the complex world of Seiken Tsukai no World Break to find out!

Even though they shared the same bus every morning and sat next to each other in class, Ayaka Kagari, the Princess of Tougetsu High School, was nothing more than an unreachable idol for Honoka Takamiya.

Everything seemed perfectly normal until, one day, Honoka is attacked out of the blue by a mysterious witch. To his surprise, Ayaka saves his life, revealing herself to be a fire witch on a covert mission to protect Honoka. From that fateful day, the ordinary life of Honoka is turned upside down as he is thrown into the war between the Workshop Witches, who strive to protect the citizens, and the Tower Witches, who desire to steal a power hidden within him.
