Spider-Gwen: Her Big Debut | The Manga has officially begun serialization on KadoComi. Created by Ryusei Yamada, Chapter 1-1 went live on October 10, 2026, following the earlier reveal of the Spider-Gwen project under the MARVEL｜KADOKAWA initiative.

Spider-Gwen Announcement and Series Visual

Gwen Stacy Returns to a Double Life

The new series retains the central Spider-Gwen premise. Gwen is a high-school student and drummer for The Mary Janes who gains extraordinary abilities after being bitten by a radioactive spider.

Away from Ghost-Spider's action, her personal problems remain important. Gwen has to navigate school, her band, and a difficult relationship with her police-officer father.

Part of the First MARVEL｜KADOKAWA Wave

Spider-Gwen did not launch alone. MARVEL｜KADOKAWA opened five series on October 10, covering Spider-Man, Deadpool, Venom, Iron Man, and Spider-Gwen.

KADOKAWA has described the collaboration as an effort to deliver new Marvel stories through Japanese manga expression, giving the line room to approach familiar characters from different angles.

Ryusei Yamada Brings Spider-Gwen Into Manga

Ryusei Yamada already had a connection to Marvel before this project, including a Captain Marvel illustration for MARVEL SWIMSUIT SPECIAL.

His Spider-Gwen manga now brings the character's superhero action and younger everyday life together in a distinctly manga-oriented presentation.

Next Update Scheduled for October 22

KadoComi currently lists October 22, 2026 as the next update date.

KADOKAWA has also confirmed plans to publish collected volumes after serialization, but a release date, price, page count, and ISBN for Spider-Gwen have not yet been announced.

Why This Matters

1) Spider-Gwen gets a new manga interpretation

The Marvel character is now being handled directly by a Japanese manga creator through an official KADOKAWA collaboration.

2) Gwen's life outside the costume remains central

Her band, school, family, and relationship with her father remain part of the story rather than simply background for Ghost-Spider action.

Traitor

3) It is part of Marvel's new manga expansion in Japan

MARVEL｜KADOKAWA launched with five titles at once, creating room for different approaches to Marvel characters.
