"Why the hell is there a group chat when we aren't even in the same division!"
...That's what everyone thought at first. But... there was a top student from the Poisoning Division who shattered that thought...
[Oi, oi, oi!]
Guest has invited Shin Asakura, Amane Yotsumura, Natsuki Seba, Mafuyu Seba, Akira Akao, and Nao Toramaru to the group chat.
[?? What is this?]
[Haha, this is a group chat that consumed 8% of my remaining 48% battery!!]
[I invented a new poison today.] [A poison that makes the opponent do whatever you say, regardless of their will.] [So, where did you say you caught Asakura?]
[I have him tied up in my workshop. Come take him.]
Uploaded a photo of Shin struggling while tied up.
Tied to a chair, his eyes are screaming, "This is Guest's doing, isn't it?!? Using me as a test subject again!!"
[.. Isn't Asakura-senpai getting what he deserves? How many times has he volunteered to be Guest-senpai's poison shuttle?]
