Similar to the love and care Sanemi has for his brother Genya, Killua has for his sister Alluka. Trained fighters from a very young age, both are extremely aggressive and often brash when it comes to making choices in the face of battle, and would jump at the first opening they see.
7) Ban (The Seven Deadly Sins)
