Nagisa's Father

￼Nagisa's Father is the father of Nagisa Shiota and the (presumably ex) husband of Hiromi Shiota. Despite appearing in both the anime and manga before Hiromi, his name has not been revealed.

Appearance
Mr. Shiota has short light hair that is presumed to be blue, like his son's. However, in the second season of the anime, his hair is dark grey/black and his eyes are black also.

Personality
Mr. Shiota appears to be a calm man who feels guilty for leaving Nagisa. He seems to still care for his son, even taking him out for sushi.

History
Not much is known about Mr. Shiota's past other than he was once married to Hiromi Shiota. At some point, he left his wife when Nagisa was (presumably) still young.

Plot
When Class 3-E returned home after the Assassination Island Arc, each student spent the remainder of their summer vacation in their own way. Mr. Shiota was first seen having sushi with his son and asked how Nagisa was fairing living with his mother since she's so strict. Nagisa tries to ease his father's worries by saying it wasn't so bad if she's not aggravated. Korosensei suddenly appeared behind Mr. Shiota with a sign to ask Nagisa to go to the summer festival. Nagisa then hurriedly said his goodbyes to his father and ran out. Mr. Shiota commented on how his son is doing better and has not been seen since.

Abilities
Mr. Shiota has not displayed any unique abilities.

Nagisa Shiota
Nagisa and his father seem to have a good (maybe a bit distant) relationship. It is shown that Mr. Shiota feels guilty for leaving him. Nagisa, on the other hand, seems to have made his peace with it.

Hiromi Shiota
Mr. Shiota isn't shown interacting with Hiromi. The two were once married and even had a child, Nagisa, together. According to Nagisa, Hiromi drove him away with her harsh temper.

Trivia

 * His first name is unknown.
 * The age Nagisa was at when Mr. Shiota left Hiromi is also unknown.
 * There is a possibility that his surname is not "Shiota", depending on if Hiromi changed hers and Nagisa's surnames to her maiden name or not. However the chance of this is very slim.
