Team Tangsooyook was the team formed by Jyu Viole Grace and the 7 Regulars whom he was tricked to accept (by Ja Wangnan) at the end of the Trustworthy Room Test on the 20th Floor. Viole was at first unwilling to have anyone climb the Tower with him, but he eventually bonded with his teammates. The team continued to stay together after two years, from the 20th Floor through to the 29th Floor until the Hand of Arlen incident which resulted in Viole and Horyang leaving the team; due to some circumstances Koon had to take Team Tangsooyook to win the Workshop Battle. The team was reunited after winning the Workshop Battle. Following the events of the Workshop Battle, Horyang is currently in coma after Cassano stole his 'Devil' part, with the team's objective being to capture Cassano who was riding the Hell Express. They somewhat succeeded in their objective.
Due to the capture of its last remaining members, this team has been disbanded.. But following the events that took place on the Last Station, this team might be active again.
One interesting aspect of this team is that several members either wish to change the status quo of the Tower (Viole, Wangnan, Horyang and Akraptor) or clean up the corruption of the 10 Great Families (Yihwa).
Tan-soo-yook is described in The Company's translation of Season 2, Chapter 1 as thus: This is a fried pork (usually pork, can be some other type of meat) covered with the usual flour + egg coating. Then it's overlayed with sweet and sour sauce that's also got some veggies like apple, onions, and bell pepper (usually). These can often be ordered in party size.
English-speaking TOG fans sometimes refer to this team as "Team Pork".
