Yotsuba Nakano – Negi Haruba SSSP Illustration

Vol.8 features a new Yotsuba Nakano illustration created by Negi Haruba, the original author of The Quintessential Quintuplets.

The SSSP treatment includes a foil-stamped creator signature. Extremely rare first-print copies also feature an individual foil-stamped serial number between 001 and 099.

The first-print serial-numbered card is a limited variant, not a guaranteed inclusion. Later printings may feature the SSSP without the serial number.

GSP and Original Manga Artwork

Two GSP card types featuring Yotsuba are included in the expansion, using original illustrations by Negi Haruba with different card treatments.

The set also features colored manga artwork, newly illustrated anime designs, and illustrations inspired by The Quintessential Quintuplets puzzle game.

Voice Actor Signature Cards

Selected cards feature reproduced foil-stamped signatures from the Japanese voice cast:

• Kana Hanazawa – Ichika Nakano

• Ayana Taketatsu – Nino Nakano

• Miku Ito – Miku Nakano

• Ayane Sakura – Yotsuba Nakano

• Inori Minase – Itsuki Nakano

These are printed foil-stamped signatures, not individually hand-signed autographs.

Bushiroad has announced a first-print box bonus featuring one randomly selected mini illustration board from 10 available designs.

Five designs feature original full-color manga illustrations with reproduced handwritten-style name details.

The first-print bonus is separate from the 60 booster cards. Its inclusion depends on the printing and distribution batch supplied.

Collector Note: The numbered Yotsuba SSSP card and first-print illustration board are different collectible features. The numbered SSSP is an extremely rare card variant, while the illustration board is a first-print box bonus. Neither should be confused with guaranteed contents of every printing.
