This is about those small writings in the rocks, right?

Yup.
So, did Yuyuboss did the reasearch or did she knew it before hand as a useless knowledge?

Some says that she knows all the food in Japan and she knows history alot, but, there is one thing I'm sure and that is she is not Akyuu, but she's Hagokoryo's princess, Yuyuko.

you gonna get stuffed later kosaga

Yuyuko's "talk" can only end in deliciousness.

I am reading the last part with "Let's talk it over (insert word for food/eating time)"

The Yuyu-sama person has a deep interest in stuff like this too, it seems, and was engrossed staring at the stone walls when we went to see the castle. People with a variety of profound knowledge really interest me!

I showed this freshly done 4-panel strip to the Yuyu-sama person while we were eating, and they quipped, "To be accurate, those are the piled stone walls, not part of the castle." :-)

Reader-added tags include "Riled up, are we, Yuyuko-sama", "You won't get away with this, Kogasa-san", and "Yuyu-sama: 'I shall teach your body the meaning of 'If the pheasant does not call, it will not be shot'." (I.e., "Better to keep quiet than to risk trouble by saying something unwise.")

The survey's ready to rock someone's world:

Let's pile up stones! Whom should we get to help?
• Get Nitori to use her mecha
• Get Big Sis Yuugi to carry them
• Get Yukarin to move them via gap
• I feel that if anyone could do it, Tenshi could!
• Make sin-sacks tow them on sledges

Yuyuko-sama has many interests, doesn't she? I wonder how much she knows about how the castle was built (personal interest of mine).

For the poll, let's make sin-sacks tow them on sledges, while I'm sitting atop a throne, cracking a whip, and laughing like Miko's HM win-pose.

I showed this freshly done 4-panel strip to the Yuyu-sama person while we were eating, and they quipped, "To be accurate, those are the piled stone walls, not part of the castle." :-)

There's a certain expected irony here.

Some of those seals look like pictures of food to me anyway, so Yuyuko's expertise doesn't seem strange.

Yuyuko-sama got pissed.....

• Get Big Sis Yuugi to carry them

Sure she won't just knock the piles over? (oni and the little kids piling stones thing)
