Ikkaku Umino

was a shinobi from Konohagakure.

Background
When Iruka's mother was injured while protecting him during the Nine-Tails' Attack on Konoha, he offered to look after her. His father said he would look after her since it was the parent's job to protect their child, not the other way around. He instructed Iruka to flee. Iruka did not listen, forcing other Konoha ninja to drag him away from the battle. His parents were killed by the Nine-Tails. Their names had been added to Konoha's Memorial Stone when they died.

Personality
He seemed to be a very stern, but loving man seen from his refusal to let his son stay on the battlefield during the Nine-Tails' attack while readily defending his family and village.

Appearance
Iruka's father had brown hair which he tied back into a ponytail, dark eyes and a thin moustache. He wore the standard attire of the Konoha-nin inclusive of forehead protector and flak jacket under which he wore mesh armour that showed past his sleeves.

Trivia

 * means "Narwhal".
