Weekly Young Jump will publish manga works by AKB48 members Watanabe Mayu, Kashiwagi Yuki, Kitahara Rie and Sashihara Rino. They will start in issue No. 38, with Kashiwagi on the cover.
Each of the 4 members' manga will be released once a month, and each members' manga will be released every different week. So each week, you will see a manga by one of the four members. The pattern repeats every month.
The official site for the collaboration is here.
The titles of the mangas are as listed:
Watanabe: "Mayuyu no Mangaka Debut Keikaku" (Mayuyu's Mangaka Debut Plan)
Kashiwagi: "Yukirin no THE Idol Quest!" (Yukirin's THE Idol Quest)
Kitahara: "Kitarie no Bousou Bungaku Shoujo-do" (Kitarie's Delusional Literary Girl)
Sashihara:"Sasshii Bishoujo-ka Keikaku"(Sasshii Beautiful Girl Change Plan)
I haven't actually read any of these, but based on the titles i'd say Kitarie's and Sasshi's titles sound the most interesting. Whether they're good at mangaka or not, I can't say, but from general fan knowledge, Sasshi is an otaku, so it should be really interesting.
I also know that Rie reads manga like One Piece and Kimi ni Todoke, while Mayu is also into such things. However, I'm not too familiar with Yukirin (she's the only one from these four girls that aren't in my top 10).
And there's more than just mangaka for Kitarie!
If you've not heard, my oshimen Rie-chan is also going to have her seiyuu(voice actress) debut!
She will have her seiyuu debut in upcoming remake anime Gakkou no Kowai Uwasa: Hanako-san ga Kita. She plays Howahowa, the main character's furry friend. The anime will premiere on the 13th of August, on the channel BS12 TwellV.
