[Orange] The last guardian of the world—Haga Mayumi—after the destruction of her world, finally broke free from the trap of immortality and entered into eternal slumber. However, when she opened her eyes again, she was reborn in another world. This world is strange. The guardians here don't get hurt or bleed, and they don't get covered in dirt like she does in battle. They always have sparkling magic to keep their clothes clean, and they can fight and fly in light dresses without revealing anything. Those guardians with brightly colored hair and clothes are called "magical girls," and it is said that no one knows their identities. Even though Haga Mayumi's childhood friend, classmates, transfer students, school doctor... and even the idol girls she saw on TV all have unusually bright hair, and each one corresponds to the hair color of a magical girl, no one notices anything unusual. It's outrageous. However, she doesn't know that the most outrageous thing in this children's world is herself—she can bleed, can move freely again in three minutes after a severed arm is stitched back up, and can resurrect from a state of minced meat after exploding into orange juice and splattering people's faces.

Chu Yuanqing swore that as a former savior, he never imagined he would one day transform into a magical girl and participate in an idol audition program because he wanted to leave his daughter an inheritance before he died. But it didn't matter; no matter how embarrassing it was, as long as he wasn't discovered, it could be pretended never happened! But who could tell him why his obedient and sensible daughter was also participating in the audition? Looking at his daughter who called him "sister" every day and bluntly said, "I'm your fan," the middle-aged office worker felt utterly devastated. Damn it, he really didn't want to compete with his daughter for a debut spot! And clearly, [human nature]...

(Orange) Miyako Amane, invited by her friend's father, came to Tokyo Metropolitan Advanced Educational High School, which values ​​merit above all else. Originally, she only planned to enjoy her school life, make some friends, and have a sweet romance. She would be content. But unexpectedly, she seems to have gained a tiny bit of fame. Thus began her strange school life: receiving love letters on Mondays, Wednesdays, and Fridays; accepting confessions on Tuesdays, Thursdays, and Saturdays; and resting on Sundays. Miyako Amane: Being liked and confessed to feels great, but can someone tell me why it's always girls who confess to me?! Sakayanagi Arisu: You'll have to ask yourself that. Remember, you're not allowed to research "Sakayanagi-specific mousse cakes" again! Horikita Suzune: Annoying guy, my mouth hurts from telling you bedtime stories, why don't you go to sleep?! What are you looking at me for? Ichinose Honami: Miyako-san is so cool! Uh... if she doesn't peek at me while I'm changing clothes next time, maybe her evaluation will be even higher~ Shiina Hiyori: I'm reading a book, please don't tempt me with food, especially that "Shiina Hiyori's favorite Type II bear biscuit" sounds so embarrassing!
