Nino: Approach the person near the boxes.
Nino: Set the library on fire.
You make an attempt, but unfortunately your ability is healing, not fire, so you just heal the shit out of the library's wall. Hell yeah, that did absolutely nothing!!! What an amazing ability!!!
The person with the flowers asks what the heck you're doing.
Nino: Take a flower for Aria.
Nino: You'd better go find Kotor—holy heck there's a cat over there go pet it right NOW
Nino: Take a swim in that pool next to the purple-haired girl.
Nino: Drop some money on the wishing well and wish for a winged to bring you more money. Also, make a wish that your disguise stays unbroken.
