Yool (율) is a C-Rank Regular Scout and is currently with Baam's crew to rescue Ha Jinsung. He is in an unknown team, but one of his confirmed teammates is Kell[1]. He is also acquainted with Levy, and it is implied that he is part of a crew sponsored by the Zahard family. 

Appearance & Personality

He has short white hair and slightly grey eyes. He has a snake coming down from his hair. He has shown himself to be somewhat arrogant and quite confident, taunting Baam multiple times and taking him on in a fight without hesitation. He often squints as he smiles, adopting a sly and cheeky demeanor. 

Tower of God: Part 3 - Deng Deng

He is first shown in episode 1 as he poison Yihwa and Hong Danhwa. He orders Kell to shut Yihwa up when she is not completely poisoned. Then in episode 3, he challenges Baam and he calls Baam out to fight. He loses to Baam after failing to poison him with his snake spell, then admits defeat and mentions he is holding Yeon Yihwa as a hostage. He uses her to negotiate with Baam, putting himself and Kell on his team and traveling with him to rescue Deng Deng in exchange for giving Baam Jinsung's location at a later time.

He later sneaks into the Regular Arena on 52F with Elaine, Louie, Kell and Hockney, killing two attack dogs and making his way to the control tower. There, he lowers the barrier protecting the arena as Baam breaks Deng Deng out of his cell, then prepares an escape ship to carry the party away as he blasts away the arena's wall with the ship's cannon. 

After their escape, Yool is very excited to journey forth to Yama's lair, but is shocked and contemplative when he learns that he cannot enter himself.

Powers and Abilities

Yool, as a scout, generally prefers hand-to-hand combat, getting up close and using a variety of spinning-based martial arts. This style and his spell also demonstrate competence at stealth operations. 

Snake Spell

Yool's ace up his sleeve is a spell that takes the form of two white snakes dangling from his hair accessories. Upon activation, a snake opens its mouth and stretches from Yool's hair, turning red as it bites its victim. When its fangs pierce the skin, the snake spell injects a poison that will paralyze and kill its target [2]. This spell does not seem to work on Baam. 

Engineering Skills

Yool's technical prowess allows him to pilot floating ships and quickly grasp technical infrastructure, demonstrated when he takes control of Yama's Regular Arena's control tower to help Baam escape with Deng Deng. 

Notes and Trivia

  • He is weak against beasts.[3]


  • (To Yeon Yihwa) "Because you are Jue Viole Grace's companions, obviously. I guess you could say, you picked the wrong guy to make friends with."[4]
  • (To Viole) "Take us with you to go save your master. If you do, we will let the hostages go. I know it sounds crazy, but it wouldn't hurt you to let us come with you. We know where they are keeping Jinsung Ha. If you take us with you, we will show you where he is."[5]
  • (To Viole) "We will keep our promise if you bring us with you. I never lie."[3]
