Synthesized from 2 Yomimono stories · updated Oct 22

Samurai Kobo, which operates the esports team Crazy Raccoon, is part of the joint project behind the trading card game Xross Stars with Game & Co., a subsidiary of Brave group. The game launched on August 22, 2025, and now sits in the top 10 for share of Japan's domestic TCG market, according to a Media Create survey covering August 2025 to July 2026. The specific ranking and share percentages were not disclosed.

Xross Stars turns VTubers, streamers, and esports players into cards across agency lines. The first set featured 24 people, mainly from VSPO!, Crazy Raccoon, and Neo-Porte, and the roster has since grown to 72 talents through the fourth booster pack, Grand Resonance. Production is led by producer Atsutoshi Kubo of Game & Co. and chairman Daichi Takano of Crazy Raccoon, with Shota Yasooka as lead game designer and Sekappy as development partner.

The next piece of promotion is a first for the game at this level: the first terrestrial TV commercial for Xross Stars, airing from October 20, 2026, nationwide except in some regions. The 15-second spot features Ryosuke Yamada in two personas, the artist Yamada and the streamer LEO, who is affiliated with Crazy Raccoon. The two appear together on screen for the first time. Yamada took the stage as LEO at an announcement event on October 19 and described the costume as settled through discussion with his own input.

LEO joins Xross Stars as a leader card in Booster Pack Vol. 5 Ignition Vortex, due October 30 at 475 yen per pack of eight cards or 5,700 yen per box of 12 packs. The fifth booster pack has 16 leaders. The commercial will also go up on YouTube on October 20, with a making-of plus interview video planned for later release.
