Hidetoshi Dekisugi

Hidetoshi Dekisugi , born april 15 2000, is Nobita's classmate and rival for Shizuka's affection. He always gets perfect scores on his tests, but never shows off his abilities. He willingly helps Nobita whenever he has philosophical or scientific questions. His name literally means "brilliant over-achiever", and his last name is a pun on dekisugiru, which means "over achieving". Unfortunately for Nobita, Shizuka tends to prefer the company of Hidetoshi, who is more of her intellectual equal, which leads to Nobita connoting bizarre schemes (helped by Doraemon's gadgets) to keep them apart.
