I fell in BNHA

Anna

But Tsukauchi had no idea who was on the phone, and so he acted like he did with Kiki's father, and presented himself first.

"Good morning, my name is Naomasa Tsukauchi, I am a detective. We found the children inside a school, and so the police was called since they seemed lost. I am now in charge of them, along with a friend who happens to be one of the professors of this school."

Anna was, at the moment, sitting in the principal's office. After the disappearance of her brother and his friend, she left the school in a hurry to reunite with her family, but seeing nothing could be done, everyone went back to their normal lives the day after. But everyone was alert on any changes, and so when she received a text from Mike, she heard it arrive when usually her phone was on silent mode. Immediately, she left claiming she was going to the bathroom, but went instead towards the principal's office, where she briefly explained the situation and was allowed to stay. The principal had left to inform her teacher, but also the parents.

"Well, good morning, my name is Anna, I am Mike's older sister. I shall be honest with you, I am going to interrogate you to know in who's hands my brother and his friend are."

"Please go on.", authorized Tsukauchi. 

"Well, first of all, the friend professor you mentioned, is it possible to receive more information about him?", Anna asked, professors being the people she respected the most, she wanted to make sure Aizawa was a respectable one.

"His name is Aizawa Shouta, I am afraid right now he is with his class, so it'll be impossible for now to contact. He teaches to teenagers, around the age of you brother and his friend. Hence the first instance confusion wether they belonged to the shool or not. If it is of any reconfort, this is a national school."

Anna let a second pass before attacking, "Well...", Anna always said well before talking," you had no idea wether they were students or not? The security of the school does not seem very trustworthy... Does the students have uniforms? From what I have understood, the professor and the class happened to found Micheal and Killian. Is it such a big school the teachers cannot recognise who belongs in it and who does not? And from what I've heard, you currently seem to be in it, with my kids at that, don't you fear for their safety, considering you are in charge."

Tsukauchi carefully listened, and Mike, who heard exactly what he feared would happen, apologized silently. Tsukauchi nodded to show that it was alright, and as he answered Anna's questions, he wrote something down.

"I assure you the school is secure.", he handed his notebook to Killian so she could read the question," The class found them during a sport lesson, where they weren't wearing their usual uniforms. The confusion came from people invited to the school, who didn't quite knew who they were working with. Lastly, we are indeed inside the school's ground, with the director and in his office, and we were deliberating over what to do when we discovered communication was possible."
