Cosplaying the Old Saber, Then Kicking the Jujutsu World's Top Brass

After cosplaying Saber, I transmigrated.

The self-proclaimed strongest sorcerer offered me a place by his side. Faced with the rotten world of jujutsu, I decided:

Roll up my sleeves and get to work!

The higher-ups: Don't you dare come over here!!!

Me: :)

"Greetings, everyone. It's time for you to step down."

I thought everything was going perfectly, but then the strongest sorcerer petulantly threw a list of victims at me, accusing me of being a flirt and saying he wasn't my only companion.

Victim list:

The Six Eyes heir

The Ten Shadows heir

The mad God of War

Businesspeople

Politicians

Friends x N

Me: Sorry, but I'm devoting myself wholeheartedly to bringing fresh air to the jujutsu world.

1. This story is very slow-burn, with alternating first- and third-person narration.

2. The protagonist is not Saber. Cursed spirits in this story must die, and Suguru Geto is guilty and needs to atone (he killed his parents; I don't hate Geto).

3. The zz storyline begins after the Haibara incident. This isn't a power fantasy, and tennis and basketball characters officially join the story (no games or plotlines from those series).

4. Some characters may have unrequited feelings for the protagonist, but the protagonist won't know and won't fall for anyone. It's mostly friendship.

Theme: People are people, no one is above another. The young should not die in their youth
