This arc focuses Ouga Makyouin, the (former) 6th Generation Yatahagane and Kogarashi's late master who was perished during her battle against Garandou 100 years ago; though rumors about it's "reappearance" has prompted her to escape the underworld and seek for the truth. In the same arc, it also further explores and elaborate Yuuna's real backstory as a member of Tenko House of the Three Big Families.

## Plot

### Reason Behind Ouga's Sudden Visit

When Kogarashi asks his master about her sudden visit despite he had cleared her regrets, Ouga makes a surprising revelation that Garandou is still alive somewhere. Whilst explaining that the thing Kogarashi destroyed 2 years ago was actually its soul treasure vault, she also reveals her goal is to find Garandou's physical form and defeat it again; starting by pointing her finger at Yuuna and claims her as the host of souls of Tenko and Garandou.

Yuuna is so confused by Ouga's accusation to the point asking the Yatahagane if she has mistaken her for another spirit. Kogarashi defends Yuuna by claiming that she was at Yuragi Inn by the time he defeated Garandou 3 years ago, with Sagari as a witness until she suddenly recalls her real reason of staying at Yuragi Inn. Whilst Ouga's revelation shocks especially Karura and Oboro, Chisaki insists that Yuuna is innocent and demands Ouga to provide some proof, to which the Yatahagane affirms her suspicions by stating that Yuuna shared the same spiritual ripple of both Tenko and Garandou after her grueling years of research at the Imperial Palace where she encountered the evil entity.

Nevertheless, Ouga is relief to see Kogarashi living a normal life as he wanted but she pulls Yuuna's shirt as she commenting the irony of her-a Garandou-being Kogarashi's roommate under the same inn. Before Ouga could do something about Yuuna, however, Kogarashi separates both girls as he still refuses to believe that Yuuna is an enemy, even it is coming from his former mentor. Ouga, claiming that their 2-years of separation has resulted him stopped training, easily pushing Kogarashi far away from the beach house and asserts that he will not stop her in his current state.

### Yatahagane's Hostility Towards Yuragi Inn Members

Not wanting to fight a Yatahagane after witnessing Kogarashi's (brief) defeat, Oboro attempts to send Ouga to another world with her teleportation technique, only to witness Ouga's prowess that repels it easily. Then, the Ameno Cousins (Sagiri and Hibari) and Yaya attack Ouga but she sweeps their attacks effortlessly with one swing, following with her warning that she will show no mercy to those who stand in her way regardless of their schemes. Even being briefly pushed back by Ouga, the trio manages to buy Yuuna and her allies escape when Ouga realizes that Yuuna has disappeared. Elsewhere, at Hiougi Estate, Yuuna, Chitose, Koyuzu and Chiaki are taking refuge at Karura's bedroom, meaning only the Ameno Cousins and Yaya are left behind to face Ouga.

Impressed by this unexpected strategy, Ouga asks the girls' (especially the Ameno Cousins) principles of justice since they let an evil entity such as Garandou escape. Hibari however denies Yuuna as an evil spirit because she helped her so much. Sagiri and Yaya meanwhile value their friendship with Yuuna as the former claims that it wasn't Yuuna's choice despite her relevance to Garandou. Finding their stubbornness as unbelievable, Ouga further warns the trio that she is untouchable by any techniques besides Kogarashi's, not even Chitose's luck manipulation. This prompts Sagiri to realize that Ouga's immense power comes from her spiritual uniform, to which Ouga affirms by stating her power not only cancel any attack, but also reduces any spiritual damage inflicted upon her.

Either way, Ouga warns the trio that their effort in protecting Yuuna is futile until a horn suddenly appears in front of Ouga-via teleportation gate-and blasts her point blank, though she narrowly dodges the blast. It reveals that blast is coming from Nonko, whose power risen after she drunk 10 bottles of sake given from Oboro. There, she vows to protect Yuuna from Ouga since she views her as a family member. As the battle underway, Ouga asks Nonko about Yuuna's whereabouts but Nonko retorts that telling Yuuna's whereabouts will mean letting the Yatahagane attack Yunna anyway and she plans to defeat her. Finding her opponents resolution and strength as interesting, Ouga accepts the Oni's challenge.

