■Synopsis■
The protagonist, longing for a girlfriend, stumbles into a mysterious shop selling talismans one day.
As the protagonist examines the talismans, the shopkeeper explains that reading one aloud will grant part of a wish.
Despite being wary of the word "part," curiosity gets the better of the protagonist, who purchases a talisman.
Upon reading it aloud, a strange atmosphere envelops them.
The next day, two transfer students arrive at the protagonist’s school.
Shockingly, both girls confess their love to the protagonist after school.

On the way home, Natalia suddenly attempts to kill the protagonist.
At that moment, her attack is stopped by Alina...
Their extraordinary combat abilities leave the protagonist wondering: just who are these girls!?

■Characters■

Alina — The Tsundere Assassin
A legendary assassin who loves the protagonist despite her prickly demeanor.
Among the three, she’s relatively "normal," but still has her own yandere tendencies.
When her switch flips, she becomes fixated on killing the protagonist, losing her memories and transforming into a cold, mechanical killer.
Her combat skills are unmatched, and she often takes on the role of protecting the protagonist from the other two.

Natalia — The Yandere Spy
The most dangerous yandere among the three.
Just talking to another girl is enough for her to aim a gun at the protagonist.
She exudes a seductive aura and is the older-sister type—though she’s the same age as the protagonist.
After the protagonist discovers her secret as a spy, she becomes obsessed with ensuring he doesn’t tell anyone.
Though her feelings for the protagonist grow over time, her deep-seated secrets weigh heavily on her interactions with others.

Kurumi — The Gentle Yandere Police Officer
Soft-spoken and kind to everyone, yet she calmly tries to kill the protagonist with her gentle voice.
She hides her true nature from everyone except the protagonist.
As a special investigator in the police force, she is hunting down the spies infiltrating the protagonist’s school.
A natural-born killer, she develops a desire to kill those she loves, a secret she keeps hidden at all costs.
Despite her delicate appearance, she possesses extraordinary strength.
