Prue

Prue is a mysterious male character who lives inside a green crystal once owned by Cain Dressel. He is called "Big Brother" by Pino, another being similar to him. When Cain pilots Valvrave II, Prue awakens and shows strong hatred toward humans, especially those from the JIOR nation. Prue and Pino share a dark past filled with resentment. Later, a series of events separate Prue from others, and he goes missing along with Valvrave II. He later shows up hidden in a mansion during a secret ritual. Prue eventually meets Pino again inside the Valvrave I engine, where they reunite and witness Haruto Tokishima's final moments together.

Prue is a male with blue hair. When he is inside the green crystal, his physical features are not fully shown, but his presence can be strongly felt.

Prue holds strong negative feelings towards humans, especially those from JIOR. He shows deep anger, and his attitude is cold and distant. He is closer to Pino and acts like an older brother to her.

Prue is a young Magius, the same kind of being as Pino. Both have lived for a long time and hold many secrets. Prue was kept safe inside a rare stone by Cain Dressel, as Cain feared his special ability would fade.

Prue can control hard energy to form limbs from the lost parts of Valvrave II and activate the giant machine. He also has a unique ability called "Jack," which lets him move into others' bodies, although his power got weak over time.
