That's not so, Ayu!
The true taiyaki's tail must not contain red bean jam.
If someone made it in that way in the past, he would have been scolded.

I'll never forgive you, so...
Punch!!

U...ugu?

In the past, it was served as a tea snack to carpenters, gardeners and workers who worked for the family.
At that time...

And then, without eating the tail, it was given to the dogs.
How's that?
Wasn't that an amazing information?

...washing their hands was bothersome, so they just grabbed it by the tail and ate.

You, you, youuu!

......I knew that was a nonsensical reason.
I don't quite like this Yuuichi-kun.

Hebuu!
