Pre-order Announcement and New Cover

A Summer Fashion Magazine-Inspired Cover

The new book adopts a presentation closer to a Japanese fashion magazine than a conventional illustration collection.

A large Dokitora masthead sits at the top alongside “August 2026,” while the four central characters pose together in light summer outfits dominated by white and denim.

Smaller headlines are placed across the cover as if they were editorial fashion features. The largest line promotes a midsummer “winning coordinate” theme.

The approach fits Dokitora’s focus on character personality and everyday fashion rather than presenting its heroines only through standalone pin-up artwork.

All Four Trump Musume Return

Trump Musume revolves around four women whose designs draw from the four suits of playing cards.

The principal characters are 可愛川 心, 國富 菱夏, 黒羽 三葉, and 貴美島 冬香. They differ in age, school or work life, personality, and fashion.

The commercial manga Trump Musume no Susume explains that the four originally meet by chance while searching for a “phantom cake” at a Western-style restaurant called Full House.

Despite coming from different backgrounds, repeated encounters gradually turn them into a close group of friends.

The C108 cover once again puts all four characters at the center rather than shifting the focus toward a guest character or licensed property.

The New-book Set Includes Original Playing Cards

A badge printed on the cover promotes a bonus reserved for the new-book set.

The visible item is an original Trump Musume playing-card set, using character artwork within the card designs and accompanied by an original card case.

It is an especially fitting piece of merchandise for a cast whose visual identities have always been based on hearts, diamonds, clubs, and spades.

The latest post does not provide a complete specification for the cards or the entire merchandise bundle.

Card count, materials, full artwork, bundle pricing, and any additional set contents should therefore wait for the detailed Melonbooks listing or Harakenshi’s complete C108 menu.

Harakenshi-shi Is Attending C108 on Day 2

Harakenshi previously confirmed that his circle Harakenshi-shi has been assigned to:

• Day: Sunday, August 16, 2026
• Hall: West Hall 1
• Block: hi
• Space: 41ab

Comic Market 108 itself runs on August 15 and 16, 2026, at Tokyo Big Sight.

Fans planning to purchase the book directly from the artist will therefore need to attend the second day of the convention.

Online pre-orders have already opened through Melonbooks. Harakenshi noted that shipping may take some time because the final submission was completed comparatively close to the event.

Dokitora Has Been Running Since C101

Dokitora predates the upcoming C108 release by several years.

The first book was released for Comic Market 101 at the end of 2022 as a B5 full-color illustration book built around the four playing-card-themed girls.

Its numbered follow-ups include:

Worm In Rotating Land

• Dokitora 2: C102, August 2023
• Dokitora 3: August 2024
• Dokitora 4: December 2024
• Dokitora 5: C106, August 2025
• Dokitora 6: December 2025

The accessible text from the latest C108 announcement does not expose the full Melonbooks product title. This article therefore refers to it simply as the new C108 Dokitora book rather than assigning an unverified volume number.

Trump Musume Has Also Become a Commercial Publication

Harakenshi’s original characters have expanded beyond the doujin series.

KADOKAWA published Trump Musume no Susume on December 23, 2024. The A5 full-color volume runs for 144 pages and combines existing illustrations with 78 pages of newly drawn manga.

The commercial edition gives the four characters more room to interact and explains how their friendship begins despite their differences in age and daily life.

Harakenshi also released his first professional art collection, TOUCH Harakenshi Works, through Genkosha on July 27, 2026.

The 144-page B5 artbook includes Trump Musume alongside licensed work for properties including Romancing SaGa Re;univerSe, Cardfight!! Vanguard, and Fate/Grand Order.

That makes C108 a return to Dokitora’s doujin roots only weeks after the release of Harakenshi’s first major commercial artbook.

Why This Matters

1) The cover fully commits to the magazine concept

Headlines, cover-girl typography, and fashion-editorial styling turn the illustration into something closer to a fictional August fashion issue.

2) All four main characters share the spotlight

The artwork emphasizes their different looks while keeping the complete Trump Musume group together.

3) The bonus returns to the playing-card concept

A real playing-card item is a natural extension of characters originally designed around the four card suits.

4) It follows immediately after TOUCH

The C108 release arrives shortly after Harakenshi’s commercial artbook, giving fans another project focused specifically on his original characters.
