My guess is that she can text herself from the future to get information that she would later obtain. Naturally, she would have to be texting her past self the information that she had received back then, to maintain a stable time loop.

The obvious weakness of such an ability is that if her future self receives false information, her past self will as well. It also raises the question of what would happen if her future false information leads to her present death.

Not the most relevant thing, but Randall has a pretty sharp memory to be able to verify that on the spot.

Given the kind of luck Noah has, its probably his code.

@-skimmer-

I'd imagine he would consider this to be lucky, because then he wouldn't have to bother protecting it.

...I wonder what now happens to the person whose code Hinata got. They technically didn't fail protecting it, since she apparently got it before they even learned the code exists.

Just noticed that we cannot see whether also the teacher has been equipped with such a collar. You would not want to have a master spy running around unsupervised, would you?

@TaranAlvein: I feel like time travel of any kind is too much, I hope it's something else, maybe just her communicating with/hacking all the robots present around.

IMO, the students most likely to be her target would be noah, one of the malhart kids, the absentee and maybe one of the rich kids as it would be pretty funny. a bit soon to have the story take them down a peg, though.

So what happens to the student whose code this was? Based off this the code was taken before the student received it so you can't really say they failed to protect it.

@Skimmer I doubt it? It could be, but only if it makes for a more interesting story. Otherwise, he probably aimed her at someone he needed humbled or pressured.

Ookay, "Student Number" wasn't mentioned at any point for this task. Where did she get this information? From this "Education Center" student database or what?

If Justopea bought random computer related tech from Magilante and Hinata got the info just because the JSP does not have a clue about operating it correctly that would be hilarious. Like, her power could be: "I just know how to use devices, please do not ask me to fix your printer or why your browser runs slowly. The resident 'techie'"

L33T indeed

@Straightbackward, the Student Number was mentioned in page 4544, I had also thought the students were given a code and the name of their target. Upon double checking, the students here were only given the student number of their target, leaving each student to figure out both the identity of their target, as well as their target’s secret code.
