I don't think texting beast understood the assignment. She needs to keep her code hidden.

"My" code could mean "the code I am tasked with finding," but Hinata also might've just not been paying attention.

Hidden for a week. At least.

No girl, you aren't done. You still have to protect your own code until the due date too.

It could be Noah vs Cilia, or one of the malhart kids vs another... who knows ?
The phone girl knows what is she doing ?

Imma betting on chair dance guy to win.

Good to know, Ciel. Fortunately for you, Noah does not really need any extra convincing to avoid getting touched.

(Maybe her Parasitic Eye can only be on one target, but permanently? I assumed her "eye infection" was permanent anyway)

I guess, someone doesn't have to bother protecting their code?

Something funny would be that the target for each assignment is not named, but mentioned by their code.

But it would kill a bit of the "killer game" theme.

I believe Hinata, the texter, is replying to the text. Giving her code to it somehow.

To everyone calling out Hinata not completing her assignment yet:

She apparently doesn't need to open her own envelope. That means that she can just stick it into a box and keep it on her person. Or, given how much she's on her phone, fold up the envelope and put it in her phone case, and nobody else should be able to learn her code.

If she gives her target's code now it would be interesting to see how that is graded for the target. Because that student would have never failed to defend it, the code was taken before it ever made it to the student.
