Description
Ken Ryuushou serves as a main character and close companion to protagonist Ryusei Amanogawa. At 10 years old, he actively engages in borg battles alongside Ryusei and Katsuji Matsuoka, piloting his designated machine Electrical Speedwagon—later upgraded to Electrical Speedwagon V.

His family operates the Chinese restaurant Shōryūken, establishing his background; his younger sister Linlin Ryūshō occasionally appears there, anchoring episodic storylines centered on the establishment. Ken exhibits a notably gluttonous personality, with multiple descriptions emphasizing his profound love for food.

Demonstrating determination beyond borg combat, Ken joins Ryusei and Katsuji in pursuing bodybuilding during episode 23 ("Sweet Muscular Pain"), where they train rigorously at a gym. Throughout the series, he consistently supports Ryusei during confrontations against adversaries including secret organizations and formidable opponents.
