The official website for Weekly Shounen Sunday announced that the completed manga series Kami Nomi zo Shiru Sekai will receive a spin-off manga series titled Kami Nomi zo Shiru Sekai On The Train which will start publishing on September 19th in Club Sunday.
On the train? I don't quite know what to expect from that title. Is it going to be inbetween scenes of what happened during their travels from home to school? Can't remember ever seeing anyone in a train in the original series.
I guess "on the train" means it is supposed to be read when you're on the go? As in a light and comedic manga with no deep story, neither text heavy. Also, they better include Keima on this one. Other spin-off series (Soul Eater NOT, for example) tends to just include the girls.
