Zatch Bell! Attack of Mechavulcan

Takamine Kiyomaro is so focused on getting to Coast School that he casually tells Gash he'll build him a new Volcan 300 to play with later, leaving the little demon confused. As the genius races to catch the bus, a massive Volcan 300 suddenly snatches him away. Meanwhile, Gash befriends the very same robot that kidnapped Kiyomaro-later revealed as the "Volcan 300 Generation 4." When Kiyomaro wakes up, he finds himself far from Coast School, face-to-face with a doctor called M2 who insists on making him his partner in the future. But Gash and the other demons intervene, and with Generation 4's help-due to a glitch in its system-they manage to reach Kiyomaro. Though M2 keeps trying to drag him back, the group works together to stop the doctor. However, a new crisis emerges: the time warp M2 used is now spiraling out of control. Gash and the others must act fast to save the city before everyone is pulled into the unstable rift.
