As far as Lucifer knew about the king of Solaris, he had a total of 3 children. Sirius Solaris, whom Lucifer had met before, was the youngest of the 3.
And since the king was no longer strong enough to rule the kingdom, all 3 of his children were trying their best to become the next king.
Each of his children had their own army, and those armies were divided into many different small groups.
To enter that army, people would have to defeat many candidates in front of hundreds of people.
If possible, Lucifer would also want to become a part of that army, but since he couldn't use his Ability in front of many people, it would be very difficult. Or in other words, it was nearly impossible.
Lucifer had always won battles up until now. He had destroyed Hell, killed a lot of bad people as well as defeated many high-level monsters, but that was because he could use his Ability and use tricks.
But in the army, he wouldn't be able to do that.
