well... i dont have a favorite big brother but the sisters will have to be Ricu and Triela.
Ricu
Why: well... i use to be that shy when i was little just like her and also... i'm going to be a sniper when i go to the Mil. ever since i was little, sniper rifles and scoped guns has always been my choice.
Like: i like ricu for way of life, she dont want to do what she does but if she has t oshe has to. ricu also looks for the bast was to carry out her mission.
Triela
Why: Triela is the most normal, she's not strict or anything but the pistol in her pocket has to say other wise.
Like: triela has a kind heart and when you piss her off, that kind heart flps a 180 and'll kick your ass withour question.
