Let's change that to "EVERYTHING is a serious business" (more fun that way)
Don't forget: The club is the result of merging various club together. They each have their own Serious Stuff moment.
Characters in plan:
Teacher in Charge: hardworking...etc in Vantier Project but down here, she can sleep through a train wreck, she used to be part of Napping Club while in school and she is actually still as lazy. Just don't ask her why she end up teaching in ISA (touchy subject. Something got to do with neither this nor that).
Club Leader: she don't have much friends which is why she came up with this idea, Rivalry with ACE club even though the members are younger than her
Inspiring Combat Chief:
used to be part of a cooking club which got disband (bake stuff for everybody)
Computer nerd: spend the whole day play eroge. Used to be part of Computer club
That two girls: Probably the lowest rank in the totem (they are kind of the errand girls who got played around by others). Used to be part of Literature and Calligraphy club
Cosplay maniac: third year student, as known as the legendary Club Assassin due to being in various club, and all of them are disband. (the truth is actually opposite, she joined to prevent the Clubs from being disbanded)
Edit: Note: Her religion is Jediism.
Others:
Feminist Club, a club which bash males. For most of the time, everybody ignore them. Plotting to get rid of Ichika and squash any amount of pride males have.
