This episode sets the stage for the anime's finale. We see Izumi searching for Hijikata to deliver Okita's message, while simultaneously being pursued by Ran, who seeks Okita's revenge. The story unfolds as Hijikata loses battles and the Shinsengumi is wiped out, but ultimately, there's something he still wants to do. It's a fast-paced episode, full of action, emotion, and a touch of nostalgia. It's canon within the storyline and quite entertaining to watch.
