Major “Ace of Diamond act II” Original Art Exhibition to Be Held in Osaka! Collaboration Cafe and Canon Collaboration Booth Also at Tokyo Exhibition

To celebrate the 20th anniversary of the manga series, the major “Ace of Diamond act II” Original Art Exhibition, following its September event at Ikebukuro Sunshine City, will be held in Osaka at Shinsaibashi OPA from November 29 (Sat.) to December 14 (Sun).

The “Ace of Diamond” series (“Ace of Diamond”, “Ace of Diamond act II”) by Yuji Terajima has been serialized in Weekly Shonen Magazine (Kodansha), and the total number of printed comic volumes has exceeded 45 million copies. The anime “Ace of Diamond act II” is scheduled to air its second season in 2026.

At the original art exhibition, more than 300 monochrome and color original artworks will be on display, reflecting on the fierce battles for a spot at the Summer Koshien tournament. Attractions include the “Fierce Battle Theater,” where you can experience the intensity of the West Tokyo Final game through thrilling video, as well as a fully recreated Seido High School baseball clubroom. In the clubroom area, visitors can enjoy special, original daily-changing stories performed by the luxurious cast, including Eijun Sawamura (voiced by Ryota Ohsaka), which can only be heard at this event.

Additionally, a collaboration cafe will be open at the venue, where customers who order from the menu will receive one random “Baseball Ball-Shaped Acrylic Name Tag” from a total of 12 types. The cafe can be used even by those without an exhibition ticket.

Furthermore, at the Tokyo venue, there will be a collaboration corner with Canon’s mini photo printer “SELPHY,” offering a random print experience. Visitors can print commemorative mini cards from all 12 types of designs. Also, in the merchandise area, purchases of at least 5,000 yen (tax included) in a single transaction will come with a special bonus of one random “mini shikishi” (mini autograph board, 12 types total).

Tickets include a regular general admission ticket, as well as a bundled admission ticket with exclusive goods—a uniform pin set. Admission bonuses include one random “Ticket-Style Card” (out of 12 types) for all paid attendees.

Event details will be updated as necessary on the official website and official X (formerly Twitter).
