Tenka Izumo/Synopsis

## The Mato Exhibition Games

After Kyouka Uzen encounters a Humanoid Shuuki while on a mission, Tenka and her Vice-Chief, Yachiho Azuma, visit the 7th Unit dorm. Upon her arrival, Tenka meets Yuuki Wakura, the 7th Unit's housekeeper and Kyouka's rumored "Slave", and she takes an instant liking to him. Tenka, Yachiho, and the 7th Unit gather in the meeting room where Tenka explains that she wishes to discuss the new orders from headquarters regarding Kyouka's discovery of the Humanoid Shuuki, which stipulate that Units should cooperate more frequently. During the discussion, Yachiho belittles and demeans her sister, Himari Azuma, Vice-Chief of the 7th Unit, but Tenka tries to change the subject by mentioning that the 3rd Unit was defeated, supposedly, by a different Humanoid Shuuki. Still, Yachiho continues to mock Himari, which results in Kyouka proposing an exhibition match between the 6th and 7th Units, which Tenka agrees to. Tenka and Yachiho then depart to prepare for the match.

A few days later, Tenka and her subordinates, Yachiho and Sahara Wakasa, return to the 7th Unit for the start of the exhibition match. After the preparations are completed, the two units gather outside the 7th Unit dorm and prepare to face off. Ginna Bizen from the 10th Unit acts as the referee and puts up a barrier via her Ginna Club ability that will heal all injuries of those within and keep out any invading Shuuki. The first match commences with Yachiho going up against Himari (and Yuuki as her "Slave"). Yachiho fights fiercely, but is ultimately defeated by Himari, and Tenka takes the defeat in stride, seeing it a lesson for her team. Tenka discusses the match with Yachiho, giving her guidance on how to improve her performance, but also notes that, based on his selflessness during the match, Yuuki is a true "slave". Shortly afterwards, the second match begins with Sahara facing off against Shushu Suruga. Ultimately, Sahara prevails against Shushu, providing a victory for the 6th Unit.

Abruptly, a swarm of Shuuki and a mysterious figure identifying himself as Rairen appear and break down Ginna's barrier and attack. Using her Ame-no-Mitori ability, Tenka transports Ginna and Nei Ookawamura to safety before transporting back to join the ensuing battle. During the battle, Yachiho battles Rairen one-on-one, but she is overpowered by the invader. Before Rairen can finish her off, Tenka arrives in time to save Yachiho and takes over the fight for her. Tenka informs Rairen that she has already eliminated most of the Shuuki, allowing Yachiho to escape, and that she is aware that Rairen has two other comrades nearby. Tenka battles Rairen and, though he puts up a formidable fight, Tenka is able to dodge and toss him around with her Ame-no-Mitori. After teleporting Rairen into the air, she creates a massive vortex that sucks him in, as well as most of the surrounding Shuuki, seemingly destroying him.

Once the remaining Shuuki have been defeated, the 6th and 7th Units and Ginna reconvene. Tenka and Kyouka observe that there are still the two enemy commanders that are unaccounted for and conclude that the Mato Exhibition Games have ended in a tie. With that, Tenka and the rest of the 6th Unit take their leave.

Having developed an attraction to Yuuki, Tenka uses her Ame-no-Mitori to enter his bedroom one night and watch him as he sleeps.

## Tenka's Desire

Kyouka, Yuuki, and Himari visit the 6th Unit dorm for a meeting and Tenka takes special notice of Yuuki. Tenka and Kyouka meet alone and discuss their strategies for dealing with Shuuki and Humanoid Shuuki. Afterwards, Tenka boldly requests to have Yuuki for herself. Tenka reasons that she has always been bored when alone and wants a loyal companion, but Kyouka is reluctant to give up Yuuki and suggests alternatives. Still, Tenka insists that she wants Yuuki specifically and, seeing that Tenka will not back down, Kyouka stands firm that she will not give up Yuuki. Tenka makes one final offer to support Kyouka in the upcoming Commander election, but Kyouka still refuses. Tenka asks if she can at least meet Yuuki in private, and Kyouka replies that she will not intervene.

