Summary
A terrorist plans on killing himself along with the american soldiers, but Onikobe using stealth technology appears in front of him and cuts him down. The soldiers then enter and see the dead body and one of them realizes it must have been ninja doing. Another comments he wants to see the ninja, but is told he will die if he sees it. Little after the mission, Onikobe receives a call from Kato who asks what Marici version is the uniform Onikobe wears and Onikobe tells Kato its 3.5. As Kato hangs up, he wonders why a low ninja like Kuro got the new version 4.0, as usually new versions are always first deployed on the front lines.

Meanwhile, Kuro investigates the hoodie, but can't find something. Eventually he notices a connection for 9V battery, but as he doesn't have one, he goes into Oono's apartment to take one from his sex toys. He connects the battery and puts on the hoodie, but nothing happens. He guesses it may be password protected and mentions a couple of words, but again nothing happens. He decides to go sleep, but in that moment notices that his arm turns invisible along with the rest of his top half.
