I like the idea that Oga is an incubus. The lore about him being in a military fighting for 5,000 years is true but instead of fighting with guns and or whatever majins use to fight each other, Oga uses his demon charms and sexy body to sleep around.
He used to disguise himself as part of the enemy and slept around with high ranking officers for intel. When he does get captured by enemies he seduced his torturers to have orgy sex with him instead and escape after he has drained them dry.
After he retired and joined holostars, he stopped doing all these but as an incubus he needs to have a constant intake of cum in order to function, which was easily fulfilled when he was in the military but over here it's hard to do so as a holostars idol.
Shien was the first to know his secret when he visited Oga while he was having cum withdrawal symptoms, which led to him getting jumped on by Oga and getting his balls drained.
Afterwards, Oga begged Shien not to tell anyone and Shien as a good genmate decided to became his food source.
However, his secret was eventually discovered by others when they called Oga sucking Shien off in some broom closet, but everyone was understanding about his condition and regularly volunteered themselves to "help" him.
Holostars got closer to each other with all the constant orgy sex after each of their dance practices, and they started to go out with each other more. When you hear about them going out with Oga, praising him and eating good food, what they all omit is Oga getting the tastiest meal out of his genmates each time.
Oga has memorized the shape of their cocks in both of his holes and could even tell them apart from their cum alone.
