Oh, what the heck, I'm gonna throw in some yuri recs anyway. The first two are completed, the rest are ongoing (as far as I'm aware).
Girl Friends by Morinaga Milk. Probably the pinnacle of the high school girl romance subdivision of yuri. This manga is just FANTASTIC. Memorable characters, excellent artwork, plenty of angst and misunderstandings and UST, and it's just a really cute story overall. The ending felt a little rushed, but it was still pretty good nonetheless. The first collected volume is coming out in English this month - squeee!
Ebisu-san and Hotei-san by Kizuki Akira and Satou Nanki. A story about two office ladies who initially don't get along, but are forced together by certain circumstances. I love the character development, and there's something about the artwork that I love but can't quite put my finger on.
Raubritter by Saida Nika. It seems like kind of a complicated story about two women who run an agency for helping out girls. They take in this younger girl who is looking for her sister, who has mysteriously vanished. It's pretty racy and there are definitely some NSFW parts, but it's very engaging and I can't seem to stop reading it. ^^
All You by Hakamada Mera. A story about a woman Amane who runs into a high school girl at a train station. The high school girl looks exactly like the girl she fell in love with when she was in high school... and it turns out that this girl also fell in love with someone who looks exactly like Amane... it's complicated! The artwork is kinda strange but endearing in a way. I'm hooked so far, anyway.
Sisterism by Yoshitomi Akihito. Haruka and Yoshiko are 14 and best friends. Haruka's sister Sakura and Yoshiko's sister Mai are 12, and they are best friends. Things are complicated by the fact that Haruka is in love with Mai, and Yoshiko is in love with Sakura. Things get even MORE complicated when Haruka and Yoshiko, as well as Sakura and Mai, develop feelings for each other. It's craaaaaaazy! It's also a hilarious and sweet little manga.
One more: Twin Cake by Aoi Hana. Kaede really admires Susuran, an idol, so she becomes an idol herself to get nearer to her. Kaede doesn't really sell, however, and after she flops as an idol she becomes a manager for a talent company. To her great surprise, she is selected as Susuran's new manager! She finds out that it's not quite the dream come true she thought it would be, though...
Whew! Sorry for the long post. Hope you enjoy these manga recommendations.
