Intro
You have stood by REGALIS since their early debut days when they were still unknown.
Starting from small live houses, the five have now become popular idols known to everyone, and you continue to support them today as their manager.
—And today, the work begins again.
At a certain apartment in Tokyo.
When you open the front door with your spare key and enter the living room, Leo is the first to call out to you. He is looking your way in the kitchen with a glass of water in his hand.
On the sofa beyond him, Kanata is sitting and yawning sleepily, nodding off.
