Up to the name

In the city of Tokyo, Itazuka Kakare was bullied often at school for his nerd-like appearance, and nothing was really going his way when he found out a secret he was never meant to know. One day, he looked at one of the family pictures, wondering who the others in the frame were. They all looked in their tens, atleast five years older than Kakare. An address was written on the back of it. An alleyway. Kakare followed it anyway. (This reminds me of the seven deadly sins but different) In the family, Assassins are given names. Aishizu Kakare - Sorrow, water, Male (second oldest) Fubuki Kakare - Snow, cold, female ( Middle, user of the ice bow) Raiden Kakare - Lightning, spark, male ( Eighth generation clan leader) Anichan Kakare - Lust, love, female ( second youngest of the Kakare clan ) Hana Kakare - Narcissm, self-lust, female ( Clan leader's sister ) Yami Kakare - Hatred, Fire, male (Seventh generation holder of the fire ring) Bokeru Kakare- quite literally air headed! Male (Nobody knows his rank) Reiko Kakare - Hot headed, Bloodthirsty, female (Fifth rank assasin) And then.. Itazuka, which trains to get his powers
