Both Fractale and Kaiba have the concept of "memory data", which means that both shows feature alternate bodies with the possibility of loading an entire individual onto them.
They also feature a world that has changed and modernised, but not entirely into the best. Not a dystopia in every sense, but a world that has developed into something very unfriendly.
Both protagonists are also searching for a girl who possibly hold a lot of answers to their past and future.
