A Sirens Word Gives Life {BNHA} (OC x ?)

A siren has the power to control everyone and everything. Kijo Morri has the quirk named Siren. Mainly, she just acts like she has a water quirk because it's a very rare quirk and people want it for themselves in whatever way they can get it. She can also transform into any water creature she wants to so she can better handle water. When she gets into U.A, how does everyone react to her?
