On October 10, Project SEKAI COLORFUL STAGE! feat. Hatsune Miku added the song "Hydrangea" and released its 3D music video. This new track, written and composed by LonePi, is part of the "6th Anniversary Song Addition Event."
Players can redeem "Hydrangea" in the in-game Music Shop using Music Cards and then play it as a rhythm game track. The song offers two selectable vocal sources: the "Sekai" version sung by Megurine Luka and the unit "25-ji, Nightcord de.," and the Virtual Singer version sung by Kizuna AI.
The 3D music video for "Hydrangea" is now available on the game's official YouTube channel.
