[Anime Crossover] Is It Wrong to Just Want to Cause Trouble?

The emotionless undercover auntie Tanya x a love-struck, corrupted sword boy

To destroy the being X that made her transmigrate again, Tanya chooses to go undercover in the enemy camp. She becomes the fifth master of the corrupted Honmaru at Jia-520 and keeps turning up in all sorts of worlds.

Undercover Diary

Month x, day x: The pink-haired sword keeps talking to me about conquering the world. Suspected obsessive chuunibyou.

Month x, day x: Mikazuki Munechika, supposedly one of the Five Greatest Swords Under Heaven, likes not wearing clothes. Suspected exhibitionist pervert.

After finishing her diary, Tanya opens the door. A tsukumogami with creamy golden hair is standing outside, one side of his kimono slipping down to reveal a slender shoulder. He wears a smile.

"Master? What are you writing?"

Faced with a group of sword boys who are love-struck all the time, Tanya wonders every day: Is something wrong with me, who's always scheming, and you, who are all hopeless romantics?
