Volume 2 and the Voice Bonus

Shiori Izawa Performs All Three Main Heroines

The bonus places Shiori Izawa in the roles of Nadeshiko Kawahara, Ayame Kakitsubata, and Momoka Sakura. Rather than assigning separate performers, the promotion highlights Izawa's ability to distinguish all three personalities.

The QR-accessible messages were written by Kushizaki specifically for the campaign. Weekly Shonen Magazine confirms that the cards come in three designs and are distributed randomly.

Distribution Begins With Volume 2's Release

The bookstore promotion begins on November 9, 2026 at participating retailers. Each eligible purchase receives one card, customers cannot select the design, and distribution ends once individual stores run out of stock.

The audio remains accessible through November 8, 2027, giving the digital portion of the bonus a substantially longer availability window than the physical card distribution.

One detail remains inconsistent between official pages. Kodansha's PR TIMES release lists Volumes 1 and 2 as eligible, while Weekly Shonen Magazine's dedicated page specifies Volume 2. Buyers seeking the bonus with Volume 1 should therefore confirm eligibility with the participating store.

Shiori Izawa and Kushizaki Signed Campaign

A related official campaign is also underway. Fans who follow @omaegaBM and repost the designated campaign post between October 16 at 12:00 and October 23 at 23:59 JST can enter for a signed shikishi featuring autographs from Shiori Izawa and Kushizaki.

Three winners will be selected, with eligibility restricted to participants residing in Japan who can receive the prize domestically.

From One-Shot to a Second Volume

Kushizaki's work originally appeared as a one-shot through Magapoke before developing into a serialized manga in Bessatsu Shonen Magazine.

The story centers on Hanamura and three female classmates who become involved in a small school mystery. Its approach is character comedy rather than serious mystery, using the situation to build everyday interactions between the four leads.

Volume 1 launched in June 2026 and received an immediate reprint according to Kodansha. Volume 2 follows five months later with a more elaborate voice-driven promotion.

Why This Matters

1) One performer handles all three heroines

The campaign lets Shiori Izawa differentiate Nadeshiko, Ayame, and Momoka within a single bonus project.

2) Kushizaki wrote new material for the audio

The bonus messages are specifically written for the promotion rather than simply reusing manga dialogue.

3) The physical and audio benefits have separate availability windows

The cards are limited by store inventory, while the voice messages remain accessible until November 2027.

Closing

Omae ga Yattan Daro! Volume 2 expands Kushizaki's manga beyond the printed page by giving all three main heroines dedicated audio performances from Shiori Izawa.

The physical bonus depends on store participation and inventory. Because the two official Kodansha pages differ regarding Volume 1 eligibility, readers specifically buying the first volume for the benefit should confirm the current conditions with the retailer.
