Looks like Shonen Sunday is up and running! The site already has online manga available for reading, as well as other multimedia features, including a trailer for RIN-NE.
There are already a couple of articles online and they have creator bios available for the following:
- Haro Aso, Hyde & Closer
- Kotaro Isaka, creator of MAOH Juvenile Remix
- Megumi Osuga, writer and artist for MAOH Juvenile Remix
- Rumiko Takahashi, RIN-NE
- Yellow Tanabe, Kekkaishi
- Yuu Watase, Arata The Legend
I've read and reviewed the first few chapters of RIN-NE, and found that it eventually grew on me. While in many ways this is a "stake in my Shojo Beat-loving heart," I hope Shonen Sunday sees success.
