Maki is so strong because of her Heavenly Restriction , which strips her of cursed energy and, in exchange, pushes her body to the absolute peak of human (and basically superhuman) potential.

Heavenly Restriction = Broken Physique

In Jujutsu Kaisen, Heavenly Restriction is a condition where a person gives up something (like cursed energy) to gain an overwhelming talent in another area.

Maki was born with almost no cursed energy, and after her twin sister Mai’s death, that remaining bit was completely erased, “completing” her Heavenly Restriction and unlocking her full physical power.

Key effects:

  • Superhuman strength on par with Toji Fushiguro, another Heavenly Restriction monster.
  • Superhuman speed and reflexes, to the point she can move faster than many characters can even perceive and can react to bullets.
  • A “body of steel” that can tank lethal attacks and keep fighting.

Story-wise, the trade‑off is simple: no “magic,” but a body that makes sorcerers look fragile.

Why She Feels So OP Now

Before her full awakening, Maki was already physically gifted but held back by even a tiny amount of cursed energy interfering with her restriction.

When Mai dies and uses her last strength to remove Maki’s cursed energy completely, Maki’s limits disappear: she one‑sidedly wipes out the Zenin clan’s elite fighters and is directly compared to Toji in his prime.

Some big feats:

  • Slaughtering the Zenin clan, including top fighters, almost solo.
  • Easily handling special grade threats once she’s fully awakened.
  • Outspeeding and overpowering fast sorcerers like Naoya Zenin after his evolution.

How Her Strength Works in Fights

Maki isn’t just raw stats; she’s a technical monster too.

  • Master of weapons: She can use a huge variety of cursed tools and normal weapons, from polearms to special-grade tools like Playful Cloud and Dragon Bone.
  • Enhanced senses: She can perceive tiny changes in air density and temperature, letting her predict movements and even “step” on invisible surfaces in the air to reposition mid‑fight.
  • Near invisibility to sorcerer senses: With no cursed energy, she’s hard to detect and gains natural advantages against things that rely on sensing cursed energy.

This combination makes her feel unfair: enemies rely on cursed techniques and energy perception, while she just blitzes them from blind spots.

Why Fans Call Her a “War God”

In the manga’s later arcs, characters literally describe Maki as a war god after her full transformation, saying she has become a being on Toji’s level.

She’s an anomaly in the power system: in a world built around cursed energy, she proves that a pure physical specialist with Heavenly Restriction can sit at the very top. So when you’re asking “how is Maki so strong,” the short in‑universe answer is:
she traded away cursed energy and, after Mai’s death, fully awakened a perfect Heavenly Restriction, giving her a superhuman body, insane senses, and lethal weapon skill that let her rival the strongest sorcerer‑killers in JJK.

TL;DR: Maki is so strong because her completed Heavenly Restriction removed her cursed energy and turned her into a physical and sensory monster on Toji Fushiguro’s level, letting her steamroll sorcerers who rely on techniques and energy.
