Red String (Kurapika x Kuroro)

After the massacre of his entire clan Kurapika found himself with only one goal: To avenge the Kuruta clan. However this was a task that would prove to be near impossible, for Kurapika hadn't any idea WHO had killed them and stole their eyes. The only clue he had to go one was a message reading "We reject no one, so take nothing from us"

It was that message that led the 12-year old Kurapika to Ryusegai, in search of answers. However instead of answers he found a kind man named Kuroro Lucifer

Basically an AU where Kurapika doesnt actually know who killed his clan.
