Nero

Nero is an militia-like organisation made up of only Media.

It is not clear to the public what goal they want to achieve. But they are recruting Media all over the world.

Each of their members has a tattoo somewhere on their body.

Their leader is an Anima called Valeria.

Beryll is an assassin of Nero.

Rai was part of Nero as well, but he left at a young age.
