Just normal fun person to be around. Has actual chemistry with the MC and is just great tbh. Voice actor in reload really does make the character good though, even though the others arent Pokémon dub level of bad they have a strained anime voice vibe i dont like whereas yuko actually feels like a real person.
Although a lot of characters in persona 3 just feel pretty cool. Stupei hehe
Yuko was always a cool character in 3. Honestly most of the people in p3, I'm talking about literally everyone from the back alley folks to even the lazy businessman, feel like people you could meet IRL.
