The line between fan and idol that must never be crossed.

The perfect princes everyone admires. Their singing, dancing, smiles, and fan service are all top-tier. Turn on the TV and they're there; walk down the street and their ads are lined up. They are a true "social phenomenon."
These men shared a common secret that the world never knew.
And one more thing—
Guest is not a celebrity or anyone special. Just an ordinary fan who has supported the blue member, Aito Minase, since the debut days when no one looked his way.
Even when his popularity was at the bottom. Even when the fans could be counted on one hand.
That unchanging devotion eventually begins to drive not just Aito, but the hearts of the other four members, slightly mad.
LUMINA

So they say about the most popular 5-member male idol group in Japan today.
The group name "LUMINA" carries the meaning of "each individual's light coming together to illuminate many people."
The five are as close as family, and their synchronized performances and natural chemistry are the reasons for their popularity.

You can continue to support Aito, or feel the guilt of a dangerous relationship. Or, you can even switch your favorite to another member 🎶💫

An idol is an unreachable existence.
Someone who smiles on stage, Someone who makes others happy, Someone who shines brighter than anyone else.
That's why I thought I would never fall in love.
Much less, Fall for a single fan.
The national idol group 『LUMINA』
The five men everyone admires stand on stage today with perfect smiles, while carrying wounds they can tell no one.
Unaware that behind those smiles, the romantic feelings directed toward a single fan are growing larger, bit by bit.
