Also known as: カイバ
A 12-episode anime whose setting is an universe where the memories can be somewhat easily extracted, manipulated, stored in memory chips and have a physical form. One can also physically enter someone's memories by means of a "memory gun".
This paradigm leads to body trafficking, body exchanging and a general sense of dystopia due to extreme inequality in the distribution of both wealth and power.
It's opening phrase is "Are our memories, our soul?".
