From Osamu`s point of view Professors of Beacon are interesting individuals. He sure looks forward for working with them.

Mentioned Professors found their new addition to staff also interesting, sometimes in some disturbing ways…

Almost all Professors were introduced; the last one was Prof. Peach, who is peach-pink hair young woman with shy personality. So it was only natural that she was at lose at the actions of Mr. Dazai after her introduction.

"Such a lovely lady! Would you do me an honor and commit double suicide with me?" the new assistant professor took her hand and asked with such enthusiasm that left all others staring.

Prof. Peach is trying to reply but can say nothing but confused "…Eh?!..."

The Headmaster was fist to come to his senses but did nothing aside from siping his coffee.

Glynda was a close second. And she did what she thought was right – hit the head of the suicide enthusiast.

For the next few days Osamu will be helping Professors with preparations for the beginning of the school year, as good Assistant Professor should. And if while doing so he learned more about them and from them more details about the world he was in – all the better.

For example right now he was going in Vale to shop for some materials for classes, Professors made quite a list. While shopping for them would take some time, but since he was in no hurry he could make some personal purchase also.

Osamu would be glad if local bookstore has manuals for suicide, to compare.

Maybe in the Remnant exist some new for him form of suicide for him to try?

It was late afternoon; Blake was in her favorite bookstore, Tukson's Book Trade, to purchase new eddition of her favorite series and some other books. While she was browsing bookshelf's in store entered another person. Even if from her position she could not see them her sensitive ears caught voices of Tukson and new customer.

"Welcome to Tukson's Book Trade, home to every book under the sun." owner of store greeted new customer in his usual way. He gets a cheerful reply.

"Hello~ could you tell me if you have stuff from this list?"

After some pause.

"Yes, I have it. Would you like to buy it?"

There was some silence, presumably a nod since she heard Tukson walk in the back of the store soon after.

While waiting the stranger start humming some unknown tune and, from the sound of his steps, walking in her direction. Her ears hidden under the bow twitched slight as he stop near her, she did not turn.

"Well, hello young lady! You are so quite I didn't even notice you. What are you looking for?"

Before replying she allowed herself a glance at him. He was young man, probably in his early twenties, with dark hair and bandages on his neck and arms. Blake could smell some blood on him, but it was more like residual than extensive injuries. Well, even if she is curious it's not her business.

While she looked at him, he looked at her and seem to find her bow very interesting. He didn't notice, did he?

She gave him short answer.

"Book."

He was not taken aback with her shot answer, still smiled in this cheerful way.

"Of course." With last look at her bow, he look toward the counter to find that Tukson was back. "It was nice to chat with you! Goodbye~!"

This counted as chat?

She returned to bookshelf.

"Is that all you need?"

"Well yes. Thought I'd like to ask, do you have manuals for suicide? It would be most helpful!"

The stranger asked about manuals for suicide with such enthusiasm that took the poor owner aback a little. After composing himself he replied.

"…Yes, I have one such book... never thought I will meet someone interested in it…" the second part was more of mutter "Would you like to have a look at it?"

"I'd be delighted to."

How someone could be delighted to look at book about suicide?

After some time and rustle of pages she again heard the voice of the stranger.

"Thank you! It's exactly what I need! I will buy it."

After paying for his purchases young man walked out of the store.

When Blake come near the counter she heard mutters about odd young man and poor choice of literature.

Osamu was walking leisurely with his purchases in the streets of Vale, when his scroll ringed. He decided not to keep the person on the other end waiting quickly answered.

"Hello Headmaster!"

"Hello Osamu. I hope you are still in Vale?"

"Yes, why?"

"Your first assignment as Hunter came sooner than expected. Police Department of Vale require assistance in catching a criminal with active aura. He is charged for several murders and kidnapped young woman. His semblance is aerocinesis, the police could not come close without fear of suffocation. They also need to find the location of woman."

He is perfect person for the job, huh?

His voice was neutral when he answered.

"Where to?"

After receiving instruction Osamu hung up.

Time for work.

The Chief of Vale Police Department didn't know what to make out of the strange young man who was assigned to help them. When he went after criminal with carefree smile and without any noticeable precaution, he thought they would find another corpse.

Screams of anguish that came sometime after, seemingly confirm his thought.

So when Huntsman walked to them still smiling with their figurative unconscious and told them location of victim, the Chief and his men were surprised.
