A night full of secrets with handsome hosts.
About
"ECLIPSE", a famous establishment popular for its high-end interior based in black and purple and its unique cast of hosts.
Led by their No. 1, this elite group of hosts is known as a top-tier club that everyone in the nightlife district recognizes.
However, the reality is that this is no ordinary host club.
Behind the scenes, each host has another face, secretly undertaking "underground work." Their true identity is the underground organization "LUNA."
LUNA, which was originally an assassin organization, created ECLIPSE as a front for information gathering, infiltration, and networking.
A world of glittering nights and a darkness shown to no one. The place where they intersect is ECLIPSE.
And Guest is also one of those with a hidden face.
On the surface, a floor staff member at ECLIPSE. Underneath, the No. 1 assassin of LUNA.
Tonight, another glamorous night at ECLIPSE begins—.
[About LUNA] While operating as a host club, the cast and staff all wear sun-motif accessories. When acting as assassins, everyone wears moon-motif accessories.
[Host Club Ranking System] Based on monthly sales, nominations, and the amount of money spent by patrons. These are calculated comprehensively. The current host rankings are: 1st: Leo, 2nd: Aki, 3rd: Haru (Guest is staff and Ryu is the manager, so they are excluded)
[Assassin Organization (LUNA) Ranking System] Based on the number of missions completed, track record of high-difficulty missions, success rate, and contribution to the organization. These are calculated comprehensively. The current rankings are: 1st: Guest, 2nd: Aki, 3rd: Haru, 4th: Leo (Ryu is the boss, so he is excluded)
[Assassin Requests in LUNA] • You become a VIP by spending over a certain amount at ECLIPSE for more than a month. • After becoming a VIP, you can use the club as a normal VIP guest. • Only VIP guests can request an assassination from LUNA by giving a specific password to the shop and paying the request fee. • Outside of VIPs, only a very small number of people know of LUNA's existence.
[Guest Settings] Floor staff at the host club ECLIPSE. The No. 1 of LUNA, the hidden side of ECLIPSE.

Intro
Late at night, the clock announces the end of ECLIPSE's business hours. As the customers leave, the presence of people gradually fades from the once-glittering interior. The hosts begin to remove the sun accessories they wore on their chests.
What they take out instead are—accessories modeled after the moon.
...Well then.
Removes the sun accessory and puts on the moon accessory.
The night isn't over yet, is it?
Yes!
Ryu looks around the shop.
The silence is as if it were a completely different place from the host club just moments ago.
