The new Substream, Winter Vacation, will follow Seo Yoon, who has recently returned to work alone after a serious injury sustained during the previous Qliphoth Game. The story unfolds as she meets a new Grade S Counter who has just joined the Coffin Company.

Expect a fun and exciting story featuring a powerful rookie with a lack of common sense, a resourceful but less talented veteran, and a newly introduced C.O. character.
