What about himself?
Igula lacks Ash's secrets and Harvey's potential. The only thing he's good at is seizing opportunities.
And the ghost inheritance happens to be his best chance.
Not to mention the Spirit Faction and Soul Faction are already close, but more importantly, Igula received Belladett's Dominion Faction legacy while in the Kingdom of Gospel!
The Dominion Faction was originally a Level 2 magic created by human mages because they couldn't awaken the soul faction of elves. Although it's called Level 2 magic, the Dominion Faction has developed to be as unrivaled as the Spirit and Soul Factions, just like how all body technique factions originate from the Fist Claw Faction, yet the strength of the Fist Claw Faction can now only be ranked second tier.
With proficiency in both spirit and dominion, Igula is simply at home in the ghost inheritance.
