From manga characters to a single visual theme
Katsura’s manga credits include Wingman, Video Girl Ai, I’s and ZETMAN. He also contributed original character concepts and hero designs to TIGER & BUNNY.
For this collection, Genkosha describes an emphasis on shape, posture and the lines created by clothing. The released artwork moves between textured gold backgrounds, pale surf and a sparse interior with a metal railing. White underwear, black swimwear and turquoise fabric provide contrasting colors and surfaces across the illustrations.
The finished cover takes a more graphic approach: a white field, bold Positive Sensitive lettering and a central illustration of shorts worn over dark tights with a paw-shaped opening. The accompanying gallery contains that cover and eight separate artwork previews.
Retailer bonuses use different illustrations
The announced extras vary by seller and purchase route. They are not a combined set included with every copy.
| Retailer |
Announced offer |
| Genkosha Store |
One exclusive illustration Instax print bearing a reproduced Katsura signature. This is not a handwritten autograph. |
| Shosen Grande |
An exclusive card using an illustration based on Moe Iori. |
| Shosen Book Tower |
A different exclusive Moe Iori illustration card. |

Melonbooks separates its poster offer from its signed-book lottery. The publisher states that signed-book lottery winners do not receive the A3 poster; orders through the poster-bearing listing are excluded from that lottery. Check the chosen retailer’s application and purchase conditions before ordering.
Katsura’s signing event has its own lottery
A signing session with Katsura is scheduled for December 20, 2026, at 2 p.m. JST, at Shosen Book Tower in Akihabara, Tokyo.
The event lottery requires purchase of the designated application product between October 23 at noon and November 8 at 11:59 p.m. JST. Winners receive admission; unsuccessful applicants receive an ordinary book. Both receive a lottery-specific Moe Iori illustration card, distinct from the regular store designs.
Winners must bring their purchased book and official identification. Katsura will sign the designated book and add the attendee’s name. No appearance by Enako, Ise or Iori has been announced.
Shosen also offers a separate signed-book lottery, with applications closing November 25 at 11:59 p.m. JST. Winners receive a signed copy, while unsuccessful applicants receive an ordinary copy; both receive the lottery-specific card. This purchase does not grant signing-event admission. Applications to both Shosen lotteries are permitted, but an applicant can win only one.
