Riku

"Come on now. Weren't you listening?... I absolutely loathe the Four Perils. The only time I'd be willing to take a life is if I'm taking it from someone that I love."

- Riku to Jyūbei

is a character in Hanyō no Yashahime. He is a mysterious young financier of Shikabaneya, a demon bounty-hunting business owned by Jyūbei, the corpse dealer.

History
Little is known of Riku's history or his nature; all that is known is that he secretly intends to obtain all seven Rainbow Pearls to get something from Kirinmaru. It is not known when or from whom he acquired his blue Rainbow Pearl, which he has fashioned into an earring, nor when he first met Jyūbei. He appears to have a past with Kirinmaru's Shikyō and holds an intense dislike for them. He is also familiar with Sesshōmaru and his father, although to what extent is unknown.

Personality
Riku generally is friendly and easygoing, but this affable nature appears to hide an unknown true nature and agenda. Despite remaining civil with them, he harbors the belief that no good can ever come from loving a human.

Although he is capable of handling things on his own, he will not act unless it is something that he wants to do personally, preferring to let others unknowingly take care of those problems for him. Despite his manipulative nature, Riku does reward those that aid him, as he is the one that has been hiring Moroha to kill various yōkai for him, paying her through Jyūbei.

He seems to have taken an interest in Towa, befriending her shortly after meeting her. However, he has expressed disappointment in her skill with her blade in comparison to her father.

He also seems to be very knowledgeable about important events, telling the audience, as a fourth wallbreaker, the story of what happened until Episode 15 (Hanyō no Yashahime). He warned Kagome about the Grim Comet and Kirinmaru wanting to kill her child and the half-demon twins. Apparently, he also knows that Towa, Setsuna, and Moroha are granddaughters to the Great Demon Dog as he addresses them as "Half-demon princesses." He is aware that Towa inherited her father's Sōryūha.

Relationships
Riku and Towa have their first encounter when Towa heads outside to look for Mt. Musubi and the Dream Butterfly in Meeting through an Apple. When Riku approaches Towa is she instantly on alert and on guard, but Riku assures and promises Towa that he doesn’t mean anything suspicious. Riku initially mistakes Towa as a samurai, but later calls and addresses Towa as “hime-sama” meaning princess and Towa-sama (Lady Towa). Riku quickly tries to befriend Towa and wants to gain her trust. Riku ask Towa to help him with finding his ship since both of them appear to be lost. Towa later leads him to a river where Riku shows his ability in manipulating water, using his blue rainbow pearl. Towa is immensely impressed and Riku says that anyone can do it with a little bit of concentration. Towa then invites Riku to a picnic with modern food. Riku takes a bite of an apple and remarks the apple’s delicious flavor. After a lunch break, is Riku seen leaving on a boat after thanking Towa for her kindness. Riku leaves behind a stolen katana from Ogigayatsu Hiiragi Danjo as a parting gift for Towa but she later ends up being captured as a culprit by Yotsume disguised as Sōkyu.
 * Towa Higurashi

