Crimson demons were experiments. They got their magic stats and/or skills maxed out, the Barcodes they all have are the result of some kind of genetic manipulation that causes every newborn crimson demon to have one, so they could be identified by the ones experimenting on them. However, it seems those who experimented on and with them, got rekt, and don't exist anymore.
