**Seo Yoon** (서윤), known as **Aoi Shizuka** (アオイ・シズカ) in the Japanese localization, is an mercenary hired by the Coffin Company TASKFORCE and the commander of ALT Squad. She is a 19 year old that stands at a height of 168.5cm and weights 50.7 kg. According to the Administration Standards, her CRF is a Grade B.

Seo Yoon has no family, and alone ever since she could remember. Her unreliable situation forced her to be more proactive and faster than anyone else in order to survive, yet ended up collapsing from overworking herself too hard. Her "friend" told her something that she remembers to this day: *"Everything happens in due time. Things won't go your way just because you're impatient! You can whip your body all you want, but it'll only lead to more pain, and nothing will change..."* Seo Yoon now wishes to live her life by this advice as a disciplined individual who'll accept the world as it is and can rely on her circle of friends without fear.

*Seo Yoon is an attacker who can enhance her allies' offensive capabilities through outstanding command skills.*
*She is the commander of ALT Squad who has been performing well in the Underground. The Underground collectively refers to private military organizations that illegally carry out TASKFORCE missions. Among them, betrayals and deceit are a daily occurrence. In such a ruthless environment, she had lead her team to complete more than 10 missions within a matter of months without losing a single member.*

*She refused to open up about her past, but her tactical knowledge shows that she received professional training similar to that of a military academy.*

*Seo Yoon has awakened her Altergressive power! A ranger specializing in telekinetic ally controlling firearms and her spear Misteltein, she distinguished herself durin gthe battle with the Replacers, and received an official license to run a squad, which used to operate illegally in the Underground.*
*A lot of Underground Counters are jealous of her success, and it's a mystery among them why such an independent and successful individual would insist on staying with a small TASKFORCE company that doesn't seem to offer much.*

## Personality

Seo Yoon is a charismatic commander of her squad, using her charms and leadership skills to lead the battle. She is also highly intelligent, manipulative and cunning— traits she believed were necessary to survive as a mercenary on the Dark Network. She has deceived people, including her own allies, to reach her objectives. While she would never truly betray her friends and comrades, Yoon doesn't show much remorse for tricking them so as long as her mission runs as planned.

Yoon's relationship with Yoo Mina can be best described as a friendly rivalry, someone who would treat Yoo Mina like a close friend and tease her at the same time, while being a rival when it comes to climbing up the ranks.

She can also be very competitive, and will never back down from a challenge. This is reflected in the Academy Field Day event where Naielle Bluesteel constantly mock and challenges her in various tournaments, which Seo Yoon gladly accepts and beats Naielle in nearly every challenge.
