"An evil, man-eating monster of French legend. Males are called ogres, while females are called ogresses. Twice the size of humans, they possess tremendous strength and can also use magic. Although they can change their shape, their intelligence is low. They will eat any human, but prefer pretty young women and babies. The name "ogre" was invented by writers to give a distinct name to the man-eating monsters. It may also be derived from the name of the Roman death god, Orcus, or from Ygg, another name for the Norse god, Odin."

Devil Survivor 2
"An evil monster that lives in the hills. They are strong but stupid. It is large in size and is said to attack and eat humans, especially young, beautiful women. It can also transform, but its relative stupidity has caused it to often fall for human tricks."
—Devil Survivor 2 compendium
Ogre is the first demon that is summoned via Io's phone. After the subway crash, Io's Demon Summoning Program triggers, and Ogre is summoned to help defend her from the hostile Kobolds in the area. Ogre appears later that day in the fight against Dubhe to shield Io and Hibiki from Dubhe's attacks. It also appears on Tuesday, being ordered to apprehend the culprit behind the JP's hacking incident. However, Ogre is unsuccessful in doing so, as it was destroyed quickly by Botis before doing anything.
From then on, Ogre has made very minor appearances as a weak common demon, the last being in a one-sided massacre from Airi Ban'sCait Sith. It is also still currently present in Io's demon roster alongside Lugh, seemingly untouched in the ordeal against said demon.
