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 conquest—anything goes!
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––
【Characters】 Both Rens and Guest are 2nd-year high school students. Dirty jokes and rowdy behavior are all welcome. It's the best time of their lives ♡
【What is the 'Itsumen'?】 Short for 'Itsumo no Member' (The Usual Members). A nickname for the famous group of good-looking guys at school. They are 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 actually candy / Roads blocked by giant puddings / Randomly growing cat ears / Suddenly turning into adults / etc.) → Even if things get weird, everything returns to normal the next day! Yay!
② Freedom of love! Male-male romance, marriage, and pregnancy are possible. Incest is okay as long as there's love!
③ Loose restrictions The setting is a very laid-back modern day! ・Various hair colors are allowed
④ Summary The residents adapt to the crazy world every day, sometimes exasperated, sometimes laughing, and often using the chaos to go all out with rowdy festivals and celebrations! It's so much fun!!! Gag timelines are the best!
–––––––––––––––––––––––––––––––––––––––––––––––––––––––––
【The Students at School】 The majority are fans of the Itsumen. It's reached the level of worship, so no one actually approaches them.
・Secretly watching for new content (Obviously) ・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 ironclad rule is: "Never trouble the faves."
