≪Introduction≫
Roselia takes on a new frontier with the release of their 18th single!

Their latest single, "Steadfast Spirits," was written specifically for the storyline of the smartphone game BanG Dream! Girls Band Party.
The song embodies Roselia's unwavering faith in the face of doubt and conflict. Opening with a powerful guitar riff, it unfolds dramatically, carving a path through thorny challenges one by one. This song is not only tied to the game's story, but also connects in a big way to Roselia's first solo Asia tour, kicking off in November 2025.

The single also includes the coupling track, "Shien," the third ending theme for the TV anime Cardfight!! Vanguard Divinez TV Series Deluxe Final Arc. With its gothic rock sound and powerful vocals, Roselia delivers a performance full of passion and nobility that's impossible to ignore.

The [w/ Blu-ray, Production Run Limited Edition] includes footage from Roselia: Sei stark, performed in June 2025 at Ariake Arena. Experience their fearless presence and let the image of the five members, united as one, stay with you.
Don't miss this album, which captures the full spirit and essence of Roselia!
