Work in progress!
I will divide the titles in different sections according to the prevalence of yuri in each of them:
5/5 Yuri is the driving force of the story
4/5 The yuri is there but it's not the driving force, it involves the main character/s though
3/5 Yuri as a side element to the story, it doesn't involve the main characters
(i.e. a gay couple in a non-yuri work, a side character having a crush on a girl, etc.)
2/5 It's debatable whether this is yuri or not, includes yuri bait (i.e. Hibike Euphonium)
1/5 Yuri *only* as fanservice
Notes: *Prequels or sequels of the main title won't be included, spin-offs are an exception.
*One-shots per se are not included, fully translated anthologies are in this list though.
