A year has passed since the School Island incident, where four of the seven kings fought for their lives to stop the evil Colorless King; Silver King Yashiro Isana has gone missing.

Blue King Reisi Munakata summons Kuro to SCEPTER 4 to learn more about his recent encounter with JUNGLE, while Neko waits for her partner at HOMRA's home base.

Green King Nagare Hisui orders his two most powerful clansmen, Yukari Mishakuji and Sukuna Gojo, to attack the School Island where Kuro and Neko have set up base.

Silver King Yashiro Isana finally makes his return, forcing JUNGLE to fall back for the time being; reunited with his friends, Shiro reveals where he's been for the past year and his future plans for dealing with the Green Clan.

The Red, Blue and Silver Clans agree to form an alliance to stand against the Green Clan; things seem to go smoothly as the three clans work together to clear the streets of the Greens.

Shiro gathers SCEPTER 4 and HOMRA to inform them about the Green King's past and his ambition to release the Dresden Slates' power to the world.
