Ken Ryuguji is a founding member and the vice-president of the Tokyo Manji Gang in the anime series, Tokyo Revengers. Ken’s authority over the Toman gang is more or less equal to the leader, Manjiro Sano. Ken is able to freely command the members and increase their morale. Ken’s fighting ability is also nothing to laugh about, he once was hit in the head with a metal pole, but still stood firm and defeated 20 opponents in a battle.
