A person spotted Noir up in the northern reaches of Yodaka. Lag is ordered by the Bee-Hive Master Largo Lloyd to find out what Noir is up to, and he heads there with Niche and Steak. There he discovers a shell of what looks like a giant gaichuu, as well as a used cartridge which Noir left behind. Lag shoots his own shindan into the cartridge!

Lag visits the town of Blue Notes Blues, steeped in the legend of the Maka, the mysterious creature deeply connected to Niche. The people in town witnessed someone like Noir heading into a cave, however the Mayor, Khari Tonov, tells them that cave is where the Maka lives and is dangerous, and entry is forbidden no matter who it may be. But despite this, at Niche's suggestion, Lag heads toward the cave wanting to find out more about what Noir was up to.

The ultimate battle with the most powerful gaichuu, the Cabernet, wrecking havoc in Yuusari central, comes to a close. Lag stands up, together with the Heart of all of the friends who he's received and become entangled with.
