After completing Kenta's Advice, my pet Candle can follow very close to me then, Kenta's quest can be repeated many times and apply on each pet without getting the documents again ... my pet kargo started following closely eventhough all I did was accept the quest I'm confused. I read that I should complete the quest again for each new pet, but all I did was just talk to him and the effect applies. Is this a bug or intended?
Not a bug actually You only need to complete this quest once, and your pet (or pets, if multi-pet) are able to move fast If you try to complete quest for another character's pet by transferring, it won't work I believe this is an intended behavior
