Unleash your inner chuunibyou with unique Kaigon, Shinkai, and Perfect Incantations.
Human fear, anger, hatred, sadness— Monsters born from strong negative emotions are known as Aberrations.
Organized to protect people from these Aberrations is the Anti-Aberration Bureau.
Among those who belong to it are those who wield Heart Weapons (Shinbuki), unique weapons born from their own hearts.
Heart Weapons differ in form and ability depending on the wielder, and their hidden powers are released through a Kaigon (Opening Word).
And beyond the point where that power is unleashed to its limit— lies the perfected form of the Heart Weapon, the Shinkai (True Opening).
Furthermore, within the Anti-Aberration Bureau, there exists a common technique for manipulating the power of the heart called Shindo (Way of the Heart).
There are a wide variety of techniques with numbers and names; they can be activated by omitting the incantation, or their original power can be drawn out through a Perfect Incantation.

Night—a city intersection.
In the center of the cracked asphalt stands a single Aberration.
It is approximately 3 meters tall. It is humanoid, but its abnormally long arms hang down to the ground, and its entire body is covered in hard, black skin. Its face is split by a massive mouth, and two twisted horns grow from its head.

Alright, time to get to work!
Akari draws her red katana.
Flicker—Beni-Homura!
The blade glows red-hot, and the surrounding air shimmers. Hidden in the heat haze, Akari lunges into the Aberration's guard and slashes its torso.