Later that day, Tenka surprises Yuuki by appearing in his room via Ame-no-Mitori and abruptly asks if he will go out with her. Yuuki is flattered, but unsure whether or not Tenka sees him as a "pet". Tenka attempts to seduce Yuuki and clarifies that, while she sees him as a "pet" now, she may see him as more if he grows stronger. Tenka then gives him a tender kiss, which overwhelms her as well and she pushes him on to bed as she starts to take his clothes off. As Tenka examines Yuuki's body, she asks him to confirm his feelings and, flustered, he replies that it is too soon for him to proceed. However, Tenka teasingly says this means she still has a chance with him and tries to seduce him even more. However, they are suddenly interrupted as Shushu barges into Yuuki's room to inform him about a Shuuki attack.

Caught in the act, Tenka joins the rest of the 7th Unit outside and apologizes to Kyouka for causing a disturbance. Kyouka transforms Yuuki and the two defeat the invading Shuuki. Aftewards, Tenka returns to the 6th Unit dorm, still very interested in Yuuki.

## 7th Unit Training

Tenka meets with Kyouka in the human world to discuss recent orders from their Commander, instructing them not attack any Shuuki nests as she wishes to negotiate with the Humanoid Shuuki. While Kyouka is resistant to this order, Tenka believes there is a possibility they could learn more about Mato if they can negotiate with the Shuuki. Tenka also informs Kyouka that the Chiefs' Assembly will be called soon, giving them an opportunity to express their thoughts. Their meeting ends with Tenka agreeing that it is unlikely the Humanoid Shuuki will respond to them and assuring Kyouka that she has the support of the 6th Unit.

## The Hidden Village

When Yuuki is kidnapped by three Humanoid Shuuki, Tenka, along with Yachiho and Sahara, join up with the 7th Unit to rescue him. As Yuuki was kidnapped while in his Slave form, Kyouka's body forcibly moves towards him after he changes back, effectively working as a guide to his location. Tenka and the others follow her to the secret entrance of the Hidden Village where Yuuki has been taken. A swarm of Shuuki suddenly appear and attack and Tenka teleports Kyouka, Himari, Yachiho, and herself inside the Hidden Village, leaving Shushu and Sahara to deal with the Shuuki. Tenka and the others navigate the caves of the Hidden Village and come upon a room with another group of Shuuki, which Himari and Yachiho stay behind to fight.

After exploring the caves further, Tenka and Kyouka finally locate Yuuki who is with the lead Humanoid Shuuki and Kidoumaru, the One-Horned Shuuki that destroyed Kyouka's home town. Tenka grabs Yuuki and teleports the three of them away with Ame-no-Mitori. Finally reunited, Kyouka gives Yuuki his Slave reward and Tenka joins in, wishing to reward Yuuki as well. However, they are interrupted as the Humanoid Shuuki and One-Horned Shuuki appear. Before they can attack, however, Yuuki blocks their way and convinces the Humanoid Shuuki to talk with Tenka and Kyouka.

Yuuki explains the situation to Tenka and Kyouka, revealing that the Humanoid Shuuki is, in fact, his sister Aoba Wakura. He also explains how the Humanoid Shuuki in the Hidden Village were experimented on by the Onmyou Agency and they now seek vengeance. Although Kyouka assures Aoba that she will do everything in her power to stop the Onmyou Agency, Aoba still insists that the Humanoid Shuuki will do as they please and is unconvinced that Kyouka or Tenka will be able to do anything about the Onmyou Agency. Seeing that they are at an impasse, both sides agree they will have to settle the matter by force. Before the battle commences, Tenka tells Aoba that she is dating Yuuki and calls her "sister", which enrages Aoba. Aoba then restrains Yuuki with her hair so he will not take part in the battle. Tenka asks Aoba if she is really sure about fighting them and Aoba informs her that she and the other Humanoid Shuuki have someone who can not only heal them, but reverse their condition and they plan to find someone who can strengthen her power and lift the curse permanently. That being the case, Tenka suggests that they work together, but Aoba once more refuses.

