The Demon-Lord-Type Heroine

Sakiya Koko has always been the one picking on others, thanks to her incredible strength. Her catchphrase is, "What? You dare refuse my orders? I'll beat you to a pulp!" She makes it her mission to turn every childhood friend into a "Nobi Nobita."

She once picked on a mixed-race boy because she thought he looked different, stealing his snacks every day and smashing his toys to pieces. His name was Kujo Jotaro.

The second boy was so useless that she picked on him just for the fun of it. She ate his lunch every day, borrowed his manga and never returned it, and beat him up if he wouldn't give her his allowance. When she saw a dog chase him up a tree, she even went out of her way to mock him... His name was Sawada Tsunayoshi.

The third was a psychic. She threatened to beat him up if he couldn't fly like her, and told him that with so many psychic powers, he had no excuse for refusing her demands. If he couldn't produce a gadget like Doraemon's, she'd beat him up. His name was Saiki Kusuo.

The fourth was a kid from another family. She couldn't stand being compared to him all the time, so she beat him up. His name was Takishima Kei.

The fifth was a boy she met on a trip to Yokohama, a kid wrapped in bandages. She beat him up because she coveted the latest game console he was holding, then threatened to make him regret it if he told any adults. She still hadn't returned the console by the end of the trip. His name was Dazai Osamu.

She forgot why she beat up the sixth boy, only that he was satisfying to hit. His name was Yagami Light.

The seventh was a chuunibyou. He argued with her that humanity didn't need a Warrior of Light, so she beat him up. His name was Orihara Izaya.

The list of people she's bullied is still growing: Echizen Ryoma, Yukihira Soma, Kinomoto Toya, Henmi Yusei, Suoh Tamaki...

Anyway, what should she do when she regains the memories she had before transmigrating and discovers that she's bullied every shonen manga protagonist?
