Sakamoto Days [UE19BT] | English 16 Packs + Foil Box Topper

The Union Arena Trading Card Game Booster Pack: Sakamoto Days (set code: UE19BT) is the English release of the Union Arena Sakamoto Days booster set from Bandai, launched on May 29, 2026. Union Arena is Bandai's "Common Rules Trading Card Game" — a crossover TCG that brings characters from different anime, manga and game IPs onto a single shared ruleset. The Sakamoto Days set brings the hit TV anime — based on Yuto Suzuki's ongoing Weekly Shonen Jump series — into Union Arena for the first time, starring the legendary ex-hitman turned shopkeeper Taro Sakamoto alongside Shin Asakura and Lu Shaotang from "Sakamoto's", plus the elite assassins of The Order including Nagumo, Shishiba and Osaragi.

For Sakamoto Days and TCG collectors, UE19BT is a heavily collector-focused release. The headline chase cards are the foil-stamped autograph cards signed by six members of the Japanese TV anime voice cast — Tomokazu Sugita (Taro Sakamoto), Nobunaga Shimazaki (Shin Asakura), Ayane Sakura (Lu Shaotang), Ryota Suzuki (Heisuke Mashimo), Taku Yashiro (Shishiba) and Saori Hayami (Osaragi). The set also features eight brand-new illustrations created exclusively for Union Arena (Sakamoto, Shin, Lu, Mashimo, Nagumo, Shishiba, Osaragi and Takamura), alt-art parallel cards, and a limited serial-numbered Action Point card seeded at an extremely low pull rate in limited quantities. On top of that, every booster box includes a foil box topper — one of five foil design cards.

For Union Arena players, the set adds full deck-building support for the Sakamoto Days roster — from Sakamoto's deceptively easy-going shop crew to The Order's elite hitmen. Under Union Arena's shared ruleset, Sakamoto Days decks can battle Jujutsu Kaisen, Solo Leveling, Bleach, Hunter x Hunter, Chainsaw Man and every other Union Arena IP in crossover matchups. Card breakdown: 30 Commons, 28 Uncommons, 12 Rares and 10 Super Rares (80 card types in total) plus 12 Action Point (AP) card types, with alt-art variants on top.

Box contents: one sealed Union Arena Trading Card Game Booster Box: Sakamoto Days [UE19BT] containing 16 booster packs plus one foil box topper (1 of 5 designs). Each booster pack contains 12 cards spanning Common, Uncommon, Rare and Super Rare rarities, with AP cards at low pull rates. Language: English. Publisher: Bandai. Condition: Factory sealed.

Ideal for Sakamoto Days fans collecting Taro Sakamoto, Shin, Lu and The Order in card form for the first time, Union Arena TCG players adding a brand-new IP to their crossover lineup, collectors hunting the voice-cast autograph chase cards and the serial-numbered AP card, anime and Shonen Jump fans expanding into Bandai's crossover Union Arena line, and as a gift for Sakamoto Days fans in the UAE and wider GCC. Recommended for ages 13 and up.
