Nikolai, or more commonly known as little Taras, is the youngest sibling of the Braginski family, and was adopted at a very young age.
Shy, uncommunicative and obsessive, he is a difficult child to work with, often lashing out at other children for very little reason.
He behaves more maturely than the others, but he can be sullen, and refuses to join in games or storytelling unless if the heroine is called Anya - he is somewhat shy when not around his older sister, clutching at her skirts every morning then running to her as soon as she arrives to pick him up.
