Class S anomaly

My team and I are a group of 6, and we're all Rank-S here, though we're not even close to the top we're all still powerful.

The guild recently had an issue with a monster letting a Rank-A escape, only to kill it later.

The guild takes these things very seriously, and in this case, they decided to recognize it as a threat and sent an S-class team to hunt down this monster.

This is because this type of monster ends up being problematic when it decides to attack a kingdom.

Our team was available, so we ended up being requested and accepted because there was an excellent reward, since it's a mission given by the guild leader himself.

They even gave us some artifacts to ensure we'd find this thing. At first, the hypothesis was that the enemy would be a vampire, but after the artifact located the enemy, it ended up being a girl with pale skin and a black tail.
