#Weekly Short Short 'Unusual Names: Nine out of Ten 753' Let's Live Laughing 2 (491 characters in body)

I found something a bit interesting online. I called out to my girlfriend, who was preparing dinner while humming a tune.

Hey, got a second?

What is it?

You know how there are surnames that contain numbers? For example, there's a rare one written with a 'one' that's read as 'ninomae' (before two), and one written with a 'nine' that's read as 'ichijiku' (fig). What do you think is the largest number included in a surname?
Hmm, that's hard. Wait a second.
She stopped cooking and came over to my side.

What could it be? Hmm... Oh, I've got it!

What, what?

I'm pretty sure it's nine out of ten, 753!
She had a look of complete smugness on her face.

Wrong. Not even close. By the way, is there actually anyone named 753?

There is. My favorite idol is named Shimekake, written with the characters for 7-5-3. I was sure I had the right answer.
Well, what about names like Sengoku (thousand stones) or Manda (ten thousand fields)?

Oh, you're right. Anyway, what's the correct answer?

It's written with the characters for hundred, thousand, ten thousand, and hundred million, and it's read as 'Tsumoru'.

Wow, what an amazing name!

Still, you had such a smug look on your face earlier. 'Nine out of ten 753,' you said.

Oh, stop it.

Saying that, we both burst out laughing.

I love that innocent side of her so much.

I'm participating in Nika Tahara's weekly short short challenge. I had so much fun writing one that I decided to write another one featuring the same couple.
