Detective Conan Card Game is the official trading card game for the long-running Japanese mystery manga and anime franchise. The current trend formed around Shippu no Kirameki, the CT-P09 expansion scheduled for release on April 25, 2026, and a launch campaign from the official TCG account.
The first trigger was the official April 23 campaign post. Fans were asked to follow the Detective Conan Card Game account and quote-post with the campaign hashtag for a chance to win a Chihaya Hagiwara card signed by creator Gosho Aoyama. The prize was limited to three winners, which made the post feel less like a normal promotion and more like a collector event.
The timing explains why the topic moved quickly. The campaign arrived two days before the new expansion, when TCG players and Detective Conan fans were already checking card lists, rarity information, and release details. The local analysis also flagged two-color Mystery Rare cards as a new feature in the set, giving collectors another reason to watch the launch.
Chihaya Hagiwara is the character context non-Japanese readers need. She has been highlighted in Detective Conan story material, including the Sunday Webry episode page and a Shogakukan comic volume built around Chihaya and Jugo's matchmaking-party storyline. That made the signed card feel meaningful to character fans, not only to card-market watchers.
What to watch next is the April 25 release window. If Shippu no Kirameki sells through quickly, if opening posts highlight the new Mystery Rare cards, or if resale prices move around the signed-card campaign, the topic can keep traveling beyond the first official post.
