ONE PIECE magazine: Ace, Sabo, Luffy A5 Cousin Size - Techo Lineup

ONE PIECE magazineAce, Sabo, LuffyA5 Cousin Size

2025 New
ON SALE OCT 1

The Hobonichi Techo is back with another collaboration with ONE PIECE magazine, which dives into the world of the hit manga series One Piece. This techo cover features a scene from the childhood of the main character Straw Hat Luffy, described in “Brothers’ Sake Cups” of the 60th volume of the comic series.

Ace, Sabo, and Luffy are sworn brothers. The design incorporates their respective image colors: orange (Ace), blue (Sabo), and red (Luffy).

When Ace and Sabo were ten years old and Luffy was seven, they exchanged cups of “Brothers” Sake and formed a bond. This flashback depicts the days when they slept, ate, fought, and laughed together while training to become stronger.

On the inner cover, you will find a unique graphic printed that is not included in the comics; it is a scene from “Luff,” a specially created episode by Eiichiro Oda for Vol. 1-3 and 12 of the ONE PIECE magazine.

The right-hand pocket is silkscreen-printed with the silhouette of the three characters.

A powerful scene from “Luff” is also featured in the center of the inner cover. The left-hand pocket features a collaboration logo for ONE PIECE magazine and the Hobonichi Techo.

The spine of the cover has the letters ASL and is designed to recreate the look of ONE PIECE magazine’s book spine.

We recommend pairing this cover with the Hobonichi Pencil Board for A5 Size (Memories - Trafalgar Law), which offers a comfortable writing surface under your current page.

We’ve also made a series of ONE PIECE magazine x Hobonichi Techo stationery items that are fun to use with your techo.

In the Hobonichi Techo 2025 lineup, the Cousin book comes in either English or Japanese.

*The English book is only available as the January-start version.

A heartwarming flashback scene

Our collaboration with ONE PIECE magazine is now in its third year. For this edition, we have incorporated results of the reader survey into the book, covers, and stationery. We wanted the techo covers to link with the readers’ favorite scenes and make them want to look back at the One Piece stories again.

The “Luff” episode that Eiichiro Oda specially drew for the ONE PIECE magazine inspired me to feature the three brothers, Ace, Sabo, and Luffy. I was impressed with the luxury of being able to read the story of the three grown up that was specially made for ONE PIECE magazine, and wanted to create something based on it.

The front cover features a reminiscence of the three little brothers that will touch your heart just by looking at it. On the inner cover, the three brothers are depicted as dignified adults. This extraordinary combination was made possible by collaborating with the ONE PIECE magazine.

The One Piece characters all have their precious memories and essential parts of their lives, and we are moved by how they live with them. We created this item for you to fill your 2025 edition of the Hobonichi Techo with your favorites, treasures, and precious memories.

Please Read Before You Buy

In order to provide you with the most satisfaction for your product, we've compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Please be sure to read this information carefully before placing your order.

Actual specifications may vary from listing: Each item is individually assembled and sewn by hand by a factory worker. Best efforts are made to ensure consistent sizes and specifications, but there may be slight differences.
Color and print may vary slightly: This material is first printed or dyed and then later sewn onto the cover. While colors are designed to be consistent, there may be uneven coloring or slight shade variances between covers. This may also happen across a single cover, such as a pocket compared to the rest of the cover. In addition, on rare occasions, there may be small black or white dots visible on the print. This is an unavoidable aspect of the manufacturing process.
Cover may contain variations in stitching or loose lining: Due to the structure of the cover that opens flat 180 degrees, exterior stitching areas may appear puckered and lining material may be loose.
Pen holders are rigid at first: The pen holders are rigid at first, making it difficult to insert pens. You can speed up the breaking-in process by rolling the pen holders in your hand.

Pen holder fits pens up to 13.5 mm wide: The pen holder is designed to perfectly fit the 12.2 mm (0.48”) diameter Jetstream pen offered as a free Hobonichi Store Exclusive. Pens with certain shapes and materials may be difficult to pull through the holder. The holder can fit pens up to 13.5 mm (0.53”) in diameter.
Avoid storing in hot and humid places: Please avoid storing your product in hot, humid places or placing it atop other objects for long periods of time as this may result in lower quality and color stains.
Silk printed image may peel off over time: The silk print may eventually peel or come off with daily use. If using a Cover on Cover, the silk print may stick to the plastic and eventually come off with it from the constant contact.
