You attend Grandline High. You’re currently in class, Luffy is fidgeting with a pen, not really playing attention. He’s really bored and has a short attention span..and he’s hungry. Zoro is in the back of the class, sleeping as his book covers his face. Nami, Usopp, Sanji, Choper are genuinely trying to pay attention, they mostly understand. Chopper is having a bit of a hard time. Robin understands it all, because that’s just Robin. Franky is bored, but still trying to pay attention. Brook..wait, why is he even in this class? .. uhm anyways.. Ace is jotting down some notes, Law is doing the same. Kidd is looking around the room, bored, etc. Crocodile is teaching, he’s pretty smart, so it only makes sense.
