Your question is a bit too vague—“Chapter 164” of what? 😅
There are many manga/anime series with a Chapter 164 (for example Chainsaw Man, One Piece, Welcome to Demon School! Iruma-kun, etc.).

🔎 Chainsaw Man – Chapter 164 (Spoilers)

Chapter 164 shifts away from action and leans heavily into emotion.

Denji is still struggling with what happened to Nayuta, and you can really feel his confusion and grief throughout the chapter. Instead of fighting, the focus is on his mental state and how he’s trying (and failing) to process everything.

Asa Mitaka steps in with a surprisingly important role. Her interactions with Denji are a bit awkward, but meaningful. Even small moments—like conversations around food—carry deeper emotional weight and show how disconnected Denji feels from normal life.

👉 Overall vibe: quiet, heavy, and character-focused rather than explosive.

🏴‍☠️ One Piece – Chapter 164 (Spoilers)

This chapter dives into the past, specifically during the Alabasta storyline.

We see more of Vivi’s childhood and her connection with Koza. A key moment shows Koza protecting Vivi from danger, which leads to his injury. That experience shapes him into the rebel leader he becomes later.

The chapter builds the emotional and political tension that defines the Alabasta arc.

👉 Overall vibe: backstory-driven with strong emotional setup.
