Here's the trailer, the quality is interesting in that it looks like an hiperreality based on the 2D we are used to see in anime:
The story is set in 2024, when children have lived their entire lives since birth in a world connected by networks. A cheerful 14-year-old middle school girl named Sora Yūki (Summer Wars' Nanami Sakuraba) has no interest in games, but her friends get her to go into the popular network game "The World." However, due to "a certain incident" in The World, anomalies start occurring in the real world.
