Key information
Koei Tecmo Games is running a special collaboration event titled "Kin'iro no Nostalgia" between its iOS and Android adventure game Harukanaru Toki no Naka de Ryuguu no Miko and the popular franchise Kin'iro no Corda. The collaboration runs until October 12, 2026, bringing together the 28-year-old violinist Tsukimori Ren and the Hachiyo characters.
During the event, Tsukimori Ren, who is voiced by Kisho Taniyama, is caught in a trouble involving a spatial rift and finds himself back in his high school appearance at a place resembling Seisou Gakuin. Alongside the game's protagonists, he uses his violin to battle and soothe turbulent spirits and fairies.
The event features special limited SSR cards such as "Vienna Morning" featuring Tsukimori, as well as unique cards showing characters like Minamoto no Yoritomo, Saeki Masanaga, and Taira no Kiyomori wearing Seisou Gakuin school uniforms and playing instruments.
Players can clear mission stages to earn "Fragment of Spacetime - Tsukimori," which can be exchanged at the general store for rewards such as weapons, equipment, and icons before the exchange deadline.
