The Strongest of Today is the first upgraded Cursed Technique in Kaizen, built straight on top of Limitless. You cannot buy it on its own. You first own Limitless, then spend a second round of materials and Yen to turn it into the Gojo V2 technique. Both stages funnel you toward the same farming spot, the Shinjuku Raid, so most of your late-game time goes there.
Unlock Limitless first (hard requirement)
Limitless is a gate, not a shortcut. Until it sits in your inventory, the upgrade option for The Strongest of Today will not appear in the Curse Shop. You buy Limitless for 1,500,250 Yen once you have gathered every material below. Most of your time here goes into the Gojo World Boss, since Six Eyes Essence drops nowhere else.
| Material | Amount | Where it comes from |
|---|---|---|
| Grade 2 Core | 50 | General enemy drops |
| Grade 1 Core | 30 | General enemy drops |
| Special Grade Core | 5 | Higher-level enemies |
| Six Eyes Essence | 6 | Gojo World Boss only |
| Yen | 1,500,250 | Farming enemies |
Upgrade to The Strongest of Today
With Limitless owned, head back to the same Curse Shop and pick the upgrade. The cost is 4,000,000 Yen plus the two raid materials. Infinity Glass and Limitless Alloy both drop in the Shinjuku Raid on any difficulty, so you are not forced into the hardest mode to finish the grind.
| Requirement | Amount | Where it comes from |
|---|---|---|
| Limitless CT | 1 | Must already be unlocked |
| Infinity Glass | 35 | Shinjuku Raid (any difficulty) |
| Limitless Alloy | 10 | Shinjuku Raid (any difficulty) |
| Yen | 4,000,000 | Farming enemies |
You know the upgrade worked when The Strongest of Today replaces Limitless in your equipped technique slot and the Curse Shop no longer offers the upgrade. If the option is greyed out, it is almost always because Limitless is not in your inventory yet, or you are short on Yen, Infinity Glass, or Limitless Alloy.
Farm the Shinjuku Raid for upgrade materials
The Shinjuku Raid is the engine for everything past Limitless. Normal difficulty needs at least Level 450 to enter, and harder modes scale up from there. Since both upgrade materials drop on every difficulty, run whatever mode your build clears consistently and repeat.
Every clear hands you Yen as a guaranteed reward. The drop rates below are based on Normal difficulty.
| Drop | Type | Drop rate |
|---|---|---|
| Yen | Always | 100% |
| Infinity Glass | Material | 23% |
| Limitless Alloy | Material | 8.5% |
| Domain Shard | Material | 1% |
| Gojo Top | Equipment | 7% |
| Gojo Robe | Equipment | 1.5% |
| Gojo Bottom | Equipment | 1.5% |
The Strongest of Today moveset
The kit upgrades the Red, Blue, and Purple set from Limitless, with each skill gated behind a mastery level. You earn access as your technique levels up through use.
| Move | Mastery | Effect |
|---|---|---|
| Lapse Barrage | 0 | Throws a blue energy ball that explodes on contact, dealing proximity damage |
| Red Rebound (Hold: Maximum Red) | 20 | Fires a Red blast in a straight line; holding it charges Maximum Red for much higher damage |
| Max Blue Barrage | 65 | Sends you airborne and spawns multiple blue balls that auto-target grounded enemies for AoE damage |
| Hollow Nuke | 90 | Plays a cutscene as you rise, fuse large balls into Purple, and slam it down for wide AoE damage |
| 0.2 Second Infinite Void (Hold: Unlimited Void) | 125 | Opens the Domain Expansion for rapid repeated damage; holding it switches to Unlimited Void for more damage and range |
Unlock the Unlimited Void Domain Expansion
Reaching Mastery Level 125 only makes you eligible. The 0.2 Second Infinite Void stays locked until you complete one more exchange. Speak with Hakaze inside Jujutsu Tech and hand over 10 Domain Shards. Once that trade is done, the move becomes usable.
The convenient part is that Domain Shards drop from the same Shinjuku Raid runs you use for Infinity Glass and Limitless Alloy. Bank them as you farm, and by the time you hit Level 125 you should be close to having all ten ready for Hakaze.
With Limitless secured, the upgrade paid for, and Domain Shards saved, The Strongest of Today goes from a long material grind to a fully kitted Gojo V2 technique, capped by the Unlimited Void domain once you finish the Jujutsu Tech handover.
