Hello! Sir Tiny, this is ako.

(I don't want to write Mr nor Ms.
I don't have to know your gender.
But tonight, I'd like to call you with some title with respect.
...maybe strange English I wrote....)

Last night, I took a rest.

All tax-payers need it....this season......sigh....

So I got a "RIPOBITAN GOLD" just now !
I tried to find two katakana tonight again.
Harder than before !!

Yes! Thank you so much I could find it !
Finally I could !!

But,,,,,

〉N　　10000 right
〉10000 ○ here shape like upside down fermata

〉　　　B11111111

Mmmmmm......

When I first read this hint, I thought about "upside down fermata".
"Fermata is, I am not sure but,,,is a misic code, maybe..."

It's just like a half moon and a dot inside,,, right ?
Then "upside down fermata" is like.... like.....
a dot in a kind of bowl.....?

So I tried to watch carefully the 10000yen bill.
But where ?

Sir Tiny wrote "10000 right".
I first thought that means "10000" near FUKUZAWA's head !
But if so, why did Sir Tiny write "B1111111" below....
I was confused....

Oh ! How fool ! I got it !

There are two arabic number 10000 on the face of 10000 bill.
At first I carefully looked around one of "10000" near FUKUZAWA.

This was a big mistake !
Sir Tiny means the left one !

Now I understood what you mean.
I found it, katakana N.

Yes, it is like "upside down fermata"..v(^^)v

From tonight on, I can sleep deeply.
I can take a deep breath.

Thank you !