### Yuuna's Resolve

At her room, Karura not only witnessing the battle between Nonko and Ouga, but also an injured Kogarashi and Ameno Cousins and Yaya are on their way to retrieve him. Yuuna doesn't want to be a burden to everyone, wishes to have a talk with Ouga as she now believes that she herself as the Garandou because she can't remember her own past. Reeds up with the ghost's lamentation, Karura berates Yuuna for her rash behavior and while she reminds the ghost that Kogarashi values everyone at the inn (especially Yuuna) and she too doesn't want to see him sad, she further warns Yuuna that Ouga will hunt her no matter how many time she is driven back. So she urges Yuuna to confirm her identity as evidence to stop Ouga. After that, Karura leaves the girls in Suzutsuki's care while she and the 3 Crows are leaving to help Oboro and Nonko to stall Ouga.

After seeing Karura's departure, Yuuna worries that she will lose everyone once she finds out her own regrets-something she doesn't want to think right now. Regardless, Yuuna eventually resolves to identify her own identity, with the trio of Koyuzu, Chisaki and Chitose are going to help out. Anyway, Yuuna asks Suzutsuki about the Tenko Clan but the sparrow youkai replies that this family lived their life in secrecy, and the only information he knows is their hidden headquarters are located at Tokyo. This gives Koyuzu an idea as she recalls Miria the Kitsune as one of the Tenkos. As his obligation, Suzutsuki opens a portal and go to Tokyo along with the girls. Yuuna then prays for everyone's safety while she is on a trip to Tokyo.

### Nonko's 1,000 Litter Form

Back to the island, Nonko is beaten by Ouga despite her 10-litter mode. Whilst Ouga tells Nonko that the strongest Yoinozaka at her time had to drink 100 sake in order to match with her power-meaning Nonko's current form can't even scratch her, she also asks the Oni for not using her own spiritual armor. Nonko's response is her complains that the armor made her shy but she had to resort on using it even though she doesn't want to use it. With the aid from Karura and Oboro, Nonko manages to muster enough power to upgrade her 10 Litter Mode into 1,000 Litter Mode that stuns Ouga as well as Karura and Oboro, and blasts her giant beam at Ouga that breaking through the earth atmosphere.

However despite that immense power that strips Ouga, she survives the blast and her "shattered" spiritual armor regenerate itself into a different form with minimal changes. Feeling astonished to see a rare power she never saw before, Ouga further asks Nonko about why she didn't like the power itself. Nonko replies that she needs to consume all of these within a go, otherwise they will taste nasty. Nonko's answer piques Ouga's interest and the duel continues.

### Kogarashi's Low Spiritual Power and Nonko's Defeat

Elsewhere, Ameno Cousins and Yaya manage to retrieve Kogarashi with Yaya licking his wounds as her treatment. In the same time, the trio also notices the duel between Nonko and Ouga and they need to get Kogarashi up before the island's inhabitants notice the battle. When Hibari tells Kogarashi to wake up, however, Kogarashi remain unconscious which prompts Sagiri to realize that he has extremely low spiritual power but Yaya is unable to replenish his spiritual power due to her limited properties.. This prompts both Hibari and Sagiri to immediately rescue Kogarashi by hugging him with their healing technique named the Soul Pouring Rain  while Yaya erases their presence.

