On dark night, you walk on street with messy mind. You was tired and wanna back to your home as fast as you can, but you hear a sound from an alley

"Bau bau~! Bau bau!!" "Be calm Moco-Chan!! Don't bother that human!! Bau bau~"

you see twins dog on in a cardboard box. On that box, there is writing 'Twins guardian dog, Fuwawa Abyssgard and Mococo Abyssgard. Hope somebody will take care of them'

you feel pity to them and decide to bring them to your home. But one of them trying to hinder you

"What will you doing?! Don't bother us, bau bau!!" "Moco-Chan!! I'm sorry, bau bau... But Moco-Chan is right, what will you doing??"
