Azz isn't as optimal for a ship with Iruma because Azz is no way in it for himself when it comes with his relationship with Iruma.
"O passionate gentleman, You'd always praise me, but never find fault."
Clara"knows of both passion and pleasure, but (S)he isn't ready for love yet. Sorry, too inexperienced."
Gyari is the selfish prince(ss) in this situation, "whose desire for love is only satisfied by [Kuromu or perhaps Irumi later?]: Am I satisfied with that? One sided affection is too dull."
Ameri's love for Iruma is truly love that burns like fire. And with Iruma's flustered face Iruma's love for Amelie too burns like fire. That's why I ship Iruma x Ameri because they truly have burning passion for each other.
