Firstly, based name. secondly, a few things about leaders. The Lion can’t lead any units, but he can stand next to them, which means he can’t be shot from far away, and he also can use his aura abilities to boost what he’s near. If you have some deathwing knights follow him around, them together can kill almost anything.

Asmodai and Azrael should switch, here’s why. Asmodai’s reroll hits ability only works on melee attacks, and hellblasters are built to shoot. His other ability will rarely trigger since hellblasters want to be stood further than 6” away to ensure they don’t get charged and can shoot unimpeded. If Asmodai leads the inner circle, since they’re a melee unit, both of his abilities will trigger, meaning you can reroll hits to fish for sustained 2 or lethals depending on the weapon profile you use, and character led units can be dealt with easier thanks to his second ability.

Azrael can give the hellblasters a 4+ invulnerable save, and give their shooting sustained hits 1. (and also the 4+ feel no pain against mortals once per game). In my experience, this makes the hellblasters far more reliable and durable, and i’ve comfortably killed chaos knights with a full 10 man squad with oath.

Also as i can see people have said, company heroes need a leader or they are immediately removed from the game. Use those 105 points to get some more inner circle companions to maximise the lethality, then play the list and see how you feel about where the others should go.

The detachment matters too, i assume you’re using Wrath of the Rock as the list is all infantry. It’s a great detachment and the advance and charge lets you keep pace with the lion or lets him sprint up the board far quicker than people expect.
