Yuko's pops up here and there in Kazushi's social links from time to time as she is the Manager of the Athletic Team. 

Aside from a little bit of drama from another girl who gives her grief, Yuko's storyline revolves around her uncertainty of the future and what she wants to do in life. It isn't until she helps a group of children that she decides she wants to pursue becoming a coach.

Yuko spends a good amount of time being annoyed and confrontational. After a while though, the story shifts focus and you see her sweet side spill out over these children. There's also a moment where she completely embarrasses herself by accidentally making a statement that could be interpreted as wanting to have children with the main protagonist. I mean... Honestly, Persona 3 is perhaps the most problematic in terms that NONE of the girls want to stay friends, but I think this one in particular really has a hard time keeping the romantic implications to a minimum. She falls hard and fast, so expect your lines to be a little on the flustered side.
