Atsushi Ogura

Atsushi Ogura is Yumi Ogura's deceased older brother.

Personality
Atsushi is shown to be a quiet and lonely person. After his graduation from the local school, he stayed at home all day, doing nothing but playing on his computer.

Plot
Atsushi was Yumi Ogura's brother. He was not seen in the anime very often, as he was an otaku and a shut-in.

In "Body Paint", he was crushed to death by a runaway excavator that crashed into his home. He was killed instantly. Yumi arrived home and found her home wrecked; his death, coupled with Aya's, devastated her. Later on, she used it as a justification for attacking Mei, screaming that she'd avenge her brother.

Trivia

 * His home address is 2-8 Akatsukicho Yomiyama City, just like his sister's.
 * His first name, Atsushi, means industrious.
 * He never appeared in the manga nor is mentioned. However, Izumi's brother, Akuma Akazawa appears in the manga, and dies after Shoji Kubodera, so it might be a reference to Atsushi.
 * The causes of his deaths are different per adaption.
