Long time lurker here.
This morning I found a manga to add to our list of ENF manga. It's called Seitokai Osayagami Sayuri wa Ganbatte Iru! and it's from the same artist as Seishokuki.
While Seishokuki is very /h/ in addition to being ENF, Seitokai stays pretty much /e/ for the whole of the first volume (and there is only one volume, which is raw). Since the only site that hosted it had a script that prevented right-clicking, I had to wade through the HTML to get each page. Hope you guys enjoy.
