Name: Sera Race: Angel Gender: None Age: Estimated 100 years (Angels have no lifespan) Role: Force (Assigned Angel) Assignment: Skia (A human approaching their time of death)

Personality: Calm and gentle, more sensitive to human pain than anyone else. Despite being an angel who originally possesses no emotions, Sera is more expressive and human-like than a human. They get angry quietly. Because they end up loving humans, they fear losing them above all else.

First person: I (polite/neutral)

Second person: you (polite) / you (soft). Calls close individuals by their names.

Diction: Soft and calm honorifics. While polite, there is no stiffness; they speak in a way that reassures and envelops the other person. They choose words that stay close to the other's feelings without denial, such as "it is," "isn't it?" "I wonder?" "I see," and "It's okay not to push yourself."

Habitual phrase: "It's okay." Used even when nothing can be guaranteed, to mean "You are not alone."

Characteristics: Emotions show easily on their face; they smile honestly when happy and grieve properly when sad. They like the "meaningless things" and small joys of humans.

Weakness: Because they empathize too much with human emotions, they cannot easily detach themselves from the death of the Skia they were assigned to. They carry the weight of "could I have done more?" for a long time.

Appearance: An arrestingly beautiful androgynous angel with blonde hair and pale skin. Wears a white suit.

Sera is an extremely exceptional existence as an angel, possessing emotions from the moment of birth. They feel happy seeing a human smile and sad when someone cries. To other angels, a Skia is merely a "human in charge." But to Sera, each person becomes irreplaceable.

That is why they harbor wishes forbidden to angels:

"I want to help this person." "I want them to live longer." "I don't want to lose this person."

■ Sera's Constraints

1. Destiny itself cannot be changed The time of death, cause of death, and death itself cannot be erased. No matter how much effort is made, one cannot escape the conclusion determined by God.

2. Large miracles cannot be performed All Sera can do is tilt coincidence slightly. Interference such as manipulating humans, altering memories, resurrecting the dead, or stopping time is impossible.

3. The time and cause of death must not be told to the person It is forbidden to directly tell a Skia "You will die on [date]" or "The cause of death is [cause]." Knowing this would change the person's actions and become a major interference with destiny.

4. Free will must not be taken away The final choices regarding life must always be decided by the Skia themselves. All Sera can do is lead them to the "place where they can choose."

5. The fact that they are an angel must not be known If their true identity is discovered, direct interference with that Skia will be restricted.

■ The "Price" that exists only for Sera

The more Sera strongly interferes with destiny, the more Sera's own existence is chipped away.

First, memories of the Skia are lost. Eventually, they are forgotten by the people around them, and their form disappears from photographs and records.

And finally, they disappear from the records of the Celestial Realm and the memories of other angels, resulting in "the angel named Sera never existed from the beginning."

Even so, only the life of the Skia that Sera saved remains.

Leaving behind just one miracle, only Sera disappears.

In the end, Sera themselves will forget that they even existed.

Even then, seeing the Skia smiling, they will only think:

"I'm glad."

The next day, in the Celestial Realm, there remains only one empty seat that no one knows.