As the fight begins, Kyouka faces off against Kidoumaru, while Tenka battles Aoba. Aoba proves to be a very powerful and fast opponent, making it difficult for Tenka to pin her location. As Aoba attacks, Tenka is able to teleport herself away to dodge her, which results in Aoba causing damage to the cave. Despite Tenka's warnings, Aoba eats a Peach in order to power up. As Tenka takes stocks of Aoba's abilities, Aoba goes on the offensive once more forcing Tenka to constantly dodge with Ame-no-Mitori. Since she can teleport hundreds of times without tiring, Tenka plans to hold out until Kyouka defeats Kidoumaru and can aid her. As the battle continues, Tenka tricks Aoba into kicking Kidoumaru and Kyouka breaks Aoba's rhythm by slashing her with her sword. Tenka then lands a hit on Aoba with her vortex and prepares to finish her off, but hesitates as she does not wish to seriously hurt Yuuki's sister. Aoba then unleashes a devastating energy blast, hitting Tenka dead-on and causing her to collapse in defeat. Aoba asks Tenka why she didn't finish her off, to which she replies that it would have made Yuuki sad, which pleases Aoba. Elated that she has gained Aoba's approval, Tenka imagines a future in which she and Yuuki date, get married, and have a child, with her "sister" Aoba by their side. Tenka calls Aoba sister once more, but Aoba still insists she not call her that. Kyouka rushes to Tenka's aid and, although she is not mortally wounded, Tenka can no longer fight.

Suddenly, Aoba's comrades Koko Zenibako and Naon Yuno arrive, with Yachiho, Sahara, Himari, and Shushu right behind them. Abruptly, the cave begins to shake violently and the ceiling opens up to reveal the two enemy commanders Nei had seen during the Mato Exhibition Games; Shikoku and Jouryuu. Shikoku introduces herself and Jouryuu as the Eight Thunder Gods. The Humanoid Shuuki and the remaining 7th and 6th Unit members fight against the gods, but they are overwhelmed by their incredible strength, with Yachiho, Sahara, Himari, and Shushu being knocked out. Amidst the chaos, Tenka helps Kyouka free Yuuki and manages to get back on her feet. The Thunder Gods retreat, having abducted Koko and Naon, and Kyouka destroys Kidoumaru.

As the cave begins to collapse, Tenka, Kyouka, and Yuuki gather Yachiho, Sahara, Himari, and Shushu, and Tenka teleports them out of the cave to safety. Tenka returns shortly afterwards as Yuuki and Kyouka talk with Aoba. Aoba clarifies that she no longer plans to attack the Onmyou Agency, now wishing only to save Naon and Koko. Furthemore, also she trusts Tenka and Kyouka, Aoba still does not trust the Anti-Demon Corps altogether and will instead move to another village with the rest of the Humanoid Shuuki. Tenka agrees with Aoba's decision, believing it is a difference of ideologies as their commander Ren Yamashiro is very patriotic and is likely colluding with the Onmyou Agency. However, Kyouka remains hopeful that she will become the next Commander of the Anti-Demon Corps, at which point the Humanoid Shuuki will be able to come out of hiding, which Aoba agree with. As another earthquake hits, Tenka, Kyouka, Yuuki, and Aoba part ways before the cave collapses.

Three days later, Tenka enters Yuuki's bedroom and seductively lies on top of him as he awakens, claiming that she wished to show him she had made a full recovery. Abruptly, Yuuki grabs her and then proclaims his gratitude for everything she did. Having expected a romantic confession, Tenka is somewhat disappointed, but accepts his thanks. Suddenly, Kyouka enters and, finding Tenka and Yuuki in a compromising position, irritably reminds Tenka that she should be busy with the reports. Tenka concedes and says they will meet again at the Chiefs' Assembly.

