Like what the title is I can't remember an anime. The settings goes with a school like story and there's 3 kind of division. Each division (like 3 cities in japan) have 2 representative. The characters are like Siblings with blonde who uses her voice as powers, he xender r brother uses his fist with some dark attributes. Another siblings uses guns 1 is sniper the bog bro and the sis using dual guns. I can't remember but they have chips like cpu chips but rather small on their napes.
Thank you for the replies will be waiting to find that anime again. I'm not sure when was it aired but maybe around 2015 ish if not 2014 something.omegle
