The next morning.

"Yifa. You're early.

　In front of the bulletin board where they were meeting, Yifa was already looking at the notice.

''Ah, good morning Seika-kun. It seems there are many plans for the festival.

　When I look, there are more signs on the board than I expected.

''There's a lot of advertising for food stalls. Gut stuffing and steamed chicken, roasted chestnuts and fruit wine...
Hey, Seika-kun. What is this grilled fish?
I think it was a bearded sea fish, but I don't know if I could get one of these the same day.

　Nevertheless, it was unexpected.
　There are many stalls that seem to be the main occupation, since it's sponsored by the Grand Chamber of Commerce, but there are also many stalls planned by students who saw a business opportunity at the school festival.
　I thought the nobles weren't interested in such things, but.......but if you think about it, their families are also running their fiefdoms, and there are children of merchant families in the school.
　Even if they aren't delinquent students who are addicted to gambling, they still need money for something.
　Isn't that strange?

　There are a lot of shops other than food and drink.
　It is probably because this is a school where rich kids go to school, that the stalls of glasswork and hardware craftsmanship and so on. There are some oddities, such as magical stones that can be used as a medium for magic, and adventurer's guilds that deal in materials obtained from monsters.

'Wow. They sell beautiful stones. This is a flower. It's very unusual.
Hmm... hmm?

　I look at the notice Yifa looks at and nod my head.
　It's a very strange place to set up shop. It's a section of a now-abandoned research building, a place with few people on campus. It's a place where there aren't many people on campus. Selling this stuff in a place like this....

　And then it occurs to me.
　...this is a streetwalker.

　Selling trivial things like flowers and hair clips is a standard tactic of girl prostitutes who take customers in other towns' territory, but here it seems to be used simply as a cloak for them. It seems to be a way of earning money against students under the guise of the school festival.
　Don't do it on campus, no matter how much it takes.....
　No, maybe you are a student?

'Ah........this is what Amu said.......'

　In agony, Yifa points to a different signpost and says.
　It said

"Probability and Event Research Club, Presentation of Research Results----Come on, Philanthropists!　The dice and bills are waiting for you!

It's not as if he's trying to hide anything...

　I thought it was going to be written in cryptic language. It's subtly annoying that they're only making up for the beginning of the story in an apologetic manner.

　The location is a room in an abandoned research building, in the middle of the city's prostitution district. It's in the middle of the city's prostitution district.
　I mean, this compartment, various things are dangerous.
　Aside from the gambling den and the town prostitutes, there's also an apothecary's shop that deals in dubious drugs, and an alchemist's shop that sells unheard of minerals.

"...Yifa. Don't go near this area, you know.
'What...?　Uh-huh.

　Yifa, who had been staring at the betting posters, nodded hesitantly.

　I mean, I don't care about this stuff. Is there any event that could be worth money?

　The sign for the swordsmanship tournament Amu had mentioned was easy to find.
　It's the centerpiece of the school festival and the prize money is high, but it doesn't seem to be something that mercenaries and adventurers in their day jobs come out for.

　The event itself is quite good, but there's not much in the way of money to be gained.
　There is a board game tournament similar to Go, but I'm an amateur, and drawing lots is just luck...

　Oh.

Yifa. I'll play this one.
What is this?　A treasure hunt?

　What caught my attention was a treasure hunt event in the school grounds.
　The idea was to find a prize hidden in the school by following the clues that were puzzling, and it was said that you could get an ornament made of jewelry.
　I'm sure that if you sell it, you'll get a good amount of money.

I can't go out alone because there must be more than two participants.
'Yes, but are you okay?　It looks like there's a fee to enter.
I'm fine, I'm fine.

　I smile at Yifa, who looks worried, and answer her with a smile.

　I'm going to do my best to win, if I'm going to participate.

Well, let's go to class, shall we?
Uh-huh.

　Yifa looked back at the board once, and then followed me.
