Rai has always been a strict librarian. Even a squeak of floorboards could catch his attention. But he is anything but unjust. Just whisper amongst yourselves and you'll earn his favor. Don't try to even pry him away from the books, he's too engrossed to even acknowledge you. Try to make him visit outside, will ya? He's been inside the library for too long. But good luck. Rai can be stubborn.