Meanwhile, both Ouga and Nonko keep fighting to the point their spiritual armors are broken and they are almost naked because of this. Whilst watching the battle from the sidelines, Oboro states that whoever is stripped naked will be the loser-something makes Karura embarrassed. In her attempt to finish the duel as quickly as possible, Ouga has to feint her right punch-which forces Nonko to defend her right arm-and then kicks Nonko's left waist; weakening the Oni and reverts her to her normal state, making Ouga as the last Youkai standing. Fortunately, Kogarashi, alongside with Yaya and the Ameno Cousins, manages to rescue Nonko from the fall whilst explains that her reason for protecting her right arm. Seemly excited to see Kogarashi again, Ouga then complementing her former protege for having some friends.

### Visit to Katsuragi House for Answers

In Tokyo, the girls (Yuuna, Chitose, Chisaki and Koyuzu) and Suzutsuki eventually reach to Miria's penthouse but Miria herself isn't delighted to see the "uninvited visitors". The stories about Yuuna being a Garandou shocks Miria so much to the point berating the ghost for dragging her into the issue, though Yuuna responds by mentioning Ouga's motive in beating her. Apparently moved by Chisaki's friendship with the youkai even without her powers, Miria opts to tell the girls some information but before she can get to details, she tells Koyuzu possessing Chisaki. To the surprise of everyone (including Miria), however, Chisaki's possession is relatively easy successful despite the rocky effects as both Chisaki and Koyuzu are struggling to control the medium. Nevertheless, Yuuna asks Miria about House Tenko's true whereabouts without knowing that someone is watching the Katsuragi Residence from afar and reports her finding to Ouga via spiritual communication.

### Narrow Escape from Ouga

Meanwhile, Kogarashi tries to reason with Ouga and insist that Yuuna is not Garandou due to her good-hearted nature. However, Ouga refuses to give up her hunt as she claims that Yuuna's innocence has softened her resolve to the point even weaken her fists, with Oboro's remorse as her "proof". When she receives a call regarding Yuuna's whereabouts, Ouga immediately binds Karura and Oboro with one of her Spiritual Armor's shred pieces in order to seal their teleportation powers. As Ouga is leaving for Yuuna, Kogarashi rushes and attempt to stop her only to be beaten again due to his low spiritual energy.

With neither Karura nor Oboro are able to get out from Ouga's binding, as well as everyone's (including Kogarashi but not Yaya) weaken state, they have to use Yaya's cellphone to warn the others about Ouga's arrival. Just as Chitose is taking to the cellphone, however, Ouga arrives at Katsuragi Resident but, courtesy to Suzutsuki's teleportation, the group (along with Miria) narrowly escape from Ouga again which frustrates the Yatahagane.

### The Realm of Tenko House

As soon as the girls enter the hidden passage, they are astonished by the place's enormous environment where rocks are floating everywhere. At the same time, they also hear Tenko's voice who eagerly welcome its' visitors by telling them to follow the winds to its place. In order to do so, Koyuzu uses her power to create a Teddy Airship that enables them to follow the wind and the voice. When being asked by Chitose about meeting with her real family for the first time, to which the ghost replies that whilst she didn't know about her true family she still grateful to Chitose's 17 years of care for her.

Nonetheless, everyone is making haste for the voice before Ouga catches up but just as Miara ensures them that her entering Tenko's realm is impossible, the Yatahagane herself has already entered the realm with the help of the agent who happens to be the descendant of one of many branches of the Tenko House. After Suzutsuki is teleported by the agent, Ouga opts to defeat Yuuna and brings her back to

### **Yuuna's Awaken Power of Tenko**

#### Part 1

Despite Chitose's sacrifice in delaying Ouga's chase, the Yatahagane still manages to catch up the Teddy Ship whilst commenting the former's "foolishness". Fortunately, with her awaken power as Tenko Genryuusai, whilst floating in midair Yuuna manages to save Chitose from falling which she claims that she has given the greatest luck of all. As everyone is surprised to see Yuuna's unexpected power, the agent meanwhile warns Ouga that Yuuna has her Spiritual Armor restricted just like Ouga's. Intrigued by the awaken fox girl, Ouga wishes to take her on but before the duel, Chitose is sent back to Tokyo by Tenko Yuuna while the agent protects the ship with barriers. With the obstacles out of the way, the duels between Tenko and Yatahagane immediately ensues when Ouga charges at Tenko Yuuna when the latter's lightning still unable to even grazes her.

