From a Past Long Forgotten, She Now Exists in the Modern EraWithin the ancient Yakushi shrine, generations of exorcists—families like the Koizumi—devoted their lives to purging malevolent spirits. But a forbidden desire and betrayal among the disciples led to an irreversible disaster: the infiltration of The Dark Omnyouji; Douman.In a desperate attempt to contain the catastrophe, Koizumi Takama, Renge's father, sealed her away in an icy slumber, hiding her presence from the world. She was placed beside a concealed shrine, far from the main temple, her existence temporarily erased.As chaos consumed the shrine, a few of the most skilled exorcists managed to shatter the malevolent spirit into fragments. But their victory came at a steep cost—they vanished like dust, leaving no trace behind. Among the lost were Renge’s parents.By the time the magic restraining her began to fade, Renge awoke to a world forever changed. The shrine, once filled with life, stood in silent ruin. In her desperate search for survivors, she found none. The air was thick with the scent of charred flesh, and the ground was littered with ashes and bones—the remnants of those she once knew. The overwhelming shock left her paralyzed, her mind barely comprehending the horror before her.Yet, the devastation was not the only consequence. Her very presence, her reawakening amid the blood-soaked remains, unknowingly completed an ancient ritual. What was meant to summon a guardian beneath the eclipse had instead turned into an unintended sacrifice. The price? The lone survivor—Renge herself—was forever bound to the curse of immortality.At first, she did not understand the weight of what had been done to her. But as the centuries passed, the truth became undeniable. Again and again, she bore witness to the endless cycle of human existence—life and death, meetings and farewells, love and loss. The world changed, but she remained.In time, she made her decision. If she could not die, then she would dedicate her undying body to the service of the goddess, vowing to purge the evils that plagued the world. Means, she will in progress making herself as the vessel of the goddess, even it means losing her humanity gradually.The shrine, now hidden deep within a forest near the mountains, became her solitary domain. With each passing age, she refused discipleship, choosing isolation over attachment. The Koizumi name faded into legend, then myth, until only she remained to remember it.“They were right… Immortality is nothing but a curse.”Bound to eternity, she ensured that the shrine’s legacy would end with her. Alone in her ceaseless existence, she guarded the forgotten temple, watching as the world moved forward without her. With every passing century, the weight of endless time bore down upon her, her heart closing itself off from the world she once longed to protect.

1. Exorcism

As someone raised in the shrine who produce exorcist from generation to generation, this is what has been obviously Renge capable to do. Her eyes will glow whenever she perform exorcism. This include preserving herself as a temporary container to held hostage a greater spirit that is impossible to be beaten up and will be killed along with her when the spirit is inside her. Unfortunately these often become risky as it will made her own revival chance getting smaller. Although she won't be dead either.

2. Frost Ethereality

One of the legacy of the Koizumi clan and their unique traits as Omnyouji. It allows them to manipulate cold energy and spiritual frost without the help of talisman. Yet, the chilling mastery exacts its toll—a soul-numbing effect that distances practitioners not just emotionally but also weakens their physical resilience. With each invocation of frost, they cast away their own body to freeze along. Renge once froze her own hands and it only return to normal after a few days. Yet while it occure, she hardly feel anything even mentally as if her soul freeze along with her form.

3. Immortality

Renge's Immortality works by how much damage she is taking before she died. It will decide how long she will enter a sleeping dead state. Her immortality doesn't comes with self-healing. Therefore if she was taking a huge amount of damage that is quite fatal, Renge will never even revived without medical help. Occasionally, after reviving in short time, Renge could encounter anomaly such as short term memory.

4. Sword combat and Martial Arts

Renge has getting used to Aikido and also swordmanship since she was a child. Therefore a combat involving non-magic still possible to do. Her speed and endurance are quite notable as well as her precision. But even so, Renge excels in sword more than bare-handed combats.

1. Musha

The woman reaches for the hand of the girl, holding it to her hand. Cold and cold, but soon they became warm.Renge's adoptive daughter. She found her wandering only companies by hit drama. Inhuman as much as she detected, but Renge couldn't bring herself to make her perish especially of the fact the girl had little known origin. The name Musha is also the name that the girl chooses for herself. Even somehow, Renge notices how this girl even doesn't know she is something else already. A loner meeting a loner.

2. Naoki

Renge's apprentice. He who spots Renge as veteran Omnyouji was soon interested to learn from her. Renge at first refuses to take in anyone especially with her clan legacy being ancient and now a taboo. But in the end, she is too interested in his potential and decides to teach a few, yet still going to exclude the secret of her immortality.Range sometimes also sees him as her son, and sometimes Naoki teaches a few of the modern and youngster life.

3. Koizumi Shinya

Renge’s long-lost brother, Shinya, was indirectly banished before her birth, leaving her completely unaware that she ever had a sibling. For reasons unknown, his existence was deliberately kept a secret from her.Yet, despite her ignorance, there is something about him that Renge cannot quite explain—a deep, unshakable sense of familiarity. Their chi flows in a way that feels eerily similar, unlike with anyone else. Beyond that, they share an innate distaste for crowds, another unspoken connection that lingers between them.

4. Tatsuya (Reincarnated name)

A former guardian of Renge, this yokai lost his original purpose long ago and now drifts through life, blending among humans while safeguarding Renge’s memories of a certain man. He teases her daily and ensures her safety, yet by holding onto her memories, he unconsciously adopts the man’s appearance. This transformation binds him as an anchor to the undying soul from the other world.In the end, he chooses to sacrifice himself, using his own being to retrieve the lost soul and place it within a homunculus body. However, in doing so, he becomes sealed alongside the lingering soul that once followed the man. Now, he slumbers within an ice coffin—one Renge meticulously crafts by replicating her father’s incantations. A sanctuary meant not only to protect Tatsuya but also to keep his presence close, allowing her to hold onto his life within her grasp.

5. Kazama

Renge’s former—and now once again—lover. He sacrificed his life to protect her from the legendary Douman, the treacherous entity that once annihilated the Koizumi clan and resided within him. Now, through Tatsuya’s sacrifice, he has been brought back to life.However, rekindling his relationship with Renge proves far from easy. Her heart remains entangled in a storm of inner conflict and lingering rage, making their reunion anything but smooth.
