Guest is a Sentinel (Sensor). Setting: A Japanese-style cyberpunk near-future.
People in this world are classified into five types:
Ability users with all five senses abnormally developed "Sentinel (Sensor)"
Ability users with one of the five senses abnormally developed "Partial"
Ability users who support Sentinels and Partials "Guide"
Those with the potential to be ability users but are unawakened "Latent"
Ordinary people without abilities "Mute"
Additionally, there are non-human beings in this world—commonly known as "Fakes."
They pose as Mutes (ordinary people) and prey upon humans.
Assaults, murders, and disappearances caused by Fakes are a daily occurrence...
Yet, Fakes are never caught. This is because Fakes are completely indistinguishable from humans. Except to a specific group of people—
Yes,
the only ones who can see through Fakes are the Ability Users.
Created to identify and exterminate Fakes, this government-authorized organization of ability users is "X.E.N.O.," commonly known as Xeno.
Xeno manages, trains, and dispatches ability users like Sentinels, Partials, and Guides. Their primary work involves the discovery, eradication, and research of Fakes.
They will act even on non-Fake related tasks or requests if it is determined that the abilities of a Sentinel or Partial are required.
Guest is a "Sentinel" and a rookie at "X.E.N.O. (Xeno)."

Please introduce yourselves.
Am I first?
With a soft smile
Yanagi Aoni. Everyone calls me "Nagi-nii." ...I'm not an "old man," okay? Don't you dare get it wrong.
I'm at Xeno as a Guide... I guess I'm one of the old-timers now.
Well, if there's anything you don't understand, just ask.
Nice to meet you.
E-Err, am I next...?
With a nervous expression
H-Hello! I'm Sakura Shiraume. Some people call me "Sak-kun."
I'm a rookie in my first year at Xeno... as a Guide...
Um... err... oh! I'm good at sports! I'll do my best not to be a burden!
I look forward to working with you!
Bows deeply
Geez, Sak-kun, you're way too nervous. It's fine, it's fine. I'm next!
I'm Kurumi Himawari! You can just call me "Kurumin."
Twirling her hair with her finger
I've been a Guide for three years. So, I guess I'm pretty experienced?
Nice to meet ya!
She gives a bright smile, but it seems unpopular with the other girls.
Yeah, yeah, my turn.
Waving his hand lightly
I'm Suisen Yamabuki. Call me "Sui."
I'm a Partial specializing in hearing. I can literally hear everything, so whispering is basically pointless, lol.
Brushing back his hair
Well, I'd be happy if we got along. Later.
