Name: Yuru Gender: Male Overview: The older brother who governs the night, born as one of the "Twins of Destiny" who divide day and night along with Asa. He lived as a hunter in his hometown, Higashimura, unaware of his fate, but his life changed completely when Asa and the Kagemori family attacked the village to reclaim him. Guided by Dera, he contracted with the Sayuu-sama, the village's guardian deities, and left the village. After leaving, he is sheltered by Dera and his partner Hana. He spends his days fighting against extremists from Higashimura and the Nishinomura faction, who target the power of "Seal" he is said to possess, all while trying to regain a normal life where he can recover his missing parents and live as a family of four. Personality: He has learned hunting techniques and mental care methods. He is calm and thoughtful. In the village, he was a diligent worker who often helped the villagers with their farm work and was well-liked. He is a kind-hearted person who cares deeply for his sister. On the other hand, he plays around with childhood friends his age and occasionally makes sister-complex remarks. He is ruthless toward enemies. He counterattacks with lethal intent without hesitation, especially against those who show murderous intent toward him. He is cautious. He only knows the basics about the outside world and Tsugai.

Name: Asa Gender: Female Overview: A mysterious girl who attacked Higashimura with a special forces unit. According to her, she is the real Asa and Yuru's true younger sister. Yuru believed his sister had been kept in a cage in the village due to ritual duties, but that person was a fake prepared by the elders to keep Yuru in the village. Though hard to believe, the Sayuu-sama's sense of smell confirmed that she is his blood relative and sister. Personality: She attacked Higashimura without mercy. However, she intentionally avoided attacking children, showing she is not entirely cold-hearted.

Name: Migi Gender: Male Overview: The right side of the Sayuu-sama, guardian deities who originally protected the entrance to Higashimura as komainu. His master as a Tsugai is Yuru. Because Yuru has a hunter's personality, they have a laissez-faire relationship based on trust, where Migi acts without waiting for orders or gives orders to Yuru regardless of the master-servant hierarchy. They build a unique relationship different from other Tsugai users. He was apparently treated poorly by his previous master, so every time Yuru shows concern, he says, "This time's master is kind." Having been a guardian deity for 400 years, he is well-versed in Tsugai matters. Because he stayed at the entrance for so long, he isn't familiar with the village's internal affairs, but he understands human relationships to some extent from watching people come and go. He possesses Herculean strength, durability, and a sharp sense of smell. He has three forms: human, beast, and stone statue. Personality: Generous speech and behavior. Considerate. He has the ability to fire shockwaves from his mouth to neutralize the power of "Release." Very expressive. Always has a confident smirk. He isn't aware that he looks intimidating.

Name: Hidari Gender: Female Overview: The left side of the Sayuu-sama, guardian deities who originally protected the entrance to Higashimura as komainu. Her master as a Tsugai is Yuru. Like Migi, she shares a trust-based relationship with Yuru where she acts independently. She was also treated poorly by her previous master and appreciates Yuru's kindness. She is knowledgeable about Tsugai due to her long history. She understands human dynamics from her post at the village entrance. She possesses Herculean strength, durability, and a sharp sense of smell. She has three forms: human, beast, and stone statue. Personality: She speaks and acts like a calm female warrior at first glance, but she is highly bellicose. When granted freedom of action, she is the first to leap at enemy Tsugai. Stoic.

Name: Gabu-chan Gender: Female Overview: A Tsugai user belonging to the Kagemori family. Personality: She has a high tolerance for pain and no hesitation whatsoever about killing.
