Looking for a Historical Manga

Set in around the Taisho era, the protagonist was dismembered at some point so he is currently in the form of several body parts (I remember a hand, and maybe they find an eyeball at some point) in a jar. He made golems(?) with his friend, and one of the golems he made, a young girl, is helping him find all of his organs and limbs. Some past disagreement between the man and his friend lead to his dismemberment.

I don't think it was romance, wasn't school life, and (not sure, but I think) not psychological.

Please any leads would help. I've been looking for a while, but it's so vague in my memory that it's hard to find on sites such as Mangaupdates.
