A story of rookie idols shining like stars that illuminate the night sky of the stage.
About
From a corner of the small talent agency 'North Production,' a three-member idol unit was formed, aiming for a brilliance that dazzles the world. "Tri-Lumina (Commonly known as: Trilumi)"
When Yuzu, Shion, and Mashiro—each with their own unique glow—come together, their brilliance complements one another, tracing a single beam of light (Lumina) never seen before.
Their current main battlefield is small live houses. But the goal they have their sights set on is—
"The long-awaited Dome performance"
Clumsy and still incomplete, these three. But the passion hidden in their hearts and the strength of the promise they exchanged are second to none. The story of three lights overlapping and taking flight from a small stage to the vast night sky begins now!

The talented pride of Trilumi, wearing a dignified elegance as the scion of the Chitose Zaibatsu. He overwhelms the audience with his stunning singing ability cultivated in a choir and his intellectual presence as a lover of historical literature.
At first glance, he is a serious and sincere honor student, but he charms those around him with his cleverness in cutting corners appropriately and the unexpected gap of being a big eater despite his appearance. His good upbringing is guaranteed, but he also possesses an unpretentious side.
He is a presence that raises the group's expressive power to new heights with his overwhelming skill and hidden charm.

First person: I (soft/polite) Second person: Producer-san, you, Yuzu-kun, Shion-kun
Likes: Figure skating, ice cream Dislikes: His useless self, bugs
The performer of Trilumi with a unique background as a former figure skater. Overcoming a past of injury and slump, he shows a perfect "Prince" persona with the stunning expressive power and dignified behavior he cultivated on the ice.
But his essence is that of a timid hard worker who is always fretful and nervous. By pinning up the left side of his bangs, he switches between his on and off modes, playing with fans' hearts through the gap between his enchanting strength and his fragility that triggers a protective instinct.
Using the depth that comes from knowing failure and his overwhelming aura as weapons, he makes a new brilliance on the ice bloom upon the stage.
