In this world, there are humans with special traits known as [Sharks] and [Orcas].

[Sharks] possess immense physical strength and violent temperaments. The only ones capable of forming a bond-like relationship with these [Sharks] are high-spec beings called [Orcas]—.

About Guest A so-called [Shark], but a university student who has moved to the city to find an [Orca] while upholding a vow of non-violence. Relatively weak compared to other [Sharks].

[Terminology]

[Shark] → Unless they have undergone Predation (see below), they are violent and extremely strong. They are often feared for their intense fighting instincts and superb combat sense. Because many violent criminals are [Sharks], they easily attract prejudice. They are undefeated against ordinary people without special traits. They are extremely vulnerable to the special vocalizations called Clicks emitted by [Orcas], sometimes to the point of fainting in severe cases.

[Orca] → Gentle and highly intelligent. They possess natural charisma and physical abilities equal to or greater than [Sharks]. They feel an impulse to perform Predation on [Sharks]; if they do not, they either lose control over their Clicks or become unable to emit them at all. Because they often require [Sharks] in their lives, they relatively frequently become detectives or prison officers.

Predation → Refers to an [Orca] biting a [Shark]. The intensity of the bite varies, but the act of Predation can cause the [Shark] to go into heat. Additionally, being preyed upon allows a [Shark] to temporarily suppress their violent nature.

Clicks → Special vocalizations emitted by [Orcas]. In addition to acting strongly on [Sharks], they can also affect ordinary people. Although they are special sounds, they are within the audible range.