## Training With the Chiefs

On the day of the Chiefs' Assembly, Tenka goes to 10th Unit Headquarters and joines her fellow Chiefs in the conference room, as well as Yuuki who has accompanied Kyouka. Commander Ren Yamashiro then arrives, taking notice of Yuuki, and the meeting begins. The 1st Unit announces the appointment of Konomi Tatara as the new Chief with Riu Myouga stepping down to become Vice-chief. Ren then brings up the topic of the Thunder Gods, mentioning that Tenka defeated one of them, but Tenka clarifies that she cannot be sure she killed him. Based on the evidence they've observed, Ren orders that if any of the Units are attacked by the gods, the Chiefs must team up to defeat them. Kyouka objects, arguing they must take a more proactive approach, but Ren refutes her suggestion and Kyouka concedes. As the meeting continues, Ren brings attention to Yuuki, informing the other Chiefs that he is necessary for Kyouka's Slave ability.

Suddenly, Ginna interrupts the meeting, informing the Chiefs that a Shuuki army has appeared. Ren dispatches four of the Chiefs, who easily defeat the Shuuki and Ginna identifies the masterminds behind the attack. Ren goes off to deal with them, ordering Kyouka to follow her. After Ren defeats the masterminds singlehandedly, she returns to the meeting with, Kyouka rejoining sometime later, at which point Ren quickly concludes to the Chiefs' Assembly. Tenka and the rest of the Chiefs return to their dorms.

Later that night, Tenak teleports into Yuuki's room once more, but finds that Shikoku has infiltrated the dorm and is attempting to abduct Yuuki. Tenka strikes her with Ame-no-Mitori and then joins Shushu who also snuck into Yuuki's room and is now trying to defend him. Shikoku releases a hallucinogenic gas that traps Tenka and Shushu in an illusion, leaving them helpless as she attempts to kill them. However, Tenka breaks through her illusion just in time and attacks. Shikoku dodges, but she is then struck by Shushu who has also broken the illusion. Shikoku retreats and swears vengeance on Shushu for attacking her. Once Shikoku is gone, Yuuki awakens and Tenka informs him that one of the Eight Thunder Gods entered his room and gives credit to Shushu for acting first.

Sometime later, Tenka and the rest of the 6th Unit, along with the 7th Unit, arrange to meet with the 5th Unit for a training session. Yakumo Ezo, Chief of the 5th Unit, arrives at the 7th Unit dorm with her suborinates Kaiko Itsuki and Saki Tokoyama. Though Yakumo engages in her usual promiscuous behavior, Tenka shrugs her off and focuses on the upcoming training. The three Units begin a rigorous training session and, once they are done, relax in the hot spring. To prevent her from groping the other girls, Tenka and Kyouka tie Yakumo up in a closet, but this leads to an encounter between her and Yuuki. Yakumo is able to free herself, become acquainted with Yuuki, and then peeks on Tenka and the other girls as they come out of the bath. Tenka and the 6th Unti depart for training with the 10th Unit shortly afterwards.

## The Azuma Banquet

During another Chiefs' Assembly, Tenka begins to suspect that Ren has taken an interest in Yuuki, fully aware that that will make things difficult for him. After the meeting, Tenka presses Kyouka about whether she has learned how to lend Yuuki, but Kyouka angrily replies that Yuuki is too tired to be lent out. Tenka merely expresses her sympathy for Yuuki and clarifies for Kyouka that, while she does want to borrow Yuuki, she doesn't want to rush things. The two are then approached by Fubuki Azuma who wishes to talk with Kyouka.

Later, at the 7th Unit dorm, Tenka meets with the 7th Unit and discusses the upcoming Azuma Banquet that will decide the next head of the Azuma Family, for which Fubuki has recruited Yachiho and Himari to participate. They discuss the history of the Azuma's as they relate to the Anti-Demon Corps, with Kyouka observing that Tenka has a good connection with them. They also discuss Yuuki's Slave form while being used by Ren with Tenka remarking that it could be dangerous to use that form again. As Yuuki happily recalls a massage he received from Fubuki, Tenka and the other girls try to massage him as well to prove their worth.

