2) Yoshio Akira - Koi no Manimani
3) Shoko Nahara - S to M no Iibun
4) Uzui - Playboy na Ore ga Onna ni Saremashita!!
5) Sunae Hata - Orikou Yaju Niwa Aragaenai
6) Fuuki Mame - Bukiyou na Kimi to Senaka no Jijo

9) Nobana Saori - Osananajimi ga Do M de Tsundere Nan Desu ga
10) Seto Umiko - Double Koukou Debut
11) Sakura Riko - Gogatsu no Hana wa Made Sakanai

Those names aren't entirely accurate lol google translated maybe? xD

Omg wow amazing how did you have all of them

Eh? They're not? How do you say so (゜ロ゜)

I said POSSIBLE names for that reason.

I did use Google translate and the problem with that is some things can be read in different ways. Google can't always tell but gives its best guess, often with alternatives. Since some of them are the wrong reading someone who knows the correct names should notice.
Though if I went and actually googled them (Not just translated) I probably would have found most of them.

I just know that translating images can be hard since you can't copy and paste plus most people don't have a Japanese keyboard to try and write it out. I was just giving a starting point cause my head was hurting to much to really look anything up.

1) I also used google translate to check the image search. It usually shows the written kanji underneath the 'translation'.
2) Search those kanji words on google. Most of the time it has a manga updates page followed by a directory of their past works.
3) Associate the proper artwork found in the page you provided.

Bonus: some of the artworks found in that page aren't the title artwork. Fortunately some of the works found on that page have been translated (ex. Double Section and Gogatsu no Hana wa Made Sakanai). Also, checking google images is fairly useful since most of the time they'd show you a link to where you can buy a physical or digital copy of the work (ex. S to M no Iibun). That's all.

"Kuzukawa Tachi" was read as "Kuzukawa and others" in google translate. It read it as a phrase rather than a name. The same can be said for "Uzui" which was translated as whirlpool. Kanji can be read differently depending on how you use it.

Eh I'm too lazy to actually do it hahaha so you guys are lifesavers ε=ε=(ノ≧∇≦)ノ
