A new Aldnoah.Zero visual has been put up on Shinjuku and it gave some of the fans a sense of relief. The reason behind it is that the visual shows Inaho on what seems like an event after the last episode of the first season.
Let's not forget that the writer of Aldnoah.Zero is Gen Urobuchi. A guy we all know because of his plot twists. You never know if Inaho really is alive.
