After Graduating College, the Strongest Magical Girl of Her Generation

After graduating from college, Lin Yan was preparing to work as a trainee teacher when he received some news: his little sister, who was a magical girl, had gone missing.

As he went to the association to ask around, a monster appeared, and the magical girl who came to fight it was soon in danger too.

At the critical moment, he made a contract with something calling itself the [Magical Girl System], obtained a Soul Gem, and transformed into a new magical girl.

After kicking the monster to death and leaving in style, a legend began to spread in Haicheng about a mysterious magical girl codenamed [Radiant Sun]:

They say that among monsters, the magical girl codenamed Radiant Sun is a terrifying figure who can make even little monsters stop crying at night.

As for the magical girl herself, in order to find her sister, she now spends her days teaching and educating students, and her after-school hours fighting monsters.

Lin Yan by day: Yes, you. Come up and solve this difficult math problem.

Lin Yan after work: Since I've inherited my little sister's profession, how can I stand idly by? Any monster that eats into my free time can just die!

And Lin Yan at night...

"You little brats, I'm begging you, try to hold back and stop climbing into my bed! I have class tomorrow!!"
