Toru like Punk.
Tocchan likes Elegant.
Shiba likes Sporty.
Hikaru likes Preppy.
And as you pointed out, Shuu likes Casual. (Your starting clothes are classified as Casual, so you only need to buy a hat and watch to have a full Casual outfit!)
Thank you!
Do you know how to get all CGs and scene replays? I'm still missing a lot...
