Taking a stab at the transcription of the characters...
The name on the left, only partially visible in the manga, appears to be 土井 (family name = Doi?, given name = Natsuki? 菜月)
In the anime, the name on the left looks like (工 or 土)井(菜 or 莱, or a fancy 菊 or some character with 糸 or 釆)
The name on the right in the manga and anime looks like 魚塚三郎 (family name = Sakanazuka?, given name Saburō?)
The second of the two characters above the name on the left is 拾.
The rest of the characters I am unable to read. I hope someone can help fill out the missing characters and suggest potential romanizations of the names.
