Ogma was a middle-aged red deer, with magnificent curling antlers. He wore standard square-framed glasses with a dark green suit under a pale brown, collared shirt with a black tie and brown boots.
His enigmatic personality was shown multiple times as he often bought Louis expensive items depending on whether he was disappointed or proud.
- Taser prod: Ogma had a taser to ward off intruders in his residence. When he had heard a scream from his son, he went to his room with the taser, but Louis was actually fine and had just felt a pain from his right leg.
- He bought Louis from the Black Market for ¥7,000,000 (seven-million yen) with the intention of making him the successor to the Horns Conglomerate.
- "Oguma" (小熊 in kanji) means a small bear. It can also refer to Oguma (小隈 in kanji), an area in the city of Asakura, in the prefecture of Fukushima.
- Ogma is named after the Gaelic god of speech, language, eloquence and learning.
- During Louis' childhood, Ogma bought an expensive 500,000-yen bicycle for failing to achieve a perfect score on a test.
- He's privately known to be sterile, and is unable to have children of his own, leading him to adopt Louis in the first place.
