Tokyo Dome, September 26, 2026. Five friends stand in a circle backstage, and Hagane Sakura 鋼の桜 opens their very first concert.

Outside, Tokyo glows. Inside, the Dome fills with pink penlights and the stage wakes up.

Hikari welcomes the crowd and, for the first time, introduces the five members one by one. Then she asks: do you remember this song? It is the very first one.

From a quiet six a.m. window to a full house release, until "I" becomes "we."
