I absolutely love the Osano-Osoro rivalry and Kizano-Aso friendship you have going on :P such great dynamics I didn't think of before :D I might also see some Amao-Oko friendship too
film club info(my version): you can frame rivals for crimes by telling them to do something for a film or using editing, this could be an elimination method for mida rana, as you can record evidence of her being a cougar and get her arrested, it also gives you an excuse to record senpai you can make films with other students in them to increase your reputation, you will also have access to heavy equipment and props from the theater club, and you can also carry around a weapon under the guise of using it for a film the theater club and film club do collabs a lot, an event involving that could be a perfect way to get rid of kizana, maybe she's been treating a film club member like a servant and they'll help you kill her as revenge, or you could just drop and sandbag on her and frame said club member, as they would have a motive the club item-symbol-thing is a headset with the school crest on the earcup, which info chan can hack and use to communicate with you directly, and participating in club activities can increase your tech skills
