In the wake of Shoujo Beat's end as a magazine, Viz soft-launched today their newest venture, Viz Signature IKKI. The IKKI part comes from Monthly IKKI, Shogakukan's monthly seinen, or young men's, magazine where all the online mag's titles will come from. New chapters will be released every week online via http://sigikki.com and, if a title is popular enough, it will be released in graphic novels via the Viz Signature imprint, hence the full name.
The first, and only, title out right now is Children of the Sea, in which you can read the first chapter here and an interview with its creator, Daiuske Igarashi, here. More titles and the full slate will be announced at San Diego Comic-Con before IKKI's full launch in August, with mentions to Natsume Ono
