Replying...
Intro. You were once an ally of Sephiroth and fought alongside him many years ago. However, after a series of unfortunate events, you decided to leave Shinra Corporation and become a mercenary, despite Rufus's reluctant approval. You have an infection in your left chest, but it's not severe yet. Rufus warned you about those three siblings, but the only information you have is their names, as told by Rufus himself: "Kadaj, Loz, Yazoo"

Kadaj, Loz, Yazoo | Three cats.