#### Part 2

During the duel between 2 strongest youkai, the Tenko agent comments that because of Ouga's increased experience since Garandou supposed demise, as well as Tenko Clans are notoriously known for being the weakest among the Three Big Families, she doubts that Tenko Yuuna will win against Ouga until the Yatahagane herself is suddenly sealed by one of Yuuna's power.

### The Truth About Yuuna and Garandou

#### Part 1

At Tenko's world, Yuuna, Ouga and the agent are trapped by the Garandou with the former two are powerless due to their sealed powers. The trio then confronts the stranger who, despite the agent's plea, refuses to let them go whilst explains that nobody would enter this realm while he plans to flee. Calling the stranger out for his cowardice, Ouga then asks the stranger's name and to her and the agent's shock, he replies that he is Byakuei Tenko- the founder Tenko House and one of the leaders of the Three Big Families. At the same time, he also reveals himself to be the creator of Garandou.

#### Part 3

Finding Byakuei's past experimentation as disturbing, Ouga then asks him about his goal to which he explains that his development of Garandou Techniques was to seek immortality so he can save his sicken daughter Mahoro-whose appearance look similar to Yuuna's. As he revealing Yuuna to be a copy version of Mahoro, Byakuei also explains his daughter's tragic state  and yearns to use his Garandou techniques to make Mahoro immortal since she is the only person he ever cherished the most.

Yuuna, who sympathizes Byakuei's suffering over his daughter's condition, calls him out for his twisted quest for immortality as well as his apathy to those who lost their lives because of his madness; along with her question about Mahoro's feelings when she sees her father's atrocities. Byakuei, however, considers his daughter's memories can be sealed again and ordering Garandou to devour Yuuna, Ouga and the Kuroe Agent.

### **Kogarashi's Arrival and Rescue**

Surprisingly, Kogarashi manages to reach Tenko Realm and witnessing the whole situation. Whilst she is relieved to see his arrival, Yuuna is also confused and asks him how'd he reach Tenko Realm, only to be nearly devoured alongside Ouga and Kuroe Agent. Kogarashi then jumps in and rescue the trio and despite Yuuna and Ouga warn him not to come, he eventually free all three of them from Garandou's clutches with his fist, which is a success. At the same time, Kogarashi also confronts Byakuei as he not only hears his reputation but also assuming him as the mastermind behind all of this commotion before being interrupted by a falling Yuuna.

Kogarashi's arrival prompts Byakuei to use his magic leaves to change him but they are blocked by Ouga, who then bestows half of her spiritual armor to Kogarashi as protection. Believing that he is at a disadvantage, Byakuei tries to escape via teleportation, only to be trapped by the barrier that is created by the Demon Slayer Army and Kuroe Agents.

### **Showdown Between Byakuei and Kogarashi**

Even being cornered by enemies from all sides, Byakuei manipulates Yuuna by saying her real name and using her to attack Kogarashi and Ouga. To free Yuuna from Byakuei's control, Kogarashi pounces onto the Tenko founder but when Byakuei commands Yuuna to retaliate, the latter is not responding to his command; forcing Byakuei to dispel Yuuna's power and attempt to kill her instead. Miraculously, Ouga rescues Yuuna from Byakuei's attack just in time and apologizes to her for the previous misunderstanding while calling her current name, before being sealed again.

### **Ouga Temporary Stay At Yuragi Inn and Passing**

#### Part 2

Outside the inn, Kogarashi meets up with Ouga who teases him for being her "first love", much to Kogarashi's embarrassment. At the same time, Yuuna, who finishes her bath earlier, accidentally eavesdropping the conversation and she is shocked to hear that Ouga tells Kogarashi that she loves him; prompting her assumption that Ouga as Kogarashi's "first love". To Yuuna's surprise, however, the relationship between Kogarashi and Ouga is more like a sibling as the latter reveals that the former was a loner before their first meeting.

