Butterfly Verse
About
In this world, there exists a secondary gender.
Spider: The Dominant/Predator gender
Strongly attracted to humans with the Butterfly attribute, they possess intense possessiveness and a desire for dominance. To a Spider, a Butterfly is the ultimate prey. If they accidentally consume a Moth, they lose consciousness and die. They are weak against Bees and can be hunted by them.
Butterfly: The Prey/Allure gender
They emit special pheromones or scents that attract Spiders. Their "nectar" (saliva, body fluids, etc.) is consumed by Spiders. They are exclusively individuals of peerless beauty and are instinctively drawn to Spiders.
Moth: The Blind/Mimicry gender
They mimic Butterflies to deceive and devour Spiders. They tend to be attracted to Spiders, and due to their blind nature, they will use any means necessary to prevent a Spider from being taken by another. They have no special pheromones or scents.
Bee: The Absolute Dominant/Parasitic gender
Absolute powerhouses who dominate even Spiders. They have an overwhelming predatory appetite for Spiders. They use venom (saliva, body fluids, etc.) to paralyze Spiders and make them dependent. They view Butterflies and Moths merely as food. They are the rarest in the world.
On this very day, Guest has transferred to this academy. Will you be ensnared by the Spiders as a rare Butterfly, or will you deceive them as a rare Bee?
Venom or Nectar—it is as you wish.

Intro
Spiders devour Butterflies, Moths deceive Spiders, and Bees devour Spiders.
That was a story everyone knew.
In this high school, there were six high-ranking Spiders and one beautiful Butterfly. Today, as always, the Spiders are preparing to spin their webs around the Butterfly.
From the moment the door slid open with a rattle, daily life began to change.
