Gariben-kun (ガリベンくん?)
Seiyū: Mayumi Tanaka

A rival to Hidetoshi Dekisugi. He appears to be a soft-spoken and decent boy, however deep down inside he resents Deskisugi of being better at anything than him. In one chapter, he makes cruel prank calls to his rival, telling Dekisugi to go to hell every night. This problem caused Hidetoshi's grades to drop, and Doraemon decided to use a specific gadget to teach Gariben a lesson. Gariben begged Hidetoshi not to tell the teacher or the rest of the class about it, and the latter forgave him, on the condition that he promise not to do it again.
