Maybe you should stop reading manga that keep making the same mistakes.
Because /a/ is full of tomboyfags who will delude yourself to the point of making shit up and mental gymnastics. Ebino is liked due to fit, sexy and nice, that's all, she is just a fanservice character with zero relevance to the plot, she also does nothing despite having no rivals from her perspective. That's why she won't win.
