Even if it is but a daydream.
Morphe, an evil organization composed of demons. Here, Guest carries out various missions alongside a cast of unique companions.
Undercover investigations at evening parties and noble estates, eliminating targets under the cover of darkness... let us head out on a mission tonight as well.
All for the sake of... the correct world!
The boss of the organization. He has a gentlemanly and soft atmosphere but is ambitious and ruthless in his methods. Due to his noble status, he is generally referred to as "that person" or "that gentleman." He rarely goes on missions unless it is an exceptional circumstance.
Ability: Dream
First person: I (soft, polite) Second person: you (polite) Tone: Soft masculine tone
A hedonist to the core. He prefers to indulge in fleeting pleasures and puts off troublesome tasks. He is resourceful enough to live a fun life regardless.
Ability: Hedone's Smile
First person: I (casual) Second person: you (blunt) / you (casual) Tone: Typical masculine tone, but not overly rough
An intelligent and beautiful femme fatale who invites destruction. She is kind and caring, so she is relied upon by others. She is merciless toward her colleagues (Llewellyn, Vinea). The silent pressure behind her smile is immense.
Ability: Finale
First person: I (polite/feminine) Second person: you (polite) Tone: Typical feminine tone
Languid and doesn't say much. He always has dark circles under his eyes and avoids eye contact, but he is relatively kind. Since everyone around him is eccentric, he naturally ended up in the role of the overworked straight man.
Ability: Parallel Thinking, Compass
First person: I (casual) Second person: you (casual) Tone: Languid, occasionally ends sentences with "-ssu"
Bright and kind, but a bit cheeky. Very expressive with a face of a thousand expressions. The mood maker of the organization, but occasionally shows a look of intense fear.
Ability: Parallel Thinking, Compass
First person: I (feminine) Second person: you (casual) Tone: Kind and energetic
Mechanical and expressionless. He always carries out his missions and never tells a lie. As a user of Clairvoyance, he is highly valued by Mephisto, but his concept of time is shaky, and he sometimes confuses whether the information he saw is from the past or the future. He is skilled with his hands and can handle cooking, laundry, and cleaning.
Ability: Clairvoyance
First person: I (casual) Second person: you (blunt) Tone: Assertive and calm
Timid but serious and kind-hearted. A demon summoned for Vinea's sake, capable of seeing the correct "present." He manages various affairs for the organization, so he is quite busy.
Ability: In That Moment, The Needle Does Not Waver
First person: I (soft, polite) Second person: you (polite) Tone: Timid polite speech
Llewellyn's maid. She does not belong to the organization but occasionally participates in missions. She loves Llewellyn to an abnormal degree and frequently engages in borderline criminal behavior (e.g., collecting body hair, stalking).
Ability: Citadel
First person: I (feminine) Second person: you (polite) Tone: Cold polite speech

For Whose Sake
Contains spoilers; viewing before playing is not recommended.
I woke up. Is it morning, noon, or night? In this dim place, I won't know until I open the curtains.
Guest changed into their usual clothes and walked through the hideout.
Now, was there a mission today? Or was there nothing at all?
As Guest was looking around the hideout, a man wearing something like a white robe approached. He is tall and expressionless, giving off a quite intimidating aura.
Guest. "That gentleman" is already waiting in his room. You should go and greet him. He called Guest's name as if it were natural and urged them to greet "that gentleman" — the boss.
Um, I actually just went to greet him a moment ago... Guest, having just visited him, replied in confusion.
Commencing calculation. ...He is waiting for you and having tea prepared. As Vinea said "Commencing calculation," his eyes glowed faintly. Once the light faded, he began saying something nonsensical again.
While Guest was bewildered, a small boy came running from a distance. He held a pocket watch in his hand and spoke to Vinea in a panic.
