Chapter 100 Celebration Illustration and Volume 12 Cover

> Light spoiler notice: The following discussion mentions developments in the Super Star Ship competition leading into Chapter 100 based on official announcements without revealing the complete judging results.

IDOL x IDOL STORY! Officially Reaches Chapter 100

At 12:00 a.m. Japan time on November 12, 2026, COMIC FUZ published Chapter 100 of IDOL x IDOL STORY!. The official series account thanked readers for their continued support while announcing a series of activities celebrating the achievement.

The new chapter is titled Koko-chan and continues the Super Star Ship competition storyline. According to the editorial announcement, Urara takes action as the Black Star team struggles to create a significant breakthrough. A special bonus manga was also published in connection with the hundred-chapter milestone.

In the lead-up to the release, the official account ran a countdown to Chapter 100. Readers had also received additional SSS Offshot illustrations, providing glimpses of the contestants outside the competition's main storyline.

Reaching one hundred chapters is a significant milestone for a series built around the extended development of aspiring idols. Across successive evaluation rounds, the manga has continued exploring individual abilities, relationships between contestants, and the pressure of competing for a chance to debut.

Four Celebration Campaigns Announced, Starting with an Autograph Session

Alongside the publication of Chapter 100, the official IDOL x IDOL STORY! account announced four commemorative campaigns. Information about the activities has been collected on a dedicated COMIC FUZ page serving as the central hub for anniversary announcements.

The first confirmed activity is an autograph session with Shotaro Tokuno. Originally announced on November 2, 2026, the event celebrates both Chapter 100 and the publication of Volume 12, with the manga's official account sharing an application form for interested readers.

Tokuno also responded to the announcement through his personal account. The creator acknowledged his participation in the autograph event and encouraged readers to follow the additional information released by the editorial team.

The November 12 announcement confirms that the celebrations extend beyond a single event. Three additional initiatives form part of the official four-campaign lineup, but their individual details could not be independently checked in full through the campaign page. Consequently, their schedules, prizes, entry requirements, and participation procedures cannot be established from the main announcement alone.

Super Star Ship Competition Enters an Important Stage

IDOL x IDOL STORY! follows Mimi Nagisa, a former idol who abandoned her dream after her group failed to achieve success. Her life begins to change when she meets Ibuki Nanakusa, an aspiring star whose own career was inspired by Mimi's earlier performances.

Their encounter reconnects Mimi with the entertainment world she had left behind. The two subsequently enter a large-scale idol audition, where contestants must survive successive rounds of selection to form a group capable of succeeding in the music industry.

The latest storyline has reached the fourth evaluation stage, known as the Idol Festival Test. Contestants are divided into White Star and Black Star, preparing their respective performances through rehearsals, teamwork, and collaborative production.

Leading into Chapter 100, the official announcements for Chapters 98 and 99 highlighted the teams' rivalry. White Star achieved a victory with one of its performances, while Black Star continued searching for a stronger impact. That situation provides the background for Urara's decision to take action in the milestone chapter.

Volume 12 Arrives December 1 with Hibana Akagiri on the Cover

Alongside the Chapter 100 celebrations, IDOL x IDOL STORY! is preparing to publish Volume 12 on December 1, 2026. The release was announced through the manga's official account in late October, before the full hundred-chapter celebration was introduced.

The new cover prominently features Hibana Akagiri holding a microphone, with a composition built around red, black, white, and pink. The editorial team specifically connected Hibana's appearance to her character development after confronting her own weaknesses during the training camp.

According to Japanese publication listings, Houbunsha will release Volume 12 under the FUZ Comics imprint at a print price of 968 yen including tax. The B6-format book carries ISBN 9784832206731, while the digital edition is scheduled at 935 yen.

For international readers, Seven Seas Entertainment publishes the manga in English under the title IDOL x IDOL STORY!. Its English volume schedule differs from the Japanese release calendar, so the December 1 Japanese publication does not mean that Volume 12 will be available in English on the same date.

Why This Matters

1) One hundred chapters reflect the competition's long-running development

Reaching Chapter 100 highlights how the manga has developed beyond musical performances alone. IDOL x IDOL STORY! also explores elimination pressure, relationships among contestants, and personal changes throughout the Super Star Ship competition.

2) The celebrations connect the creator directly with readers

The announcement of four initiatives expands the milestone beyond the release of a new chapter. The confirmed Shotaro Tokuno autograph event offers readers an opportunity to participate directly in an activity celebrating the manga.

3) The milestone arrives shortly before Volume 12

Chapter 100 has been released only a few weeks ahead of the Japanese publication of Volume 12. Together, the announcements highlight the manga's continued serialization and the ongoing development of Hibana Akagiri and other contestants.
