This encyclopedia already files tankōbon, English trades, and the UNION ARENA set. Official apparel, posters, and figures appear as Jump and anime licenses land. We do not invent a Banpresto number or a prize figure that has not been solicited. A world-tour booklet, if one ships, belongs on collectibles with an SKU. Until then the tour is a ticket.
What to buy first
The object is still the volume. Cards are a separate hobby with a partner door on the UNION ARENA page. Replica swords sold by random shops are not official just because they use a name. When a licensed figure is announced, this page will take the line. See collectibles, where to buy, UNION ARENA.
