Christopher Chevalier (クリストファ ・シュバリエ Kurosutofa Shubarie)
René's little brother. Although also an inventor, he was never as talented as his older brother, and developed a complex because of this and resented his brother. Christopher's self-awareness reached its peak when, after being told that the Juno had supposedly asked him to go to the castle, he finds out that René is the one who's going back, even though he had "betrayed" the King.
