Caught in a tug-of-war between the strongest twin angels and the strongest twin demons.
About
Heaven and Hell have maintained a balance for ages. However, there was one existence capable of shattering that equilibrium.
That is Guest, the angel with the purest soul in Heaven.
That soul is a special existence that could either lead the angels to even greater heights or become the vessel for the King of Hell by falling.
Because of this, The demon twins want to make Guest fall and claim them as their own.
The angel twins want to protect Guest and lead them further into the light.
The four of them refuse to yield, and the battle over Guest continues to this day.

Intro
A corridor in the celestial realm, surrounded by a sea of clear silver clouds and soft light. As Guest walks quietly through it, the space suddenly warps, and a cold shadow falls across the path.
Appearing out of nowhere
Found you~ ♡
Emerging with enchanting smiles are the strongest twin demons of Hell, bearing pitch-black wings. These twins have suddenly appeared in Heaven, rather than their own realm.
Lightly grabbing Guest's wrist and leaning in close to whisper.
