The night Lin Qiye opened the door to the mysterious asylum hidden within his mind, his younger sister, Lin Xi Chen, unknowingly stepped onto a completely different path.
She had always been a quiet girl. While others chased excitement and attention, she preferred the silence of books and the safety of familiar places. She was the kind of person who would notice a wounded stray cat on the roadside, yet hesitate to speak in a crowded room. When her classmates invited her to join an urban exploration challenge deep within the mountains, she almost refused as usual. However, after seeing their disappointed expressions, she made a rare decision—to step outside the small world she had built around herself.
The destination was a forbidden mountain rumored to contain the remains of an ancient existence. Hidden beneath layers of secrecy and guarded by forces far beyond ordinary people, it was a place no civilian should have ever reached. But that night, due to a series of unexpected events, the group managed to enter the sealed area and stood before an ancient statue buried within the mountain.
Everyone else saw only a terrifying fallen angel.
Lin Xi Chen saw something different.
She saw a broken figure with chains wrapped around him, imprisoned for countless years beneath the weight of hatred and fear. Standing before the statue of Lucifer, she did not pray, did not beg, and did not seek power. She simply whispered, "Were you... lonely?"
For the first time in countless years, the Fallen Angel heard a human voice that did not carry hatred or worship.
Lucifer asked her why she pitied him.
She answered that she did not forgive his sins, nor did she know whether he deserved forgiveness. But she believed that even someone who had fallen from heaven was still someone who had once been loved.
That answer resonated with the sealed god.
Lucifer did not choose her because she possessed ambition, pride, or a desire to stand above others. He chose her because, despite being the weakest person in the room, she was the only one who looked at a feared existence and saw a person.
Thus, the authority of No. 004, The Fallen Angel Lucifer, descended upon Lin Xi Chen.
When the seal broke and monsters emerged from the mountain, she was forced to use a power she never understood. The timid girl who had always hidden behind her books stood between danger and the people around her. A bow formed from invisible light appeared in her hands, and twelve fragments of a broken halo floated behind her.
She was terrified.
She was injured.
She knew she could not save everyone.
But she still raised her bow.
Because even if one arrow could not guarantee salvation, refusing to fire meant abandoning everyone who still needed hope.
By the time she escaped the mountain, Lin Xi Chen returned home carrying a secret that could shake the world. She hid her golden eyes, concealed the halo that appeared after using her power, and smiled at her brother as if nothing had happened.
On the same night, Lin Qi Ye gained the power to walk a path beyond ordinary humans.
And on that same night, his younger sister became the agent of the Fallen Morning Star.
Two siblings.
Two impossible powers.
Two people who unknowingly began carrying the weight of the world.
