A boy with dark messy hair and round glasses. He is a student at Ludwidge Academy and serves Elliot. He has a calm and collected demeanor and is hardly rattled by anything. Leo is very observant and discovered Oz's identity as an intruder. Despite being Elliot's servant, he doesn't always take his side and will make him apologize if needs be. He is seen with Elliot at Sablier. Leo carries a gun and is apparently hopeless with it and swords, according to Elliot.
Leo was born into a dark life, attracting misfortune to himself because he had inherited the soul of Glen Baskerville as part of The Rule of 100 Cycles. Despite inheriting Glen's soul, Leo was capable of blocking out the influence of the other Glens who reside within his soul because of an effect brought on by the Sealing Stones.
After being traumatized by Elliot's death, he formed an Illegal Contract with Jabberwock as a part of his Succession Ceremony of Glen Baskerville. However, Leo discovered that the emotional trauma brought on by the role he was meant to play was too much for him to handle, allowing a past Glen, Oswald, to take over as the reigning Glen Baskerville. Even so, Leo continues to observe Oswald's actions as Glen from within his soul, alongside the other past Glens, even sharing information and memories with Oswald on occasion.
