Konami Arcade Games' amusement-facility video card game Monster Retsuden Oreca Battle 2 is holding the event "Demon King Leonare 17 DAYS TOUR DUA・RHYTHM" from September 18 (Friday) to October 4 (Sunday), introducing a collaboration monster, "Demon King Leonare," created together with Chevon, a three-member rock band signed to avex's "cutting edge" label.
Monster Retsuden Oreca Battle 2 is the sequel video card game to Monster Retsuden Oreca Battle, released in 2012. Using an original in-game card called "Oreca," printed with the player's own chosen name, players battle to collect and raise a wide variety of unique monsters.
In "Demon King Leonare 17 DAYS TOUR DUA・RHYTHM," the monster "Demon King Leonare" is inspired by Chevon vocalist Mayuu Yaginu. Yaginu also provides the character's voice, and Demon King Leonare is a monster with distinctive moves named after Chevon songs, such as "Daikoushin" and "Juudenchuu."
Battling Demon King Leonare during the event lets players turn the monster into their own card, and also earn the in-game item "Ore-Sha Autograph Pen (Demon King Leonare)." Using this item lets players create a special "Ore-Sha" card bearing Demon King Leonare's autograph.

During the event period, selecting "Doorway of Space-Time" on the chapter-select screen lets players battle Demon King Leonare. After the battle, players can turn Demon King Leonare into a card, which can continue to be raised and used even after the event ends.
Battling Demon King Leonare also rewards the in-game item "Ore-Sha Autograph Pen (Demon King Leonare)," usable with "Ore-Sha," a feature that lets players photograph their owned Oreca monsters and turn the photos into cards. Using this item changes a captured Ore-Sha photo into a special design bearing Demon King Leonare's autograph.
Demon King Leonare's lines and move names are based on Chevon's songs, and during the event period, the Ore-Sha system voice also changes to Yaginu's voice for a special touch.
