When her dreams and everyday life starts getting interrupted by a triangular dream demon who loves to make deals, things begin to change....

Lillipup's life revolved around a room in the pound. Having lost all hope, he forlornly awaits the day when he finally rests in peace, knowing that no Trainer would want to adopt a useless creature like him. But after being stolen by a strong-willed teenager, Lillipup realizes that he shouldn't have given up so easily. Overjoyed at the prospect of being taken care of, he relishes every single moment he has with his Trainer, promising Arceus that he would protect her at all costs. He would never leave her side. Even if it meant leading him to his death. •••
