About this collection

The Seidou Battery

The heart of the series is the push and pull between wild southpaw Eijun Sawamura and the sharp catcher Kazuya Miyuki, with speedster Yoichi Kuramochi rounding out the infield. Merchandise skews heavily toward Act II goods, so most finds are character acrylic stands and stand figures drawn from web and kuji lotteries.

Kuji Prizes and Everyday Carry

Beyond display pieces, the line runs into Tekutoko keychains and charms, pale-tone series stands and Battery Box mail-order exclusives. Because so many are numbered prize-lottery items, provenance and condition matter - the grade records both for every genuine piece we list.
