Queen of the monsters

UA meets Razor

Just in case anyone is wondering who I am talking about in 1B

The students of Class 1A and 1B (Shinso replaced Izuku) both got off the bus to see a cliff over viewing a forest. They were then treated by Mandalay and Pixiebob, two members of the rescue team the Pussy Cats. There were mostly going over the rules  on what they were supposed to do here but them they mentioned the banning of a specific section of forest

Mandalay: I assume you all see those cliffs over there, none of you are to go anywhere near there

See points the north east as they all see a large cliff side that overlooked a large body of water. It wasn't really anything special so why would they specifically say that it's off limits

Aizawa: it's never been off limits before Mandalay so why is it now?

Mandalay: it's complicated and we shall discuss this later, anyway, Pixiebob do the thing

Pixiebob used her quirk to launch all the students down into the forest below. Whilst the students were trying to recompose, they were attacked by monsters made of pure rock which were identified to be done via Pixiebob's quirk. On the cliff, Aizawa, Vlad King and Mandalay were discussing this "new rule" that was implemented

Vlad: okay the students are gone, so let's discuss this closure of the northeast side of the forest

Mandalay sighs as she knew she was gonna have to explain what she knew about them.

Mandalay: the cliff side in the northeast deferment of forest is home to at minimum three individuals. There are at least two females and one male, we have encountered all but the one they make calls "big sister". The male looks to be around fifth-teen and the girl is around six.

Aizawa and Vlad looked at her like they were crazy. If she knew that there were kids here why didn't they contact the police or the HPSC(Hero Public Safety Commission) about the situation.

Aizawa: and we are learning about this now because...

Pixie: we knew about the boy for about a year now, he specifically asked use not to call the police and especially the any pro heroes. When we confronted him about it, he looked scared and angry. He said that his "big sister" would kill anyone who tried to take him away. The little girl we learned about her being here a week ago

Mandalay: thought that's not the strange part of all of this

Vlad: and that is?

Mandalay: the boy calls the girl his niece

Vlad and Aizawa: niece??

Aizawa: so there are at least three people here

Vlad: the both of you are pro's, why didn't you try to hold capture them then call the police

Mandalay: trust me we tried, the boy's fast and is capable of taking down Pixie's golems in a matter of seconds. He claims that his"big sister" is even stronger than him.

Aizawa sighs as he pinches the bridge of his nose

Aizawa: so what are their names?

Pixiebob: the boy is razor and the small girl is Eri, we have no idea what the last one's name is other than "big sister" or "mama"

Vlad: have you tried talking to the elder sibling

Mandalay: we tried asking Razor about it but he says that she doesn't trust us enough to speak to us. We tried following him but if we get too close to the cliff side he attacks us and tells us to leave before she comes

Pixiebob: we assume this she is the "big sister" Razor mentions

Aizawa sighs, the pussycats were rescue heroes, Pixiebob is the only one with a quirk that can be used in combat so it makes since that they could take down this "Razor" kid
