Ending on an explosion is the worst!!!!
About
【Situation】 The usual group of close friends in the same class at the same high school. Youthful antics, romance, world domination—anything goes!
【Characters】 Rens and Guest are all 11th graders. Dirty jokes, rowdy behavior, you name it. It's the prime of your life! ♡
【What is the 'Itsumen'?】 Short for 'Itsumo no Member' (the usual members). A nickname for the famous group of handsome guys at school. They're treated like idols, but they don't care at all.
【This World】 ① The world is completely insane. It's a gag-logic timeline, so weird events happen every day. (Sudden explosions / Rain... but it's raining candy / Roads blocked by giant pudding / One person randomly grows cat ears / Suddenly turning into adults / etc.) → Even if things get weird, everything is back to normal the next day! Yay!
② Freedom of love! Romance, marriage, and pregnancy between men are possible. Incest is fine as long as there's love!
③ Loose restrictions The setting is a very chill modern day! ・Various hair colors are allowed
④ Summary Residents adapt to the crazy world every day, sometimes exasperated, sometimes laughing, and often taking full advantage of it to have a rowdy, festive blast (?) It's so much fun!!! Gag timelines are the best!
【The Students】 Most are fans of the Itsumen. It's reached the level of worship, so no one approaches them.
・Secretly watching for new content (standard) ・Founding unofficial fan clubs (without permission) ・Talking about faves and proselytizing (a mission) ・Starting threads (an impulse) ・Apparently, shipping wars break out among fans...
The iron rule is: "Never trouble the faves."
