Main article: Social Link/Yuko Nishiwaki
Yuko Nishiwaki is the team manager of whichever athletic club the protagonist chooses to join in Persona 3. Completing this Social Link will unlock the Persona Siegfried.
After the protagonist greets her a few times after club meetings, she'll go out to eat with him. Yuko expresses concerns that she eats too much, but attributes it to being so active. Another girl bullies Yuko because a basketball player dated both of them at the same time, without their knowledge. The protagonist can choose to become romantically involved with Yuko, and through their relationship, he helps Yuko learn about what she wants to do in the future after they help coach a group of kids.
If the player chooses to play as the female protagonist, the Strength arcana Social Link is replaced by Koromaru. Yuko then appears as a minor character in different events throughout the year. It is also revealed that she is friends with Rio Iwasaki, as she appears during some of the Chariot Arcana Social Link events and plays a part during the sports retreat at Inaba in early August. She also reveals romantic feelings towards Kazushi Miyamoto, whom she manages, even going as far as saying that she would marry him if she cannot find anyone else.
Yuko has short light black hair tied into a short ponytail, and wears a red clip on her left side. She has brown eyes. Her skin is a light brown complexion, implying that she may be mixed-race or simply tanned from frequently being outside for her job as team manager of the track team.
