I have some information on this print – and I am familiar with the story of Katsugoro being cured after his wife prayed for him at Hakone falls. But I don’t know anything about this revenge story, or how women got involved in the fighting. Fuji arts says “young warrior Iinuma Katsugoro fighting his sworn enemy, who had murdered his brother.”
Also the date – 1840s is all I can get with just the Kiwame and the two different Kunisada signatures
The signatures are "Kōchōrō Kunisada ga" (left and "ōju Kunisada ga" (center and right). The title of the print is "Righteous Revenge at Hakone" (Hakone reiken ki no adauchi - 箱根霊験記の仇討). The publisher's logo is by Ezakiya Kichibei; date c. 1835/40.
Some informations about the story are here: https://www.toshidama-japanese-prints.com/item_1446/Yoshitaki-Jitsukawa-Saburo-as-Inuma-Katsugoro-and-Arashi-Kichisaburo-as-Takiguchi.htm
Many thanks! Kuniyoshi did a very similar print, but without the women: https://www.fujiarts.com/cgi-bin/item.pl?item=900115
The image (and others I know) is somewhat blury but the names (from left to right) should be:
Hatsuhana x (初花x), Iinuma Katsugorō (飯沼勝五郎), Seguchi Kōzuke (滝[or 瀧]口上野), Iinuma tsuma Hatsuhana (飯沼妻初花), shimobe Fudesuke (下部筆助).
Lucienne means in scene the wife Hatsuhana is killed by Kōzuke but her ghost is defending linuma who is fighting Kōzuke. I think that makes sense. :-)
Many thanks!
