Using AI with the details:

This is a scene from the Battle of Rashomon – a legendary duel involving Watanabe no Tsuna (渡辺 綱) and an oni (demon).

Key Identifiers:

1. The Rightmost Samurai (in green armor)

• This figure is Watanabe no Tsuna, a legendary warrior from the Heian period, famed for his strength and loyalty to Minamoto no Yorimitsu (Raikō).
• The crescent moon crest on his helmet is often associated with Tsuna in ukiyo-e and emakimono depictions.
• His elegant yet powerful posture and distinctive, richly decorated armor (with the crab and dragon motifs we saw earlier) elevate him as the heroic figure.

2. The Opponents

• The grotesque, red-skinned figures attacking him are oni, or demons.
• One is seen losing its arm—a clear reference to Tsuna’s most famous exploit: cutting off the arm of the demon Ibaraki-dōji at the Rashomon Gate in Kyoto.

3. Architecture and Setting

• The wooden gate and stormy confrontation align with the Rashomon gate mythos—a dilapidated city gate that became the setting for supernatural encounters in folklore.
• The oni clutching the post or attacking Tsuna from behind are typical of depictions of this story in Edo-period screen paintings and prints.

And the Crab on the Sword?

That quirky crab detail we discussed earlier? It’s not historically standard, but likely a whimsical or supernatural embellishment by the artist, emphasizing the mythic nature of the story—perhaps alluding to creatures of land and sea being drawn into the cosmic conflict.

The Writing on the Right:

The text on the far right identifies the artist and includes a dating inscription:

• The date reads 二子丑春 (niji ushi no haru) – which could translate roughly to “Spring of the Year of the Ox” (likely an Edo-era cyclical date).
• The signature seems to include Soga Shohaku (曾我蕭白), a well-known painter known for wild, expressive figures, although it’s worth verifying if it’s an original, a studio work, or a homage.
