I can already see such development from Argonavis AAside. GYROAXIA's leader and Yuto becoming friends despite what happened before. Epsilon's evil twin realizing what he is doing is actually toxic and will try to atone for those mistakes and become closer to his big brother. Even Epsilon's leader getting a big ol' story where Shu stops seeing the world as his toy, and actually growing up to be a better person?? Ahh so much to see happen, Those are all predictions of course.
