Toji's Heavenly Restriction in Kaizen: Unlock Steps and Skill Breakdown

Toji's Heavenly Restriction is a melee-focused cursed technique in Kaizen built around raw physical power rather than cursed energy output. It borrows heavily from Toji Fushiguro's fighting style, including a cinematic finisher that recreates his infamous takedown on Gojo.

Quick answer: Buy Toji's Heavenly Restriction from Dr. Shiro Kato in the school courtyard for 3,000,000 Yen, 50 Grade 2 Cores, 35 Grade 1 Cores, 25 Heavenly Cores, and 15 Restricted Essences. The Heavenly Cores and Restricted Essences only drop from the Hidden Inventory Raid.

Unlock requirements and where to buy it

The cursed technique is sold through the Permanent Cursed Techniques tab in the in-game shop. You can reach it by talking to Dr. Shiro Kato, the NPC in a lab coat standing to the left of the Principal in the school courtyard, or by pressing the red Shop button on the left side of the screen.

You will need the full material cost on hand before the purchase option becomes available.

Hidden Inventory Raid, the only source for key materials

Both Heavenly Cores and Restricted Essences drop exclusively from the Hidden Inventory Raid. There is no alternative grind path for these two items, which makes the raid the bottleneck for the unlock.

The raid has tiered difficulties with their own level gates. Easy opens at Level 220, while Nightmare, the top difficulty, requires Level 535. Beyond CT materials, the raid also drops cosmetic gear.

  • Yen
  • Heavenly Core
  • Restricted Essence
  • Toji Top
  • Toji Bottom
  • Darkness Robe

Two titles are tied to the raid. Toji's Challenger requires contributing at least 20% damage across 65 Toji kills on any difficulty. Heavenly Restriction Incarnate requires the same 20% damage threshold across 75 Nightmare clears and is the only way to earn that title.

All five abilities and their mastery unlocks

The kit has one starter move plus four abilities that unlock as you raise the technique's mastery level. The capstone is the cinematic ultimate, Cursed Ambush.

SkillMasteryEffect
Dash Fury0A forward dash punch with two stacked charges. Damages the target directly in front of you.
Rock Flurry25Launches you into the air, slams down at a targeted spot for AoE damage, then rains rocks on the area.
Chained Severance70Swings a chain for three consecutive hits. The final swing is a wide AoE sweep that can pull grouped enemies in.
Split Soul Annihilation90Makes you briefly untargetable and unleashes a fast single-target flurry of slashes that is very hard to counter.
Cursed Ambush100The ultimate. You blink-step forward, and the first enemy crossing your path triggers a cutscene followed by a heavy slash-and-stab combo.

Cursed Ambush is the move that recreates Toji's inverse spear of heaven finisher. It pulls a target into a cutscene, which means it is strong against PvE bosses but easier to dodge or cancel in PvP since you need to walk into an opponent during the blink animation.


Best clan pairing: Zenin

The Zenin Clan is the natural fit. Its signature passive, Determined, directly buffs Toji's Heavenly Restriction, and its stat spread leans into melee and weapon damage, which is where this technique does all its work.

  • +10 Melee
  • +10 Cursed Energy
  • +9 Stamina
  • +13 Defense
  • +6 Weapon
  • +3.75% Cursed Energy DMG
  • +3.75% Health
  • +8% Max Cursed Energy

Because the kit is built around physical strikes at close range, pour stat points into Melee to scale DPS. Stamina matters too, since Rock Flurry, Chained Severance, and Split Soul Annihilation all consume a noticeable chunk per cast.

Playstyle notes

The technique is an aggressive, close-range kit with strong PvE farm potential. Chained Severance can hook multiple enemies at once, making it the go-to opener against grouped mobs, and Split Soul Annihilation's untargetable window lets you burst down priority targets without interruption.

In PvP, Cursed Ambush is the weakest link because the blink startup is easy to read. If it gets cancelled, the cooldown still applies, so treat it as an opportunistic finisher rather than a combo starter.

🗡️
Note: Invest in HP alongside Melee and Stamina before running the Hidden Inventory Raid. The boss hits hard, the arena is small, and you only get one life per attempt.
