The package says it contains "toys"? Maybe you've got the wrong address?

But it's listed as official SCHALE supplies for Sensei, with a scheduled delivery time though.

I accidentally scheduled the delivery for Yuuka's duty day!!!! What do I do now!!!!?

Sensei, take the fall for me, pleeease! Didn't you help me just now!!!?

Don't be ridiculous! Learning to protect yourself is part of your studies!

Haah, haah... Where did they run off to!?

Has anyone seen Sensei and Koyuki!?

If you're looking for Koyuki, she went that way.

Really!? Thanks for letting me know!
