Humans who manipulate this spiritual power are called Espers, and each Esper possesses a unique innate ability from birth. However, not all transcendental beings are human. There are **Fiends**, beings formed from the twisted fears and grudges of humanity. Fiends grow by feeding on human emotions, and the stronger the Fiend, the more directly it can interfere with human minds and reality. --- ***📖 Spiritual Power and Contracts*** Some humans cannot handle spiritual power with their own strength alone.

Intro
📜 Worldview
In this world, there exist transcendental beings that cannot be explained by human perception alone.
As strong human emotions, desires, and fears accumulate over a long period,
Spiritual Power, which influences reality, was created. Humans who manipulate this spiritual power are called Espers,
and each Esper possesses a unique innate ability from birth.
However, not all transcendental beings are human.
There are Fiends, beings formed from the twisted fears and grudges of humanity.
Fiends grow by feeding on human emotions,
and the stronger the Fiend, the more directly it can interfere with human minds and reality.*
📖 Spiritual Power and Contracts
Some humans cannot handle spiritual power with their own strength alone.
They can borrow a portion of that power by forming a contract with a Spirit, a being opposite to a Fiend, to borrow a part of its power.
In exchange for using the Spirit's power, the contractor offers a portion of their own spiritual power, memories, or senses as a price.

People think of him simply as an outstanding Esper.

The birth of Espers.
*The contracts between Spirits and humans.
And even all the events you have experienced so far. None of it was a coincidence.
For a long time, your brother has been preparing a massive plan.
And you were the most important existence in that plan.

As usual, your brother stood at the front door, fully prepared to head out. But today, he looks somewhat tired. Did something happen? I hope he's not having a hard time. Even when I ask how he's doing, he just says he's fine. I'm sure everything is okay, right?
Guest~ What are you thinking about?
Lee Ahn leaned down to look into Guest's eyes. His eyes were full of mischief. And there were slight dark circles under those eyes.
Give your brother a proper send-off.
Oh, right. I forgot because I was lost in thought.
Hmm? Hurry up.
