There’s no time to worry about Melissa though, as Takuma and the Behemoth set their sights on Tessa and the rest of our heroes. Behemoth pursues the truck through the city, spraying 20mm cannon fire in the vehicle’s wake.

The important PopRot read is that the episode is not disposable even when it leans comedic.
