Event story summary pt.1
Story starts with Suzumi bullying sukebans with flashbangs as usual, one of them accuses the Vigilante Crew of being not too dissimilar from them, since she has no legal jurisdiction like the JTF claiming her acts of violent is without conviction
The same night, Shimiko overhears talks of an amusement park will be expecting "mass casualty" and "becoming a huge mess" from a couple helmet gang members, as they were approaching Shimiko's position, she slipped away and ran into Suzumi
Shimiko ask Suzumi to catch the helmet gang members but Suzumi, still hanging on to the sukeban's accusation, turned down the request and suggests that they should inform JTF instead, so they heads to Hasumi to report the incident
After hearing how Suzumi didn't deal the situation first hand, Hasumi asked if Suzumi was feeling unwell, after getting the reply of "No", she then checked the calendar and confirm the date and it is in fact not April's fool
Hasumi then tells Suzumi and Shimiko that there's not much the JTF can do in this situation since only half of the amusement park is Trinity's territory, and if they send in any JTF forces, the helmet gang can simply retreat to Gehenna's side, of which they have no jurisdiction in. She then ask Suzumi and Shimiko to sneak in undercover and do some reconnaissance, since they still don't have a clear picture of what the helmet gang is planning
On the way home, Suzumi and Shimiko bump into Reisa and she offers to help, and came up with the idea of cosplaying as characters from the magical girl kids show that will be taking place in said amusement park tomorrow, since Reisa herself is a fan of the show; Suzumi as Thermite White and Reisa as Thermite Pink, with Shimiko being the main villainess Error
The day of the show, Hasumi sends Mashiro as spotter and Sensei as emotional support to help, then Suzumi and Reisa got mistaken as actual staffs and is asked to perform on stage, half way through the show Rabu and goons shows up and Suzumi and Reisa starts pursuing them
Rabu being Rabu, starts running the moment she sense she's being targeted, and start heading towards Gehenna's territory, Suzumi and Reisa fails to stop her since they can't use their flashbang and shotgun because kids are surrounding them thinking it's still part of the show
Rabu realizes something doesn't add up and don't get why they're being treated as the bad guys so she play into the show and pretend to be defeated and slipped away while Suzumi and Reisa are recovering
Sensei then ask Suzumi to trauma dump and she explains she's doubting her own creed because of what the sukeban said to her that night, and reveals that she used to be a member of the JTF, but quit soon after enrolling since she doesn't fit in with the strict system, and sucks at maintaining conversations with the crowd
