In Persona 3 Portable, Koromaru replaces Yuko as the Strength Social Link for the female protagonist. Koromaru's Social Link takes place at night when the female protagonist takes him for a walk. Typically, he wants to be taken for a walk on Monday, Wednesday, Thursday, Saturday, and also on days off school. If he is ready to rank up, then the rank up event will occur. If he is not ready to rank up, he has no hangout events like other characters do. Instead, the female protagonist gains 10 points with Koromaru whenever she walks him. Occasionally, the two will come across other Social Link characters and the female protagonist will also get Social Link points for those characters.
