Rock in the previous chapters pushed Iruma to deactivate the traps but despite this there is a trap that Iruma cannot deactivate and this is a yandere named Shakky.
And I think Shakky has a little problem with self-confidence or maybe not. And just as men have tiger instincts, in the case of women they have a sixth sense alias feminine intuition.
Maybe Ameri and Bachiko through the story told by Jazz will draw the conclusion that Iruma would have let Rock kidnap her just so that Iruma could help Jazz with his "health problems" or something like that.
However Rock is good at computers that he jammed the signal of the surveillance cameras or Iruma worked somewhere when he was in the human world to learn how to jam a surveillance camera and what you need to do to restart/repair a surveillance camera that is jammed.
To Shakky's question to Ameri: If she is the real Ameri. I don't think Rock is so crazy as to throw himself into the lion's mouth disguised as Ameri. And if Rock really did pretend to be Ameri, Rock has to face Azz-kun; Clara and Jazz plus Shakky and plus a member of the 13 crowns Barbatos Bachiko. And if Rock were to use Iruma as a "target" if he ended up being attacked by the team, then Rock would sleep with the dead.
