The princess of the Royal Empire remains imprisoned in the Hellhorde dungeons, constantly enduring their insidious methods of inhumane interrogation—lavish meals, heartwarming companionship, and comforts too delightful to resist. As new rounds of unbearable torture continue to make her days in confinement better, every pleasant experience threatens to loosen her resolve and give the demons exactly what they want—no matter how useless the information she reveals may be.

As the commander of the Imperial Army's Third Legion, the Royal Empire's princess has led humanity to countless victories against the demonic Hellhorde. However, she has now been captured by the enemy and confined to the dungeons, with her sentient sword, Ex, as her only company. Due to her royal status, the princess knows invaluable secrets that would help the Hellhorde achieve dominance. To have her reveal all the information they need, the demons do not hesitate to subject the princess to the most vile forms of torture—that is, tempting her with delicious food, lasting friendships, adorable animals, and the most enjoyable experiences imaginable.

In a future where hip-hop reigns supreme, skilled rappers put on shows known as Phantom Lives. There they turn their powerful emotions into captivating illusions for their audiences through the usage of Phantometal—a material that reacts to the rapper's DNA to create the fantastic imagery. However, usage of Phantometal causes rappers to relive past traumas and painful memories in so-called Trap Reactions. Depending on the strength of the rapper's emotions, these reactions can be debilitating and even affect their psyche. After disappearing without a trace 10 years prior, the legendary CLUB Paradox mysteriously returns to announce the start of a new Phantom Live competition called Paradox Live. With 10 billion yen on the line, four established groups—BAE, The Cat's Whiskers, cozmez, and Akanyatsura—are invited to take center stage. Though wary of the strange circumstances, each of these groups have their own reasons for throwing themselves into the competition. Unfortunately, the path to glory may be more ruthless than they could imagine.

The Fourth Industrial Revolution has led to the development of cutting-edge technologies that have rapidly evolved the world. As a result, schools have begun incorporating these technologies into their curriculum, leaving behind the ways of the old. One such institution is the elite Yuyu Girls' Vocational High School, where both Serufu Yua and her childhood friend, Miku Purin Suride, have applied. Although the tech-savvy Purin is accepted to Yuyu High, the accident-prone Serufu is rejected and enters the traditional Gatagata Girls' High School instead, driving a wedge into their friendship. On her way to class one day, Serufu gets into a bike accident, and Rei Yasaku, a passerby who attends the same school, fixes her damaged bicycle. Serufu later finds out that Rei has a passion for old-fashioned crafts and is the head of the school's Do-It-Yourself (DIY) Club—which is in danger of closing due to a lack of members. Realizing that this may be her chance to repair her relationship with Purin, Serufu joins the club in hopes of creating projects that could bring them together once more. As the DIY Club welcomes new faces, Serufu learns to build not only handicrafts but also new friendships along the way!
