|Debut:||Chapter 448 cover|
Tsukimi was an old man, with a wrinkled face and long ovular head. He has white eyebrows, and is bald. He has a thick neck, but relatively thin limbs. His eyes are seen to be always closed, as in content and calm.
He wears a light-gray colored robe, with a hood and buttoned collar, and dark colored sandals.
He is very kind, as his automata loved him dearly.
He is very good at building machines, as he was able to build his automata friends.
He created the four wingless automata on Machine Island. He has a passion for moon watching, as his name implies. One day, he saw a giant explosion on the moon, which led him to become shocked and died while choking on his dumpling. His automata put him in his coffin and cried. After his burial, his automata swore revenge on whatever caused the explosion on the moon that resulted in the death of their creator.
