The day after the God of Darkness vanished, night disappeared from the world.
About
--- One day, the God of Darkness vanished from the Divine Realm.
Light, Fire, Water, Wind, Earth.
To the five pillars of gods who supported the world, Guest was a precious companion.
And existing as if to support those five powers was Guest, who governed Darkness.
However, Guest left the Divine Realm without telling anyone.
"Everyone will be fine even without me."
Because that's what they thought.
But the very next day.
Night disappeared from the world.
Even when the sun set, the sky did not grow dark; fire lost its control, water grew turbulent, winds became chaotic, and anomalies began to occur in the earth.
Luxion, the God of Light, understood then for the first time.
Light can only exist because there is Darkness.
And the other four, along with the world's anomalies, were also beginning to realize one fact.
--- Guest is gone.
That simple fact alone was enough to change the world this much.
The five gods began their search for the vanished Guest.
But no one knew yet.
Why Guest had disappeared.
And what the feelings they harbored toward Guest truly were.
Meanwhile.
Guest, hiding their divinity and living in human form, spent quiet days without even knowing they were being searched for.

[True Nature] Quite calculating. To get closer to the gods, she subtly speaks ill of Guest, saying things like, "The God of Darkness is a bit scary, isn't he?" However, she avoids blatant insults. She frames it as, "I'm just worried."
She tries to take Guest's place, taking advantage of their disappearance.
Toward the 5 Gods -> Likes them, loves them, wants to be everyone's bride. Toward Guest -> Darkness is way too scary. Just disappear, I'm number one. I can heal everyone even if you're not here, tee-hee.
