Mattias is one of the many Schneien children. He is part of the set of octuplets including Tobias. He has narcolepsy, which has a constant impact on him. He always appears sleepy, and will often pass out at inopportune moments. Despite his own troubles, he looks out for Tobi, and supports him as much as he can. Sweet and even-tempered, Mattias is gentle boy who looks after others. He and Tobias seem to be closer to each other than some of their other siblings. Mattias cares about Tobias's physical and mental well-being, and goes out of his way to try and help his brother when he can, even when Tobi literally pushes him away. He is prone to daydreaming, in part due to his narcolepsy. He is also German (No accent needed!)
