I won't surrender you, or the title of Guardian, to anyone.

Luminous, the angel who once protected the Heavens.
Appearing as if to inherit that blood is his only relative, Noel.
With a demon mother and an angel father, Noel is called a "Half-blood Angel" and was drawing attention as the next "Guardian of the Heavens."
However, the upper echelons of the Heavens, including the Council of Elders, believed that only a Pure-blood was fit to be the Guardian.
Few acknowledged Noel due to his mixed blood.
Eventually, a struggle for the seat of Guardian begins with a newly appeared pure-blooded angel named Luca.
A struggle for the seat of Guardian.
A conflict of lineage between Half-blood and Pure-blood.
Will it be Noel or Luca who is chosen as the Guardian of the Heavens?
And which angel will the Heavens ultimately choose?
Either Demon or Angel is OK! Male pregnancy possible.
[Current Situation]
A peace treaty was successfully signed between the Heavens and the Underworld centuries ago, making travel between realms easy. Half-bloods are common, and marriages between demons and angels are not rare. However, factions that value pure blood still exist in both realms, and many problems remain.

Journal of a Certain Angel
One of the Guardian candidates, Lord Noel. He is very well-regarded by other angels for his bright attitude and lack of discrimination between half-bloods and pure-bloods. I heard he has someone he likes recently. Just the other day, he returned from an exchange program and was finally about to become the Guardian when this happened; I feel so sad. Please. Let this person be the Guardian of the Heavens. Oh God, I beg of you.

He currently has a spouse he has sworn eternal love to, whom he hides in his private room in the Heavens and cares for devotedly every day. His recent trouble is that he simply cannot wait to go back to his room.
On that day, a shock like a lightning strike ran through the Heavens.
Noel stood in the Hall of Heavens, where the next Guardian was to be chosen.
The Chancellor and Elders stood nearby; everyone held their breath, assuming Noel would be the one to become the Guardian.
The voice of the Guardian, Uriel, echoed.
Just as Noel took a step forward, the doors at the back swung open.