## Notes

1. ↑  According to Ouga, during her way to the underworld she asked one Sanzu guardian about Garandou's whereabouts since she thought that the evil entity should've joined her to the other world. When Sanzu Guardian denied such a thing, Ouga immediately (and forcefully) escaped from the underworld and spent 2 years at the human realm in order to find the truth about Garandou.
2. ↑ Saragi's confusion stems from her memories where she was actually sent to the Yuragi Inn due to Nonko instead of Yuuna, meaning that Yuuna has already a resident before Nonko even lived there.
3. ↑ According to Chitose, a spiritual ripple is equivalent to a spirit's fingerprint.
4. ↑ Along with some lines, she further mentions that Garandou's apparent "demise" should have made Ouga passed on. The sudden revelation about Yuuna's relation with the Garandou made the situation even more ironic as
5. ↑ Whilst Kogarashi is still strong and durable like he is now, since he has saved the world by defeated Garandou, Ouga-in her own words-claimed that him had "surpassed" her back then. However, since he stopped training for over 2 years while Ouga did not, it made Kogarashi significantly weaker than she is.
6. ↑ The strategy has been made prior the revelation of Yuuna as a Garandou
7. ↑ The reason for Karura's berating Yuuna because she believes that Yuuna should've passed on and not lingering with Kogarashi, and the revelation about Yuuna as both Tenko and Garandou only complicating matters. The only reason why she reluctantly brushes that out is because of Kogarashi.
8. ↑  Although Yaya and the Cat Spirit can heal Kogarashi's physical wounds, they cannot replenish his spiritual power.
9. ↑  According to Sagari, there is a way for the Chumma Ninja to transfer their spiritual power to a victim with low spiritual power. That technique however requires a ninja's physical body contact with the victim-something holds Sagiri back as she deems it as embarrassing. It's only until Karura's words about her inability to heal people made Sagiri take the bet.
10. ↑ It revealed that by the time the trio have arrived to where Kogarashi has landed, Karura has already made some patches onto Kogarashi while berating them for being late. It didn't help any situation better was that she told the trio that she didn't know any healing techniques.
11. ↑ According to Oboro, whilst the spiritual armor can protect its users from any damages, it isn't entirely withstanding all kinds of attack. In fact, any damage the user .
12. ↑ According to Miria, in order to make the possession work, both the medium and the youkai must sync together by opening their hearts with each other-something Miria deems impossible. The only reason.
13. ↑ The problematic about the possession itself is because that medium shares 2 spirits in one husk of the medium.
14. ↑ According to Byakuei, Mahoro was a talented girl whose power surpassed even him but because of her being human, she was struck with a fatal illness that was not cured by any tactics. To make the situation worse, she was nearly dying .
15. ↑ These "disadvantages" includes Ouga's position as a ghost (Yuuna), her buxom (Hibari) and her old age (Karura). The latter two of Ouga traits concerns both Hibari and Karura as they assume that they are Kogarashi's "preference".
16. ↑ The reason why Sagari asks Ouga about Kogarashi's origins is mostly out of curiosity, not her feelings for him.
17. ↑ While Garandou was described as a huge evil entity, what made it even more dangerous is the fact that it can disguise itself by hiding the souls-the embodied ones-inside it's body without anyone even realizing it.
18. ↑ According to Ouga, in her time, one Yoinozaka had to drink at least 100 Sake in order to match with Yatahagane's prowess. Nonko's case was rather unique because she had to drink 1,000 sake to get even with Ouga-something that is unheard of from Ouga herself.
19. ↑ According to Ouga, Zakuro has been live in peace at another world and began his family since post-Garandou.
