Chapter 43

“I—I’m home”

“Welcome back, Onii-chan!”

“Oh, Miku. Have you been waiting for me at the door again today?”

“Un… since you said you were going on your first exploration, I was worried if you were safe…”

“Thanks for worrying about me. Because of you, I am alright, as you can see. It might also be thanks to the amulet that Miku bought for me as well.”

“U..un. I prayed to God that he would protect Onii-chan from any harm…”

“I see, I see. You cutie pie.”

“Auu…”

I start to brush and pat her head with my hands.

“H–hey, wait.. Onii-chan, you are patting me too much. Miku is no longer a kid you know…”

“Otto~ … My bad~…”

“Mou!. Be careful from next time, okay~… and so, how was your exploration today? It wasn’t too dangerous, was it?”

“It was all fine you know. I made sure to keep a good safe margin for myself afterall. Rather than that, look at this~ Miku.”

I took out 2.5 million yen from my pocket and showed it to Miku.

“Isn’t it amazing? I earned it all today itself!”

“Fueh…?”

She got shocked out looking at the wad of bills.

She touches the bundle of banknotes to see how they feel to the touch.

However, immediately after that, however, she giggles, looking funny.

“Hahaha, Onii-chan, don’t startle me all so suddenly now.”

“Arre…?”

I thought she would be more surprised.

Looking at Miku’s unexpected reaction, I got surprised instead.

“Really~ For a moment I almost mistook it was real money bills now. I got really surprised you know…, it’s bad for the heart… Ahahaha. Still, this is a really well made fake money you have there Onii-chan, from where did you get this from?”

“Ah… so, that’s why.”

Apparently, Miku thought I was setting her up for a surprise using fake money as a context.

Well, I can understand somehow.

After all, we’ve been living on the edge for such a long time, so if someone suddenly offered this large sum of money, that wouldn’t seem real, I suppose.

“Miku. This is not a fake surprise. This is the genuine article. Here, take a good look.”

I pulled out a single bill of 10,000 yen bill from the bundle and handed it over to Miku.

“Eh? This is a lie, rigjht…? You’re still trying to play a prank on me, …right?”

Miku fearfully took the 10,000 yen bill and held it up to the light bulb directly above her.

It appears that she is examining the watermark.

“Eh… hue, really? This is for real?”

And then she finally realized that the bundle I was holding was not some fake currency, but bills issued by the Bank of Japan (Nippon Ginko) itself.

That’s right, Miku. Actually, today I defeated a strong monster called Boss Monster you see. Exchanging it’s monster stone, I got this much cash as payment. Isn’t that great?

“Ah, ahaha, I see…ahahaha…”

“Arre, Miku…?”

Miku’s eyes were rolling around.

Even her feet had started to get dizzy.

“A–are you all right…?”

“~Kyu…”

“Ah…! Miku—–uuu!!!”

Miku shuts her eyes close and collapses.

I rush to support her from falling, and shake Miku to wake her up.

“What happened!. Get yourself together! Miku!”

“…”

Miku had fainted from shock.

After that, as no matter how much I shook her, she did not wake up, so, after I applied enough recovery magic to relieve her, I carried her and put her to sleep on the bed.

Maybe it was quite a bit of shock for Miku that. she remained unconscious for a good two hours even after that.
