Humanity was caught at a precipice a decade ago when the first gates—portals linked with other dimensions that harbor monsters immune to conventional weaponry—emerged around the world. Alongside the appearance of the gates, various humans were transformed into hunters and bestowed superhuman abilities. Responsible for entering the gates and clearing the dungeons within, many hunters chose to form guilds to secure their livelihoods. Sung Jin-Woo is an E-rank hunter dubbed as the weakest hunter of all mankind. While exploring a supposedly safe dungeon, he and his party encounter an unusual tunnel leading to a deeper area. Enticed by the prospect of treasure, the group presses forward, only to be confronted with horrors beyond their imagination. Miraculously, Jin-Woo survives the incident and soon finds that he now has access to an interface visible only to him. This mysterious system promises him the power he has long dreamed of—but everything comes at a price.

As summer break comes to an end, Nishikata is stoked to try out his newest pranks and finally outdo his classmate Takagi once and for all. Despite his losing streak, he is slowly getting to know the unrelenting workings of her crafty mind. However, he soon realizes that Takagi's motivations behind her teasing may not be what he initially assumed. One thing is certain, though: each fun-filled day of strategizing and competing brings the two closer than ever.

In an Edo-era Japan lush with a variety of sword-fighting styles, Shichika Yasuri practices the most unique one: Kyotouryuu, a technique in which the user's own body is wielded as a blade. The enigmatic seventh head of the Kyotouryuu school, Shichika lives quietly in exile with his sister Nanami until one day—the wildly ambitious strategist Togame barges into their lives. Togame brazenly requests that Shichika help in her mission to collect twelve unique swords, known as the Deviant Blades, for the shogunate. Shichika accepts, interested in the girl herself rather than petty politics, and thus sets out on a journey. Standing in their way are the fierce wielders of these legendary weapons as well as other power-hungry entities who seek to thwart Togame's objective. In order to prevail against their enemies, the duo must become an unbreakable team as they forge ahead on a path of uncertainty and peril.