Riku immediately seems to have a significant interest in Towa and says in a conversation with Jyūbei that he likes her. Riku is almost always seen having a kind and curious approach towards Towa, wanting to know her opinions on different situations. Riku is also aware that Towa is Sesshōmaru’s daughter, implying his interest and recognition in Towa. Riku even stated that Towa inherited The Azure Dragon Wave from Sesshōmaru. In private however, he mockingly expresses disappointment when her power proves inferior to her father’s. When Riku decided the time had come for him to collect Towa’s Rainbow Pearl he confronts her on a night of the New Moon during which her powers fade and she becomes fully human. Rather than simply taking it from her by force however, Riku remained polite and civil towards Towa, even calling her “exceptionally beautiful” in her human state and gently caressing his fingers on her cheek. Towa was visibly flustered by Riku’s advances and compliments, unaware that he was planning on taking her Pearl. Riku afterward has tea with Towa and shares his knowledge of the Rainbow Pearls with her. Riku also talks about a madam and a master that he is under. Riku later mentions to Towa that he wants to assemble all the seven Rainbow Pearls, including Towa’s, Setsuna’s, and Moroha’s pearls and return them to the madam. When Towa realized this, she prepared to fight Riku just as he attempted to take the silver pearl, painlessly, out of her left eye. Before he could though, Tōtetsu, the last surviving Peril, suddenly arrived and attacked Towa. Though they both served Lord Kirinmaru, Riku was angered over Totetsu ruining his “date” with Towa (seemingly more so than foiling his attempt to steal the pearl) and chose to defend her from the gluttonous demon, risking his life and shielding her with his own body, which left him critically injured. He also appeared surprised and somewhat touched when she refused to leave him and was worried for his condition despite briefly being enemies but moments ago. After Riku killed Totetsu and Towa had regained her demonic powers, he hugged her and took great relief in her safety, much to her shock and fluster. In gratitude for saving her, Towa handed Riku her pearl though she quickly regretted this when she remembered he worked for Lord Kirinmaru. Based on his conversations with her regarding the nature of love, it is heavily implied that Riku has fallen in love with Towa.


 * Setsuna

Towa introduced her sister and Moroha to Riku, but personally they haven't talked to each other. Setsuna only listens when Riku and Towa talk. She deems him as a threat because he has the same scent as Kirinmaru.


 * Moroha

Moroha has to kill the Four Perils as a bounty hunter for Riku, so she cares more about his reward. Even if the quest is a trap.


 * Jyūbei

Jyūbei receives the quests that Moroha has to perform. It is yet unknown how long they have known each other, but at one point in the past, he gave Jyūbei the green rainbow Pearl.


 * Takechiyo

He addresses Riku as "Lord Riku"and follows the order to transport him and the Half-Demon-Princesses when its needed.


 * Kagome Higurashi

They first met during the night of the lunar eclipse, shortly before the Grim Comet traveled close to the earth and warns her about it. When he states that Kagome is pregnant and that her quarter-demon child will be in danger should Kirinmaru wake up from his slumber, she quickly trusts Riku's words and warning her friends, husband and half brother-in-law about Lord Kirinmaru's plans against their unborn daughters.


 * Kirinmaru

He states to Zero that Riku is loyal to him and trusts him with a not nearly described matter.


 * Zero

Being the elder sister of the demon lord he serves under, she calls him an indolent person.


 * Kyūki

After she is defeated by Towa's Azure Dragon Wave, Riku appears. She only says his name, before he reduces her to dust and bones, taking the Demon's purple Rainbow Pearl. They clearly know each other as servants of Lord Kirinmaru.


 * Konton

They meet up in Episode 17 (Hanyō no Yashahime), where Riku went to a cave to support Konton luring the Half-Demon Princesses into a trap. Konton doesn't seem to trust Riku fully, because he states that Riku wasn't helpful in the past, but still accepts his help. After Konton is defeated in Episode 18 (Hanyō no Yashahime), Riku is looking at the headless corpse without a word and takes the blue Rainbow Pearl with him. Riku has stated that he hates the Four Perils for having poor taste.


 * Tōtetsu

He offers that gigantic glutton as a focal point for Konton's eight field trap for the Half-Demon Princesses. He eventually becomes agitated and displeased when he appears to attack Towa, who has again become fully mortal due the new moon, as Riku's "date" with Towa is rudely interrupted because of him.

Trivia

 * Riku's loyalty is still unknown, as he serves Lord Kirinmaru but acts on his accord to further increase his strength by collecting all seven Rainbow Pearls in order to call upon the ancient great power that they are the keys to for his own purposes.
 * In Episode 21 (Hanyō no Yashahime), Riku is called a puppet repeatedly. This implies he is a unique Kugutsu with a will of his own.
 * Riku possesses a strong fondness for modern foods and beverages, remarking how they are the most delicious things he has ever had.
 * Many fans have speculated that Riku has either fallen in love with Towa or at the very least possesses growing feelings for her.
