K: SEVEN STORIES "R:B - BLAZE -"

It is the beginning of December. Anna Kushina’s birthday is coming up, so the boys of HOMRA decide to celebrate by preparing a surprise party for their little princess. Tatara Totsuka, the only clansman capable of keeping the destructive power of the Red King, Mikoto Souh, in check wants to do something special and film a video for Anna's birthday. Meanwhile, the new Colorless King sets his plan to devour the other kings in motion...

Over a decade ago, a clash between the Red King Genji Kagutsu and Blue King Jin Habari led to what would later become known as the Kagutsu Incident—a catastrophic disaster that wiped out a portion of eastern Japan, claiming over 700,000 lives, including that of the two kings. Years later, Goki Zenjo, former right-hand man to Jin Habari and a survivor of the incident, returns to work for SCEPTER 4, now under the command of Reisi Munakata, the new Blue King. However, Zenjo is still having difficulties accepting Munakata as his new king. One day, Munakata requests that Zenjo personally train a young new recruit named Takeru Kusuhara, insisting that his teachings will become crucial to the future of SCEPTER 4.

Sukuna Gojo is a boy who ran away from his wealthy home after becoming disgusted by his controlling parents. Since then, he’s been surviving alone on the streets using an SNS app called JUNGLE, which grants its user unnatural power and abilities. One day, Sukuna comes into contact with the founder of JUNGLE, the Green King Nagare Hisui. Wanting to learn more about the mysterious Green King, Sukuna decides to climb up the ranks of JUNGLE so that he can meet Hisui in person. But in order to reach the highest rank, Sukuna must defeat the most powerful user in JUNGLE.

Adolf K. Weismann is sharing a peaceful meal with his loved ones, while Misaki Yata is having a blast hanging out with his HOMRA buddies.
