Among the many characters that are expected to debut in theDemon Slayer: Kimetsu no YaibaInfinity Castle movie, these are going to have the most far-reaching influence both on the story and character development of the main cast.
1Koyuki
Keizo’s Daughter
Koyukiwas an unfortunate girl who was born with a disease that made her bedridden for most of her life. She faced tragedy after tragedy throughout her life and lived a very painful existence. Koyuki personally did not do anything that influenced the human-demon conflict directly, but her existence itself became a source of pain and emptiness that drove one of the most powerful characters in the series.
Koyuki’s appearance is expected to be brief, but her impact is going to be huge. She will unknowingly influence events decades after her existence and shape circumstances that no one could have predicted.
2Keizo
An Empathetic Dojo Master
Keizowas atalented martial artistand an expert in the Soryu fighting style. Many decades ago, he used to run a dojo and was empathetic enough to not only accept a convict named Hakuji as his disciple but also entrusted him with the responsibility to look after his daughter.
Keizo’s decision had far-reaching consequences, and he ended up influencing events that shaped countless lives.
3Kotoha Hashibira
Inosuke’s Mother
Kotoha Hashibirahas had a partial appearancein the series already. However, not much is known about her life.Inosuke’s dream reveals that shedid spend time with her child when he was young, but it is unclear how long the mother-son duo were together.
Kotoha’s full appearance doesn’t happen untilthe Infinity Castle Arc, and for good reason. Her life was far from perfect, and she was caught up in an evil cult that threatened the lives of her loved ones. Kotoha’s debut will offer a better understanding of the tragedies that unfolded before she was separated from her son and give Inosuke the much-needed closure he never got.
4Uta
Yoriichi’s Wife
Yoriichi Tsugikuni is regarded asone of the best swordsmen to have ever lived. But despite his lasting legacy and influence onthe Demon Slayer Corps, not much is known about the tragic hero. Although he has made a few brief appearances, Yoriichi’s personal life is shrouded in secrecy.
My dream was to live a quiet life with my family in a small house where we would sleep side by side. I would be close enough to see the beloved faces of my wife and child, and close enough to reach out and take their hands. That would have been enough. But even that did not come true. Demons exist in this beautiful world.
However, the story so far has strongly hinted that Yoriichi struggled with loss, as he is often shown in a state of pensive sadness and barely ever smiles. These factors set the stage for his wifeUta’s debut, which is expected to reveal the dark secrets about his life and the emotional toll of his sacrifices. Uta’s appearances are going to humanize Yoriichi and share an unseen side of his personality that will change the viewers' perception of the legendary swordsman.
5Akeno Tsugikuni
Mother Of The Strongest Demon Slayer Ever
Akeno Tsugikunilived during the Sengoku era and was the mother of perhaps the two most influential figures who went on to reshape the seemingly endless human-demon conflict in unthinkable ways. She was known to be a pure-hearted and kind woman driven by a desire to give her children the best life possible.
Akeno’s debut is going to give fans more context for the overall lore and add emotional depth tothe Tsugikuni family’s tragic legacy. It will also offer a glimpse into the life of the two strongest beings to have ever existed in theDemon Slayeruniverse.
6Kaigaku
The New Upper-Rank Six
Gyutaro and Daki left a voidin the Twelve Kizuki after they died in the Entertainment District. The Upper-Rank Six position was left vacant until Zenitsu’s old bully ran into Kokushibo and accepted his offer to become a demon to save his life.Kaigakuhad always been a crookedand untrustworthy person whose desire for self-preservation made any ethical considerations secondary.
Although he has appeared as a human in the anime before, Kaigaku is yet to make his debut as a demon. The series foreshadows his future clash with Zenitsuin the Hashira Training arc, setting the stage for an epic battle that will be filled with action-packed fight sequences and emotional tension. While there will be many memorable clashes in the upcoming arcs, very few can match the emotional weight and bitterness of Zenitsu and Kaigaku’s fight. As a demon, Kaigaku’s role may not get as much screen time as other characters, but he is all set to leave a lasting impression on the viewers with his cruel and twisted worldview.
