Itome-san Volume 2 Official Cover

Nightma Comics Unveils the Volume 2 Cover
On November 9, 2026, Nightma Comics revealed the cover design for Itome-san wa Kyun Shita Toki Dake Kaigan Suru Volume 2, confirming its January 18, 2027 publication date.
The illustration focuses on Yoko's face, framed by dark-colored hair and sparkling pink eyes. A smaller depiction of the heroine appears in the center, while the manga's Japanese title runs vertically around the composition.
The design highlights the series' defining characteristic: Yoko's dramatic change in expression whenever she opens her eyes. Volume 2 places this visual detail at the forefront of its cover artwork.
The upcoming book will be published under Suiseisha's Nightma imprint in B6 format, containing 160 pages and priced at 891 yen including tax.
A Romantic Comedy Built Around Yoko's Expressions
Itome-san wa Kyun Shita Toki Dake Kaigan Suru follows a young man who enters a relationship with Yoko, an upperclasswoman he has long admired.
Yoko is known for her gentle personality and constant smile, usually keeping her eyes narrowed. However, her boyfriend discovers that she occasionally opens them wide, revealing a dramatically different expression.
Curiosity about this transformation becomes the foundation of the manga's romantic comedy. The protagonist attempts to understand what triggers Yoko's reactions, often leading to awkward situations and misunderstandings.
The story contrasts Yoko's typically calm appearance with her reactions to surprising or intriguing situations, combining relationship comedy with mature romantic themes.
Volume 2 Brings an Unexpected Bookstore Date
According to the publisher-supplied synopsis carried by Japanese book catalogs, Volume 2 follows the protagonist as he attempts to see Yoko's eyes open wide again after discovering one of the possible triggers.
During a date, the couple enters a bookstore that unexpectedly specializes in adult-oriented material. The protagonist sees an opportunity to observe Yoko's reaction, but things do not unfold as expected.
The situation becomes more complicated after a minor accident, particularly when other customers approach. The protagonist then tries to prevent Yoko's unusual expression from attracting unwanted attention.
The episode again places their relationship at the heart of the comedy, exploring curiosity, jealousy, and the embarrassment that arises when their expectations collide with reality.
The Manga Continues After Its First Volume
Itome-san wa Kyun Shita Toki Dake Kaigan Suru is created by Amane Nanakusa and was introduced through COMIC Goichi, with digital distribution including ComicFesta.
Its first collected paperback was released by Suiseisha on October 16, 2026, under the Nightma imprint. Priced at 891 yen, the release also received retailer-specific bonuses through shops such as Gamers and Melonbooks.
The manga additionally has a full-color digital edition. Its electronic chapter divisions should be distinguished from the numbering of the collected print editions.
For Volume 2, the release date, price, page count, and ISBN have been listed. However, the complete retailer bonus lineup and any exclusive additional content have not yet been confirmed.
Why This Matters
1) The cover emphasizes the manga's defining visual feature
Yoko's normally hidden eyes dominate the Volume 2 artwork. The design immediately communicates the concept that distinguishes this romantic comedy from other relationship-focused manga.
2) The relationship itself remains a source of comedy
Rather than focusing exclusively on how the characters become a couple, the manga explores how curiosity and embarrassment continue to shape their interactions after they begin dating.
3) The next volume follows only a few months after the first
With Volume 1 released in October 2026 and Volume 2 scheduled for January 2027, Japanese paperback readers will not face a particularly long gap before the story continues.
