Track 1

Trash bags, tissues, aluminum foil… What else do we need…?

Master, we are short of bathroom detergent. Based on HAMA House’s consumption trend, the remaining amount will last approximately one week. Proposal: I recommend purchasing these items at the drugstore up ahead, which is currently holding a sale.

Ah right, bath detergent! I almost forgot about getting some.

Thanks, Kinari-kun! You’re such a lifesaver helping me out with shopping.

Please leave both the transportation of the goods and the collection of information on the best nearby deals to me. Furthermore, it seems that this establishment offers a lottery ticket for every 3000 yen you spend.

A lottery ticket! I wonder what sorts of prizes they have? Would it make everyone back at the dorms happy if I win something good?

The first place prize is a Premium-Grade Wagyu Beef Shabu-Shabu Set. Calculating the mean number of customers this drugstore has, as well as the number of winners allotted for each prize, the probability of winning is about 0.12%.

0-0.12%...

On the other hand, the second prize is a year’s supply of laundry detergent. The probability of winning this prize has risen to 3.4%.

If that’s the case, we might be able to win that! We just need to spend over 3,000 yen, right? Stocking up on supplies wouldn’t hurt anyway…!

Let’s go stop by, Kinari-kun!

Yes, Master. I will accompany you.

One draw for the lottery, yes? Please rotate the handle to the right.

Alright…! Our eyes are set on that year’s supply of laundry detergent! Maybe that premium-grade wagyu too!

Good luck, Master.

……Unfortunately, you lost…! You got the sixth prize, a sparkler~ Here you go!

Ah, thank you very much.

I didn’t get either the detergent or the wagyu… Sorry, Kinari-kun.

……

? What’s wrong?

It is nothing. So this is also a form of ‘firework’... I have saved information on it, but it is the first time I have seen one.

I see. Then, do you know of other ways you can have fun with sparklers?

What sort of “other ways” could there be?

…Then, Kinari-kun, if it’s good with you, why don’t we go for a detour on the way home today?
