Ikkaku Umino

Ikkaku Umino was a shinobi from Konohagakure and father of Iruka. 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.
