Heavenly Restriction
An innate condition inherited from Maki Zenin that strips the user of nearly all cursed energy in exchange for peak superhuman physical capability — extraordinary speed, strength, and durability that surpasses normal sorcerers.
First Appearance: Chapter 1
Tsurugi Okkotsu is the grandson of Maki Zenin and Yuta Okkotsu, and the older twin brother of Yuka Okkotsu. He inherited his grandmother Maki's Heavenly Restriction, granting him almost no cursed energy of his own in exchange for superhuman physical ability. To compensate, he wields a cursed tool katana called Honoyagi — a flame-infused blade — and channels the New Shadow Style using the cursed energy within his weapon rather than himself. Fiercely independent and driven to prove himself to the Gojo clan, Tsurugi holds Yuta's ring until he feels he's strong enough to return it to his sister.

A sword-fighting school that Tsurugi can use by channeling the cursed energy stored within his tool, Honoyagi, rather than his own. This is possible because the school's previous owner was killed by Mei Mei, opening it up to others.
Tsurugi's personal katana. Sparks generated by the scabbard infuse into the blade, causing it to ignite on fire whenever drawn. The weapon stores cursed energy that Tsurugi uses to fuel his swordsmanship.
By accepting the help of Rika Orimoto's spirit — contained within Yuta's ring — Tsurugi can temporarily fuse with her, accessing a massive surge of cursed energy that brings him to fighting parity with Maru.
