So close...

Nice.

Oops...

My sister is turning 17 (again, this time hopefuly for real) soon and I'm still looking for yuri manga or anime that she might enjoy. Preferably in german, but english is also okay.

Her taste is mostly sports anime (especially of the fujobait variety) and whatever is currently mainstream-popular in the anime season (think MHA). There's Birdie Wing and Harakuna Receive, but the former afaik was a let down and the latter is, eh, fanservice-y.

Any ideas would be greatly appreciated.

Pocha Climb! should be good. (Although last three chapters need to be found elsewhere.)

On the anime side, apart from what you've already mentioned, which I personally think are both fine, even if not making the yuri quite explicit, let's see what I can find on my list with a good enough score...
Kidou Senshi Gundam: Suisei no Majo
Black Fox
Princess Principal
Shuumatsu no Izetta
Manaria Friends
Yuuki Yuuna wa Yuusha de Aru
Mouretsu Pirates (nothing explicit on the main characters, IIRC, but it does have a real lesbian side couple)

As a Canadian, I quite appreciate that their Quidditch is Lacrosse-based.

Not that there's anything wrong with that, but it's a bit surprising you'd pick it over the original Quidditch that (apart from the later added Seeker position) pretty much mirrors ice hockey. :P

Nice!

Interesting choice...

Nice.

I have no idea why this pairing has suddenly become so popular, but it's fun nonetheless.

Good.

Cute.

Nice.

Nice. :D

Cute.

Lovely. ^_^

The plan may (or may not?) be the same, but her motive is shifting...

Welcome to Jurassic Zombie Park!

She's truly flat now...

Did not see that ending coming. :D

Dammit, house, you knew damn well you were supposed to cosplay an airplane, not a rocket... :P

I mean, this very page has already demonstrated that people don't even remember what happened 4 chapters ago...

Automne very much is the best individual FLOWERS VN in my opinion and it is not even close. So good taste on this random person.

I take this comment as a sign it will get better then. Still haven't managed to get much farther than the very start into it after everything so far just seemed so wrong after the first two parts...

Good.

Nice. ^_^

Interesting.

Horribly spoilery fact (don't say I didn't warn you): Both images for this series here so far are technically of the same pairing.
