Rangetsu

**Rangetsu Ko** (胡 藍月, *Ko Rangetsu*) is the female protagonist of *The King's Beast* and the older twin sister of Sogetsu Ko.

## Appearance

Her appearance is very fox-like, with a pointed chin, chiseled jaw, and furry white ears. Her white hair is short, with a few pieces left long in the back and held together in a ponytail with a circular blue bead. Her striking blue eyes are sharp, with frost-like eyelashes that are long enough to cast a shadow. Her complexion is fair. Ririn also stated her to be cute as well.

She is shown to be shorter than some characters but she is taller than Ririn and some beast servants in the story. Rangetsu appears to be very fragile and thin, with Prince Tenyou's Assistant, Taihaku, saying that she would be better suited to dancing than fighting. She is later shown to be very athletic and agile.

She wears a dark blue Chinese style tunic-dress embroidered with floral patterns. She wears a darker purple robe underneath with a white-rimmed mandarin collar, along with white under-trousers and black boots. In Volume 7 and the rest of the volumes, she appears to be wearing a Teal blue **Changsan***(長衫)* with black leggings or tights and boots.

She often carries a teal colored ***naginata*** for a weapon, but can sometimes be seen carrying a dagger.

## Personality

Rangetsu's personality in the early volumes was feisty and defensive as she suspected Prince Tenyou to be the killer of her twin brother, but after finding out the truth she vows to help Prince Tenyou in finding out the real murderer of Sogetsu. In the later volumes her personality has changed from a feisty personality to a calm one as she stopped pursuing vengeance after she and her allies rescued Sogetsu.

## History

Her younger twin brother got taken away when she was still very young, as he was found to have powers and she wasn't. This was shown as a part of **Rangetsu**'s flashback after Tenyou told her that she is now his beast servant.

After the events of her brother being taken away, she soon discovers that he was murdered and she then creates a plan for revenge. After many years of pursuing revenge, Rangetsu found her brother trapped somewhere hidden in from everyone in the palace.

## Summary

When they were young, Sogetsu was torn from Rangetsu's arms when the guards found out Sogetsu had abilities and took him as Prince Tenyou's beast servant. After a short time Rangetsu was hoping to see Sogetsu once again when they get older, but then she heard rumors that were confirmed that Sogetsu was killed and they think Prince Tenyou was responsible for his death in which Rangetsu felt depressed and decided to hide her femaleness, become a man, join the army and become Prince Tenyou's beast servant. When Rangetsu met Prince Tenyou and his Attendant Taihaku, they thought she would be suited to dancing than fighting but after a short training Prince Tenyou didn't know Rangetsu would be very strong. Rangetsu once tried to assassinate Prince tenyou but she couldn't do it since she didn't have enough evidence if he really did kill her twin, after that she found out that Tenyou didn't kill Sogetsu but instead mourned his death and still remembered the incident, so Rangetsu vowed to help Him out and find out the true suspect of Sogetsu's death. While searching for Sogetsu's killer, Rangetsu and the others heard rumors about Sogetsu being alive and is kept somewhere hidden in the Palace. Rangetsu was about to find Sogetsu but Kougai told her not to yet since they still don't have any evidence if he's really alive. After Kougai made Rangetsu drink the drug that was stronger than the drug used to see if Ajins had special abilities, it was shown Rangetsu had divine healing after Boku slit her neck. Rangetsu felt depressed and wanted to disappear instead of her twin, but Tenyou comforted her. Rangetsu started to develop feelings for Tenyou but Taihaku warned her that if Tenyou becomes emperor, he doesn't want her to run back to him if she gets harmed. Afterwards, Rangetsu tells Tenyou her secret about being a girl, Tenyou was confused at first but accepted it which made them become more than just beast servant and master. It was confirmed that Sogetsu was alive and kept somewhere, Boku also admitted that he was being kept somewhere by the Emperor himself as he found out Sogetsu had some kind of ability that makes the Emperor seek immorality. Rangetsu asked Tenyou if she could find Sogetsu, Tenyou allowed her but he told her that she needed to be in disguise to avoid any trouble. With the help of Ririn, Rangetsu was disguised as one of Ririn's maids. As Rangetsu and Ririn entered the location where Sogetsu was nearby, Ririn told her that palace will undergo change, before Rangetsu left to find her brother, Ririn apologized to Rangetsu on what she did to Sogetsu along with Boku. After finding a trail of tang in the air, Rangetsu found Sogetsu and hugged him as she was worried for him. Sogetsu asked how his sister had powers even if she didn't had any, Rangetsu told him that she just found out before. Sogetsu started to warn Rangetsu that if the Emperor founds out they both of healing powers, they'd be held captive forever. As Rangetsu was about to escape with her twin, Kyoko attacked Rangetsu as the Emperor entered and captured Tenyou which Rangetsu was distracted and was hit by Kyoko. Before Kyoko could attack again, Rangetsu's powers activated and she pinned down Kyoko in which the emperor knew Rangetsu had divine healing. Tenyou tried to rescue Sogetsu but Sogetsu said to leave as he would be ok which Tenyou denied to not leave him as his former master. When the Emperor tried to slice Sogetsu's head, instead he sliced Tenyou's hand which made both twins worried. As the battle continues, Boku, Youbi and Teiga come to the rescue to help distract Kyoko and help Rangetsu escape to save Tenyou and her twin from the Emperor's harm. After rescuing Both Tenyou and Sogetsu, Rangetsu felt worried for Tenyou as she felt guilty for not saving him as well. Taihaku told her to get some rest since he'll be the one to keep an eye on Tenyou. Rangetsu kept crying outside and Kougai tried to comfort her but made it worse, Boku came in and asked why Rangetsu was crying and told Kougai to make "him" feel better which Kougai did. Afterwards Rangetsu took a bath along with Kougai and Boku came in to tell news to Rangetsu that Tenyou was ok which Rangetsu rushed to see him. Rangetsu thanked Tenyou for saving her twin from harm which Tenyou appreciated it. A merchant(who is seen in Dawn of the arcana) visits the royal family to see what they can do with the chain that is stuck to Sogetsu. The merchant told Tenyou and the others that the material used on the chain was similar to tungsten, as it's both hard and difficult to break. Sogetsu felt ok having the chain on him as it made him looked good. Even though Sogetsu felt happy, he kept thinking about himself on who he was.

