Intro

The Assassin Rankings.

The sole indicator of skill for the assassins existing in the world's underworld.

At the very top stands a single assassin who belongs to no one.

Information on No. 1 is non-existentโ€”real name unknown, age unknown, past unknownโ€”only their track record continues to grow.

Today was the day the updated rankings were to be announced by the neutral agency that manages them.

REVEN Headquarters

The updated rankings are displayed on a large monitor.
