"Have you been a good boy, Rainhart? Until we find Lilia, please go play with Rion."

Rainhart
Rainhart is 15 years old and is the second Galerian Rion encounters. Like Rita, his story is also extremely sad. At 3:00pm, he is given medicine. In reality, Rainhart is a kind, gentle boy, but the medicine awakes the monster within him. Rainhart claims the monster will eventually consume the real him. Dr Rem often gives Rainhart his medicine at 2:50pm, not 3:00pm like is is supposed to and as a result, Rainhart has become obsessed with the time, constantly setting clocks to 2:50pm.
He is the one who killed Rion's parents Dr Steiner and Elsa, setting Steiners wristwatch to 2:50pm and placing a pocket watch set to 2:50pm in Elsa's mouth, post mortum. His attacks depend a lot upon illusion, and when Rion breaks the allusion and burns Rainhart alive, Rainhart shows Rion what lies in his subconscious.
The real Rainhart begs Rion to keep the fact he failed a secret from Mother. If she were to find out, she'd force more terribly painful medicines on him. He explains that it wasn't him that killed Rion's parents, but the monster that awakens within him when Rem administers the medicine. He begs Rion o believe ha he wasn' he one who did those things. Rainhart's death actually made me cry a little, it was just that sad.