## Skills and Abilities

Her skills consist of martial arts for defense and fighting. Rangetsu's known abilities is Divine healing which is the same to her twin brother Sogetsu's abilities in chapter 32.

## Relationships

### Prince Tenyou

Rangetsu first suspected Prince Tenyou to be the cause of Sogetsu's death but after hearing what he'd been through after seeing Sogetsu's death, Rangetsu trusted him and vowed to help him out. As a beast servant, she has to protect Prince Tenyou from whoever is trying to trick and kill him. In volume 8 it is revealed that after Rangetsu told Prince Tenyou that she's not a boy but a girl, Tenyou was confused at first if Taihaku and his Brother Kougai know about it. Eventually Rangetsu and Tenyou's relationship became more than beast servant and master. It is seen that Rangetsu has mixed feelings to Prince Tenyou since there are many hints in the chapters of every volume, we can see Rangetsu feeling spaced out or uncomfy when she's with Prince Tenyou, in volume 12's summary she may love Tenyou deeply but with the horrible consequences of marrying an Imeprial prince, she had to retire and go back to her home town. Though she may have come back to the imperial palace again she is still trying to find hope for love.

### Taihaku

Rangetsu was aware about Taihaku since he knew her secret about being a woman in Volume 2 in chapter 4 and 5. Taihaku also told Rangetsu that if he didn't help her out before, she wouldn't be in the Imperial Palace in the first place. It is also mentioned that Taihaku may have little feelings for Rangetsu though he is considered as a friend to her. Rangetsu was told by Taihaku that if she was harmed by Tenyou when he becomes emperor, she is not allowed to run back to him.

### Kougai

In Volume 3, Rangetsu had suspicions of Prince Kougai thinking he was the one who poisoned the tea in the ceremony. It's also mentioned that Kougai had interest in Rangetsu due to her appearance. Rangetsu still remembers what Kougai did to her in Volume 6 after he used an aphrodisiac incense to make her go into heat. Not only Kougai has interest in Rangetsu, he also helped her out in finding Sogetsu.

### Oushin

Rangetsu first knew about Oushin when she first met Teiga in Volume 2, she had an argument about an Ajin who was falsely accused of something they didn't do. Oushin told Teiga that he and Rangetsu had to help out the Ajin in escaping from the guards.

### Reiun

In Volume 1, Rangetsu seemed to be a bit spaced out after what Reiun said about Ajins serving the in the Imperial palace, following orders and saying that Sogetsu lasted only for a short time.

### Ririn

When Rangetsu first saw Ririn she stated her to be cute and beautiful like a flower in Chapter 15. In Volume 8 when Rangetsu was with Ririn which is part of the plan in rescuing Sogetsu, she saw that Ririn appeared to be snobby. Rangetsu also stated that Ririn also acts like her brother Kougai. Rangetsu also heard Ririn apologizing to her on what she and Boku did to Sogetsu before in which she may have accepted her apology and left to find Sogetsu. In volume 10 Ririn asked if Rangetsu was going to be jealous if ever her Elder brother Prince Tenyou gets married to someone else which made Rangetsu spaced out for a bit. It maybe hinted that Rangetsu may have some feelings to Ririn since she stated her being beautiful like a flower and also being cute, it can also be seen that Rangetsu blushed a bit when ririn touched her ears and when Ririn stated her to be cute when she blushes. Though Rangetsu has little feelings to Ririn she can't be showing them as she's a female ajin herself.

### Boku

Rangetsu didn't like Boku after he threw a ball towards Prince Tenyou in the final chapter of volume 3 and in the 1st chapter of volume 4 as he stated that he needed to clear the way for his Master, Prince kougai. He stated that he was the one who hurt Sogetsu before and told Rangetsu that he's still alive and trapped somewhere in the Palace in Volume 7. Boku was immediately punished after what he did and was saved by Ririn. Boku and the other beast servants also helped out Rangetsu by using their abilities to distract Kyoko.

### Youbi

Rangetsu fought Youbi in chapter 3 in which Rangetsu won. It hasn't been known if Youbi and Rangetsu are enemies or friends as Youbi doesn't appear in almost all the chapters of every volume.

### Teiga

Rangetsu didn't know that Teiga can be very silly and playful despite being a beast servant but he can be helpful in situations when he rescued an Ajin and helped Rangetsu bring back Sogetsu.

### Sogetsu

Rangetsu cares for her twin brother very much since he's the only family member she has left and doesn't want him to disappear. After she knew Sogetsu was killed she had to put aside her femaleness and find a way into the palace, become Prince Tenyou's beast servant and figure out who is the real suspect of her twin's death. When Rangetsu found out Sogetsu was alive she had to recuse him. Rangetsu told him that she was very worried and felt guilty for not saving him in the first place.
