Michizane Sugawara

No depiction of Michizane Sugawara has appeared in the series; he exists only as a name brought up in conversation within the prequel. Lacking any rendered image, his look and bearing are never shown.

He is identified as a vengeful cursed spirit who was human in life, counted among Japan's three greatest such spirits.

Because Michizane never appears directly and is only referenced, the story offers no window into his temperament or manner.

What it does establish is his stature: he is counted among Japan's three foremost vengeful spirits, a name that carries real weight in the jujutsu world, a figure of considerable renown rather than a defined personality on the page.

During the Cursed Child arc, Satoru Gojo notes that Michizane Sugawara is a forebear of both himself and Yuta Okkotsu, which, as a side effect, makes the two of them distant relatives. Panda and Maki Zenin add that this same Michizane sits among Japan's three foremost vengeful spirits, a heavyweight name within the jujutsu world.

The character draws on the real historical Sugawara no Michizane, grouped with Emperor Sutoku and Taira no Masakado among the nation's three great vengeful spirits. It has been suggested that the colossal cursed energy both Yuta and Satoru were born with traces back to this shared bloodline, his ancestral link to the Gojo Clan binding the two of them to him.
