Sakagami Tomoyo did quite well over the course of Emerald. She had fallen a bit over Ruby but managed to regain that strength and more. Suzumiya Haruhi also managed to recover most of her strength after a lackluster Ruby period. Eucliwood manages to beat on her opponents even more than expected and this is reflected in a higher stat value. However, Eucliwood exists in the middle of the limbo between Kuroneko and Kanade. She would have to move massively to beat Kanade or lose to Kuroneko and she's already faced both of them anyways. Kyouko, Hirasawa Yui and Hasegawa Kobato also showed improvement across Emerald.

Not much in terms of big falls in Emerald. Makise Kurisu looked a bit weak but she got the job done against Shouko and Ayase. She might have been able to beat Erio as well if she managed to keep up her former level of strength. Hecate also had a fairly weak Emerald. She'll need to fight hard if she wants to avoid finishing the season without any wins.

Taiga may have lost one, but I still think she's the strongest in Stella. Kanade continues to be untouchable. Eucliwood may have improved but she's still nowhere near Kanade.
