Akaza’s Flashback and a tense battle
The battle begins when Tanjiro makes a surprise appearance, combining Hinokami Kagura techniques such as “Fire Wheel” and “Fake Rainbow” to injure Akaza. Giyu then entered the fray, activating Water Breathing techniques and even experiencing the Demon Slayer Mark awakening to deal with Akaza’s wave of ferocious attacks as well as trying to defend Tanjiro. Giyu and Akaza fought fiercely, unleashing punches and shockwave attacks with great precision, but Giyu’s sword was eventually broken by Akaza’s Bell-Splitter technique.
Meanwhile, Tanjiro had been studying his father’s “Transparent World” teachings-an ability that allowed him to see his opponent’s movements slowly and without any killing intent. In this moment, he managed to pull out Akaza’s sword and make a fatal cut with Kagura’s Hinokami: Setting Sun Transformation, separating Akaza’s head from his body.
Conclusion
Akaza’s story emphasizes the humanitarian theme that true power is the ability to keep a conscience and protect the weak, not destroy.
The Infinity Castle arc adapted into this trilogy movie brings great dynamics: the final war, team strategies, inner conflicts, and learning moments about life and death. It is worth noting that the movie “Infinity Castle – Part 1: Akaza Returns” is released in Japan starting today Friday, July 18, 2025 and will be shown in other regions such as Indonesia on August 15, 2025.
Overall, Akaza’s battle against Giyu and Tanjiro is one of the emotional and dramatic high points in Demon Slayer, showcasing the pinnacle of ninja techniques as well as an affirmation that true power comes from the heart and courage to protect others.***
