History
Not much is known about his 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. Nagisa's father was first seen having sushi with his son and asked how Nagisa was fairing living with his mother's strict personality. Nagisa tries to ease his father's worries by saying it wasn't so bad if she's not aggravated. Korosensei suddenly appeared behind Nagisa's father with a sign to ask Nagisa to go to the summer festival. Nagisa then hurriedly said his goodbyes to his father and ran out. His father commented on how his son is doing better.

Later, in chapter 112, he is mentioned by his ex-wife, Hiromi Shiota, and Nagisa remembers that he left because he was unable to keep arguing with her.

Nagisa's father makes his next physical appearance in chapter 178. He and Hiromi attend Nagisa's graduation together and reveal they plan on giving their relationship another try. Nagisa's father also reveals that a month prior, Korosensei visited him and explained some things about Nagisa to him. This includes the fact that Nagisa requested to be called by his first name in the event his parents got back together to make the transition to his "old name" easier.

Abilities
He has not displayed any unique abilities.

Nagisa Shiota
Nagisa and his father seem to have a good, but a bit of a distant relationship, shown when he feels guilty for leaving him. Nagisa, on the other hand, seems to have made his peace with it although it is later revealed he hoped his parents would get back together.

Hiromi Shiota
He wasn't originally 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. However, as of chapter 178, the two are giving their relationship another shot.
