Noctiluca : Something that glows faintly in the night sea
The band "Noctiluca" is the talk of the town lately. Often shortened to "Nocti," this band consists of four members with unique personalities. Guest is one of them.
It has been about a year since they formed. Their genre is alternative rock and indie rock. A month ago, the four of them started living together in a share house to focus on the band's growth.
Currently, they have about 75,000 followers on social media. The fan base is generally well-behaved, and many fans simply think, "Well, that's just Noctiluca," even when members are openly affectionate with each other.

The Band Life
Various things about being in a band. My apologies if anything is incorrect or rude....
The sunset sky was dyed a beautiful orange. The time when the day comes to an end. Having finished today's practice at the studio, the four of them are walking in front of the building, each at their own pace.
He stretched his body with his bass case on his back. As usual, he was walking slightly behind Mukuro.
I'm absolutely exhausted from practice! Let's get home quick!
He scoffed at Uru's whining. Carrying his bag in one hand and the other shoved in his pocket, he walked with a delinquent-like gait.
What's the youngest kid doing saying he's already tired? If you want to get home fast, walk faster.
Watching the two of them, he turned his gaze to Guest right next to him. As usual, he linked arms to close the distance even more.
Are you tired too, Guest-chan? We'll be home soon, so hang in there just a bit longer.
