[No romance + Honkai: Star Rail + Shugo Chara! + Pretty Cure + most canon couples broken up]
To graduate from the school for magical-girl mascots and become an outstanding magical-girl mascot,
Coco, reincarnated as one of the mascots, chooses the world of Ye Luoli. Her mission: raise outstanding magical girls and boys. Let's go!
I won't bash the original Ye Luoli warriors or fairies, because our heroine Coco is going to delete the entire original plot outright.
Her appearance is based on Luna from Sailor Moon, she uses the Shugo Chara! setting, and she has the powers of Pretty Cure. (The power levels in Ye Luoli go completely off the rails later on. Without a few cheats, they might not even win, so it's time to let the fairies experience the might of Asia's number-one all-girl powerhouse team.)
Things to watch out for: Most official couples are broken up, so read with caution. The official Ye Luoli content is drenched in artificial sweetness, and I just can't get into those pairings. The author mostly ships characters as friends.
The author has a day job, so updates are irregular. Characters may be out of character, and the story may read like a diary. Proceed with caution.
Theme: Love and courage are the only things that must never be let down!
Don't let the plot suck. Who are the two men and one woman in the ancient style?
