Tsuko Family

The Tsuko Clan is a clan in Amegakure, which consistently produces shinobi with a strong affinity towards the Yin Release chakra nature, allowing them to cast strong genjutsu from a young age. As a chakra nature which governs the imagination, use of this chakra nature over the generations has led to imbedding of intelligence within the genes of the clan. This trait however, is less prominent than with other clans which use the Yin Release chakra nature. They are fairly unique among clans which specialise in genjutsu, as they also use a strong ninjutsu, Yggdrasil.
