It looks like you’re asking about when Yuji was added or became playable in Jujutsu Shenanigans (JJS). The results I found mention Yuji-related custom movesets and Yuji-focused content, but they do not clearly state the original release date for Yuji in JJS.

What I could verify

  • Yuji appears in recent JJS-related guides as a custom moveset option, including “Modulo Yuji”.
  • I also found a YouTube result from February 20, 2026 referencing “NEW JJS YUJI CHARACTER,” which suggests Yuji was newly featured around then, but the snippet alone is not enough to pin down the exact release date.
  • A Reddit post from March 1, 2026 refers to players starting when the game still had “yuji and gojo only,” which shows Yuji was already in play by then.

Best answer from the available info

Yuji was definitely playable in JJS by early March 2026, and he appears to have been newly introduced around late February 2026 based on the February 20 video result.

Why it’s still a bit fuzzy

The search results I found point to Yuji’s presence in the game, but none of them give a clean official launch date for his addition. So the safest answer is: late February 2026, with confirmation that he was already in the game by March 1, 2026.

TL;DR: Yuji seems to have come out in late February 2026 and was already playable by March 1, 2026.
