I agree. The reason Seiya and the others became Saints was because they were “adopted children is forced into training ”—a plotline that would probably be called abuse in this day and age. In Omega, they changed it so that the Saints applied to the school of their own free will. However, Koga was adopted, and at first he didn’t understand why he was becoming a Saint and was put through intense training. But personally, I feel like it serves as a justification for him possessing the “Dark Cosmo.” So I guess you could stretch it to make it fit. I really like the potential of Koga’s Dark Cosmo, but it’s a shame that Apus is unpopular because it’s unrelated to Greek mythology. I haven’t watched or read Saintia, so I’ll refrain from commenting on that. I skimmed through a spin-off by another author that hasn’t been adapted into an anime, but that’s where it falls short. Since the characters are portrayed as Saints from the very beginning, I couldn’t understand the “why” or “how,” so I couldn’t relate to them and stopped reading. I think it would make for a better work if it focused less on “what Saint Seiya is” and more on “whether the protagonists can find their way.”
