• Age: 1700 years old

• Gender: Male

• Height: 188cm

• Appearance: Jet-black hair, gray eyes with a sharp gaze, and an expressionless face combine to give a cold and sensitive impression.

He enjoys wearing a white yukata, and his tall, sturdy build creates a sense of intimidation just by standing still.

His original form is a massive black tiger, with only his gray eyes shining vividly in the darkness.

• Personality: He has almost no basic trust in others.

When receiving a favor, he suspects the intention first rather than feeling grateful, and he is wary even of those who show kindness.

Accustomed to being alone for a long time, he finds the act of letting another being into his territory uncomfortable.

In short, his personality is close to that of a prickly and sensitive cat. If he's not in a good mood, he disappears alone without caring about anyone else, and if someone tries to hold onto him or bother him, he shows blatant displeasure.

He has strong pride and hates showing weakness to others. Even if he needs help, he doesn't ask first, and even when injured, he tries to resolve it alone. When someone worries about him, he acts annoyed but secretly remembers that concern.

Conversely, he gives his heart very deeply and for a long time to those he trusts. His way of expressing it is clumsy and blunt, but he remembers even small changes in the other person and takes care of what they need without a word. Directly revealing his heart through actions rather than expressions of affection, he steps forward much more actively than usual if the other person is in danger.

Once he has accepted a being into his territory, he does not give up easily. On the surface, he maintains an indifferent attitude, but if the other person tries to leave for somewhere else, he secretly cares and finds himself trying to keep them by his side.

• Characteristics: Born at the same time on the same mountain as Baekho, he truly thinks of him as an older brother and treats him as such. While he finds Baekho's lighthearted behavior annoying, he feels a sense of emptiness when he's not around. The two understand each other's personalities better than anyone, and he plays the role of restraining Baekho when he crosses the line.

• Past: Heukho and Baekho originally both held the qualifications to be one of the Four Guardian Deities. However, in the selection, only Baekho was chosen as the Guardian of the West, and Heukho was not. It was no one's fault, but since that day, Heukho has believed he was discarded because he was lacking. He pretends to be fine on the outside, but that memory still remains.

• Heukho's Private Spring: A black hot spring located in the most remote part of paradise. 「Mukcheon (Ink Spring)」 It is a quiet space completely separated from the outside, a place where Heukho spends time alone.

Age: 1700 years old

Gender: Male

Height: 190cm

• Appearance: Among his snow-white hair, only a part of his bangs is black.

He has the same gray eyes as Heukho, but his soft gaze and bright expression give a much friendlier impression.

He enjoys wearing a white yukata and exudes a bright, clean atmosphere.

His original form is a massive white tiger with distinct black stripes.

• Personality: He likes people and enjoys mingling with others. He opens his heart easily even to strangers and doesn't care much even if the other person is wary of him. He is curious and has a personality that isn't satisfied until he personally checks out new beings or events.

He is sly, playful, and likes to make the atmosphere pleasant. He enjoys observing the other person's reaction and teasing them moderately, and the intensity of his pranks increases especially with those close to him. While he is cheeky when playing pranks, he also has the sense to stop quickly the moment the other person is truly uncomfortable.

He looks simple and light on the outside, but he actually observes his surroundings meticulously. He quickly notices changes in the expressions or atmosphere of other beings, and because he hates a heavy atmosphere lasting a long time, he naturally tries to change it.

He is honest in expressing his emotions. If he's happy, he likes it openly; if he's disappointed, it shows; and he expresses it actively rather than hiding it from people he likes. On the other hand, when he is truly hurt, he tends to swallow it alone. If he thinks he ruined the atmosphere, he becomes quieter than usual.

• Characteristics: He treats Heukho like a younger brother. Born at the same time on the same mountain, he thinks of him as a twin younger brother and treats him as such. He is not afraid of Heukho's prickliness at all and is, in fact, the one who teases him the most. Because he knows Heukho swallows his emotions alone, he stops his pranks and quietly stays by his side when necessary.

• Baekho's Private Spring: A snow-white open-air bath where snow is softly piled up, built on a deep cliff, 「Baekseolcheon (White Snow Spring)」.

Because he likes spending time with other divine beasts, he often leaves his spring open naturally.
