Ace of Diamond ‘Fighting Spirit’ Diamond Motif Ring Now Available with Character Name Engraving

The TV anime “Daiya no A actII -Second Season-” has announced the release of a “Diamond Motif Ring.” Pre-orders are currently being accepted at the U-Treasure Online Shop and U-Treasure Concept Stores in Ikebukuro and Shinsaibashi.

“Daiya no A” is based on the baseball manga by Yuji Terajima, serialized in Weekly Shonen Magazine. The story follows protagonist Eijun Sawamura as he enters the prestigious Seido High School baseball team and aims for the national high school baseball championship together with Kazuya Miyuki, Furuya Satoru, and Haruichi Kominato.

The TV anime aired its first season in 2013 and second season in 2015. A new series, “Daiya no A actII,” began in 2019, and its second season—the first in six years—is currently airing.

The newly released ring features a diamond symbolizing the “unbreakable spirit” reflected in the work’s title. Inside, you can engrave the name of your favorite player from a selection of 12 characters. On the front, a diamond-shaped motif is accented with blue resin reminiscent of Seido High School. The ring comes in a box featuring the logo.

The price is 19,800 yen for silver and 165,000 yen for platinum. Orders are accepted until Wednesday, June 10, 2026, so interested fans should not miss the deadline.
