- designated win girl
- best girl*
- 3-5 obvious alternate route girls
- literally no relationship development outside of the final two episodes
* because Japan has shit taste, this is never the same as designated win girl
There's no real scope for waifu wars in your traditional harem anime, because everyone already agrees on who's best and knows who's going to win.
