This is the correct answer. Kiara has consistently worked the hardest for the success of EN, despite Cover's reluctance to throw a bone their way when it comes to events. Despite Gura's mech and sub sales alone probably funding the entire EN branch, they seem reluctant to give the girls any sort of group anniversary event while turning around and doing it for JP girls. Would it be harder logistically? Yeah, of course, but Myth is more than successful enough to warrant it. Cover is lucky half of Myth hasn't graduated after the shitshow that was 2022, tbh. The more we learn about the 2020-2022 days of EN, the more it is obvious that it only succeeded thanks to the talents and their direct managers and in spite of upper management.
