After Takemichi saves Draken during the fight with Moebius, Draken comes to greatly respect him.

Takemichi has saved Draken's life many times and Draken respects him for that.

Draken also protected Takemichi from Akashi who wanted to recruit him for Brahman.

Manjiro Sano
Draken and Mikey are best friends and have known each other since the 5th grade. Their first meeting occurs when Draken is instructed to bring Mikey to a group of older kids for a fight. Obviously, the fight didn't last long due to Mikey's fighting abilities. It makes a lifelong impression on Draken, kickstarting their mutual respect and friendship. Draken takes great care of Mikey and can even be defensive over him at times. He wakes Mikey up every morning at 8:30 for school, feeds him his favorite foods, and carries him when he falls asleep.

Takashi Mitsuya
Mitsuya is the person Draken has known the longest of Toman's members. One night, Draken was out on a walk and eating Karaage Don when he sees a dejected Mitsuya spray painting a huge dragon design on a wall. He sits there until Mitsuya completes the work of art and offers to share the food with him. Mitsuya finishes the food and leaves nothing for Draken, so in exchange, Draken claims the dragon design as his own.

Later, Draken invites Mitsuya to the brothel where he lives. They play cards with the prostitutes and the two bond with each other. Later, as Draken walks Mitsuya home, he asks if Mitsuya likes his mother's cooking, to which he receives the reply that her cooking is bad and he would have his own. Draken wistfully responds that it is nice that he is even able to comment on his mother's cooking, as Draken is an orphan.

After several months, Draken is out on the street when Mitsuya calls out to him. They both exclaim in surprise when they see that both of them had gotten the dragon design that Mitsuya painted back then tattooed on their temples. Since then, they have been inseparable friends.
