[The blurb and character profiles may change. The only thing I'm sure of is that this is an upcoming interstellar novel.]
A transmigrator in a Sentinel-Guide world pretends to be a Guide.
Blurb:
A hypnotist arrives in another world with no money and no identity.
To survive, he falls back on his old profession, setting up a street stall as a doctor and providing psychological treatment to patients.
It seems that a lot of people in this world have psychological problems, so business is booming.
Patient A clutches a little wolf and says in anguish, "Without a Guide, I'm suffering so much! I hear so many voices every day! It's so loud!"
The hypnotist understands the second half of what he's saying and comforts him. "It's okay. They're just auditory hallucinations."
The hypnotist takes the little wolf and hypnotizes it.
Patient B brings a white tiger into the treatment room and begs, "Without mental guidance, my head hurts so much! Every day it hurts so badly I want to bang it against a wall!"
The hypnotist picks out the key words and reassures him. "It's okay. It'll be over soon."
The hypnotist strokes the white tiger and hypnotizes it.
Patient C brings a falcon and pleads, "Just one session of mental guidance is all I need. My falcon is shedding every day, and I'm about to lose it."
The hypnotist takes the falcon and hypnotizes it too.
Business is booming at the hypnotist's treatment room. Plenty of patients come to see him.
He doesn't know why, but all his patients bring their pets to be treated.
Then one day, he finds a badly injured kitten at his door.
The kitten is in terrible shape. It takes the hypnotist a great deal of effort to successfully hypnotize it and treat its injuries.
Fortunately, the kitten recovers quickly. Every day, it perches on the hypnotist's shoulder and massages him with its little paws, sweet and clingy.
Many days later, the kitten's original owner shows up.
The cat's owner is a person of great stature: the Federation's youngest general, and its only Dark Sentinel.
The general: I'm here to pick up my cat.
The hypnotist nods: Here you go.
The general: Our mental powers have merged, so we can get married now.
The hypnotist: ?
●
The Federation's capital city is home to a great many top-tier Sentinels.
But after the war, Guides grew increasingly scarce and were monopolized by the major powers.
Without long-term mental guidance from Guides, Sentinels gradually began to go mad.
Then one day, the Sentinels discovered a mysterious, unregistered Guide had appeared in the city!
The mysterious Guide was elusive and immensely powerful, able to control Sentinels' minds.
The mysterious Guide even defeated the Federation's strongest general and kept the general's spirit form by his side every day, tormenting it.
The general, after all, was the Federation's only Dark Sentinel, and his spirit form was a terrifying devourer capable of consuming anything.
But now the devourer was trapped beside the mysterious Guide and forced to get a massage every day!
What a vicious Guide! What terrifying powers of mental control!
