I wish we had a poster of this in our public restrooms. Though I'm a little confused as to why Kagura and Tomo are the ones explaining everything.

Cuz Osaka is a space case.....
If she said it, it would end up as a bad pun.

I guess Kagura and Tomo are giving the explanation because they form the Bonkuras trio with Osaka.
Which I guess, leads to the question of why they used Osaka?
I suppose she's arguably the most popular character, or something about her personality leads itself well to these sorts of things.
