A Chinese female high school student who has been working with mathematics, physics and chemistry all her life once passed through the world of "Demon Slayer: Kimetsu no Yaiba" and became a flower blooming in the garden looking at the moon. As a result, her good life without hydrogen, helium, lithium, beryllium boron, odd and even changes were ruined by cannibals in a few days...
I'm sorry, I have no choice but to practice hard and kill all the brainless cannibals!
As for why everything I said came true, I don't know!
And - why are you all starting to say weird things? !
I'm really just improving myself and killing evil spirits! ! !
Intention: growth, family affection, mutual help
