Jujutsu Kaisen: Who Stole the Shikigami from My Ten Shadows?

[Jujutsu Kaisen, No System, Heavenly Restriction, No Female Lead, Reincarnated from Birth]

The strongest of the old era vs. the strongest of the modern era

Sukuna: Your head is held too high, too low, too far left, and too far right.

Kanzaki Naoto: Sukuna, you're the challenger here. King of Curses, do you still have enough credit to borrow against?

Kanzaki Naoto: Everyone else who transmigrates into Jujutsu Kaisen gets the Ten Shadows Technique. I got Shadow Manipulation, which is... well, you know. Who turned my Ten Shadows Technique into Shadow Manipulation? What am I supposed to do without my elephant vs. house? What about my Mahoraga?

Megumi Fushiguro: Isn't Shadow Manipulation just an inferior substitute for the Ten Shadows Technique?

Kanzaki Naoto: You think my Shadow Manipulation is a joke? Naruto, One Piece, Bleach, Fairy Tail, Fullmetal Alchemist, lend me all your shadow powers!

Satoru Gojo: I looked up your family tree because of your technique, and sure enough, you're distantly related to the Zenin Clan.

Kanzaki Naoto: The Zenin Clan? As long as I'm not a Fushiguro, I'm good.

Megumi Fushiguro: Got a problem with my surname?

Kanzaki Naoto: No, I just finally understand why my Conqueror's Haki always feels like it's awakening whenever I see Maki.
