Zenigata filed a report to the Student Council President requesting foran arrest warrant... whatever passes as an arrest warrant within school jurisdiction stating details, or what he happened to see of the brawl, and also the significant destruction of a wall that would need to be repaired, rubble to be cleared etc. (It was mentioned that Zenigata ran to the scene of Satoshi's awakening; if he didn't see Satoshi, he saw the ruined walls and etc, and he saw Satoshi and Cho in the infirmary. All this happened in classy's posts.)
The ECDA do not know about the exosuit, they only know that Satoshi was implicated in the incident that afternoon.
Of course you realise I'm just BSing the first part about filing a report and filling in the blanks with logical conclusions so that I don't need to rewrite my post. :V
Kalad, however and whether or not you want to change Kaze-Ou is up to you since I obviously didn't think it was important enough to PM you about.
