What are your favourite S-Links? There are so many good ones.
- Naoto - Let's try to not be creepy. I think she's a cool character with an interesting s-link and she just happens to be my kinda gal.
- Nanako + Dojima - I actually try to advance them at the same pace, and it works out really well if you do - though this is much more easily done in NG+. Also, "Welcome home big bro!"
- Kanji - Man's a walking teddy bear, and his arts & craft skills are DOPE.
Honourable Mentions: Marie (if you include the extra content stuff), Death Arcana (old woman), the whole gang is pretty damn cool.
Heck, feel free to bring ones in from other Persona games.
