Tsuburaya Ultraman Card Game UNION of Dreams [EXB01] Japanese Booster Box

Experience the first-ever crossover in the ULTRAMAN CARD GAME with Extra Booster 01 UNION of Dreams [EXB01], featuring the popular TV anime SSSS.GRIDMAN.

The set introduces characters such as Gridman and Gridknight, with cards designed around the abilities and personalities of the main SSSS.GRIDMAN cast. EXB01 can also be used to build a complete deck using cards from this product alone.

Many high-rarity cards feature newly drawn illustrations by creators who worked directly on the SSSS.GRIDMAN anime, while extremely rare cards with handwritten signatures from four cast members may also be randomly inserted.

Each sealed Japanese booster box contains 16 packs, with 8 Japanese-language cards randomly enclosed in each pack.

One of EXB01’s biggest collector highlights is its newly drawn artwork from creators who worked directly on the anime.

Official contributors include:

• Masayuki Gotoh — Gridman Design
• Tsuyoshi Nonaka — Assist Weapon Design
• Hiroki Mutaguchi — Heroic Animation Chief
• Mayumi Nakamura (TRIGGER) — Sub-Character Design

These creator-drawn cards give UNION of Dreams a much stronger connection to the original anime production than a standard crossover booster.

EXB01 also includes extremely rare cards featuring handwritten signatures from four SSSS.GRIDMAN cast members:

• Yuya Hirose
• Hikaru Midorikawa
• Yume Miyamoto
• Reina Ueda

These cards are randomly inserted at a very low rate and are not guaranteed in any individual pack or booster box. 

UNION of Dreams is more than a themed expansion. It is the first collaboration product in ULTRAMAN CARD GAME history and introduces a completely new Yellow card color.

The set is also designed so players can build a deck using only EXB01 cards, while the combination of creator-drawn artwork, original GR/SSSSP rarities and handwritten cast signatures gives it strong collector appeal.
