Sent by their mistress, Kiryuin Satsuki, the Four Devas of Honnoji Academy take on UA's finest!
A couple of scenarios:
Scenario 1 - "We only need the Four of us to carry out Satsuki-sama's will!"
The Four Devas rock up to UA and announce their intention to conquer the school. All four of them have their final regalia and are ready to throw down. No teachers are present at UA, only the student body is there. No one can leave the grounds and environs of UA voluntarily.
Can they crush all resistance and annex the school for the glory of Honnoji?
Scenario 2 - "Face the full might of Honnoji's power!"
The Four Devas are backed up by all named life fibre weapon wielders shown in the series to attend Honnoji. This excludes Satsuki and Ryuko but Mako is definitely there and getting hype. They also get 100 grunts with one star uniforms as grunt back up.
To help things though, UA get the support of the core members of the League of Villains prior to the most recent arc. Shirageki and Gigantomachia are not present.
No teachers again, final regalia for the Devas. Can UA fend off these invaders?
Scenario 3- "It takes guts to bring the fight to us! Come on!"
The student body of UA stage an attack on Honnoji Academy itself. The hero team get three days of observation, strategising and prep time. They can pick the time and method of engagement but they must subjugate the whole Academy. in addition to the Four Devas and the regular student body, Satsuki and Ryuko are present but they are limited to their power levels as of their first real duel. Ryuko cannot go berserk.
Can UA strike back at these high fashion fanatics?!
Which school reigns supreme?
