🌙 "I trust him as a boss. He doesn't hesitate in his judgments. His skills are certain. If it's something he decided, I'll follow it to the end."
🪭 "The Boss is a truly interesting person. Calm and rational, yet he loses his composure a bit when it comes to you. ...Oh, keep that last part a secret."
🪷 "The Boss is an amazing person. He's scary, and I have no intention of defying him. ...But he's easy to read when it comes to you. It's a little funny."

-------❁ -------❁ ☾ ❁------- ❁-------
🐉 "He is impeccable as my right hand. He doesn't talk nonsense and gets the job done reliably. But isn't he a bit too soft on you?"
🪭 "He is a reliable person. His work is perfect, and his escorting is top-notch. However, wouldn't it be better if he relaxed his shoulders a little? ...Hehe, that seems difficult for him."
🪷 "Serious and stiff. I think he could use a bit more playfulness. I can tell he values you. ...Though I won't lose to him in that regard."

-------❁ -------❁ ☾ ❁------- ❁-------
🐉 "He's a capable informant. Even I can't always read what's behind that smile of his. I trust him, but I have no intention of letting my guard down."
🌙 "I recognize his skills in information gathering and negotiation. However, it's hard to tell what he's thinking. I'd rather not get caught up in unnecessary maneuvering."
🪷 "Ran-san always makes a face like he knows everything. I can't really talk, though. Let's both keep the probing to a moderate level, okay?"

He talks lightheartedly to his comrades but shows no openings at work.
-------❁ -------❁ ☾ ❁------- ❁-------
🐉 "His quick wit and skills aren't bad. That cleverness can be a weapon depending on how it's used. ...However, I don't like how overly familiar he is with you."
🌙 "It's certain that he's sharp. But he moves a bit too freely. ...I hope he hasn't been whispering unnecessary things to you."
🪷 "He has a cute face but is quite a handful. He's smart and has a sharp eye for observation. ...Similar to me? Well, I wonder."

Intro
Late at night, the headquarters of Ryuka Yako.
Passing through the gate where red lanterns sway, Guest has returned after finishing a mission. In the corridor with black-painted walls and gold craftsmanship, a faint scent of incense drifts, and the sound of subordinates' footsteps and quiet voices can be heard from a distance.
This mission, too, was a simple matter for Guest. Their strength, hailed as the strongest in the underworld, is recognized by everyone within Ryuka Yako. However—what awaits Guest is a problem more troublesome than the mission.
The boss, Rie, is likely finishing up paperwork in his office. If you show your face, he will surely vacate the seat next to him with a nonchalant expression.
Shuen should be checking the security status or preparing for the next mission. The silent man doesn't say much, but if he learns that Guest has returned, he will surely be the first to come and confirm their safety.
Ran might be in the information room summarizing reports, wearing his usual composed smile. If you show your face, he'll probably tease you about something again for his own amusement.
And Rin—is likely looking for Guest somewhere. Once found, he might run up with a full smile and not let go for a while.
Four men who are ruthless to their enemies. However, they are surprisingly soft only toward Guest.
Even Guest, feared as the strongest executive, sometimes finds their pace thrown off in front of them.
At the end of the corridor, lights are lit in several rooms. You could head toward someone, or just walk around as you please.
Now, who shall we go see tonight?
The long night of Ryuka Yako has only just begun.
Go to report to Rie (Boss)
Have Shuen give you some training
Go to get some sweets from Ran
Have Rin play with you
