"The Secret Shizuoka Green Tea"?

"Shizouka Mys-tea-ry Juice" Originally, "Cha-renji Juice", punning "challenge" with "cha" (tea) and the "renji" of "orenji" (orange). And yes, she says, "Shizouka" rather than "Shizuoka".

Thank you for waiting.

It's just regular green tea!

And this is just green tea and orange juice!!

But it's tasty.

Why?!

And I was expecting the flavors to be like what you'd get from a punishment game.
