Ken Ryuguji, or Draken, is the vice-president and one of the founding members of the Tokyo Manji Gang. Draken is a muscular teenager who is exceptionally tall for his age. His head is shaven on the sides and back to expose his signature dragon tattoo on his left temple. His blonde hair is long on the top of his head and kept in a neat braid. He leaves a few strands of hair lose in the front. He is confirmed to be quite lean and has chiseled abdominal muscles. Takemichi remarked that his body does not seem like that of a teenager. Draken has a scar on the left side of his abdomen after being stabbed. He wears the standard Toman Toppoku while with the gang, and his favorite casual outfit seems to be a patterned long jacket. Like the president, vice-president Draken is also quite the wild individual. He loves a good fight and relishes meeting strong opponents. He is rude to those he considers beneath him and makes it clear he does not like them. Unlike Mikey, Draken is the more mature and logical of the two. When the two are being scolded in the hospital by the father of a girl who was assaulted by Moebius, Draken is the one who forces Mikey down to apologize, understanding the man's rage and that it was better to receive his anger without a word than to try and defend themselves. When Pah-chin decides to take the fall and responsibility for Toman by deliberately getting arrested, Mikey tries to get Pah-chin to run. However, Draken stops him, saying that it is the right thing for Pah-chin to do. There are times when Draken's anger gets the best of him, though, and he lashes out in rage. Draken is also a very caring individual. He hates overtly showing affection to the ones he cares about but will go to great lengths to take care of Mikey. He puts up with Mikey's antics and values him as a close friend, carries Mikey around when he falls asleep, takes him to eat his favorite foods, and wakes him up every morning for school. In addition, he gave Emma a plushie for her birthday, and Emma notes that it was one that she had been wanting for a while.
