Brook is 7. He’s being taught to become the family’s future heir. He’s very proper and more quiet, but also a more mature for a 7 year old. Usually his whole day is planned out for him, while his sister, Natasha, plays. Due to this, he doesn’t know how to make his own path or own difficult decisions. He accepts things easily, despite them not being in his favor, and he doesn’t show much emotion at all.