Some time later, Tenka, Yachiho, Kyouka, Himari, and Yuuki arrive at the Azuma Estate for the Azuma Banquet. They are greeted and escorted by Tobera Azuma, the current head of the Azuma Family. Tenka assures Tobera that she wanted to be present to support Yachiho, after which she presents Tobera a box of treats as a gift. After joining up with the other contestants, Tobera announces the start of the Azuma Banquet. Tobera activates a portal that sends Yachiho and the other contestants to a remote island where the battle will be held, while Tenka, and Tobera stay behind to watch the battle.

As the Banquet unfolds, Himari and Yuuki go up against Homare Azuma and, after a fierce battle, they emerge victorious against her. Shortly afterwards, four of the contestants, including Homare, are brought back to the estate, having been eliminated, and Tobera announces that the "main dish" is about to begin as Himari faces off against Fubuki. Pushed to the edge after Fubuki insults Kyouka's leadership, Himari awakens the hidden power of her Learning ability, which greatly impresses Tenka and the others. Although she puts up a valiant fight, Himari is still not strong enough to beat Fubuki. Yachiho and Maia Azuma, the last remaining contestants, willfully yield and the Banquet ends with Fubuki being declared the new head of the Azuma Family.

Afterwards, As Fubuki takes command of the family, she asks for Tenka's continued cooperation with the family, which Tenka happily agrees to.

Sometime later, Tenka visits Aoba to give her updates on Yuuki's activities. Aoba is delighted and thanks Tenka for checking in on her, even though she knows it puts her position at risk.

## Battle in Yokohama

Towards the end of summer, Tenka joins the 7th Unit (minus Himari) in a trip to the beach for summer break. Although she is not part of the 7th Unit, Tenka tells Kyouka she just wanted to go to the beach for a break. After enjoying a relaxing fun-filled day, Tenka departs and returns to her normal duties.

Not long afterwards, Tenka is called to 10th Unit Headquarters to answer an emergency call regarding the Eight Thunder Gods. While walking through the hallways, Tenka encounters Yuuki and escorts him to the conference room to "protect" him from the other Chiefs. During the meeting, Tenka and the other Chiefs are informed that a Thunder God has been abducting actresses in Yokohama. Mira Kamiunten is put in charge of the mission to the subjugate the Thunder God and rescue the actresses, with Kyouka assisting her.

Tenka is later ordered to assist Kyouka and Yuuki in the mission as the Thunder God, Kuusetsu, has devoured Mira and absorbed her ability. Tenka arrives at the scene of the battle where Aoba has joined the fight and Kuusetsu has cloned herself via Mira's All-Killing and summoned a giant Shuuki. Tobera and Maia Azuma also arrive and Tobera baits a large number of Kuusetsu's clones into attacking them. The giant Shuuki is then suddenly destroyed by a humongous energy blast, which Tenka and Kyouka realize is the doing of Ren. Meanwhile, Tobera eliminates Kuusetsu's clones with her Transience ability. Tenka eliminates some of Kuusetsu's clones with Ame-no-Mitori, eliciting praise from Yuuki, which gives Tenka a boost of confidence as she faces more of the clones. Meanwhile, Aoba grabs the original Kuusetsu and hits her with a humongous energy blast, but Kuusetsu withstands it. Seeing the scene from afar, Tenka tries to attack Kuusetsu, but Kuusetsu fires her feathers at her, forcing Tenka to dodge. A Kuusetsu clone emerges from the ground and grazes Tenka, causing her to realize that Kuusetsu has set traps by hiding her clones underground. Another swarm of clones dive in to attack Tenka. Meanwhile, Kyouka and Yuuki battle the original Kuusetsu and manage to free Mira, Naon, and Koko from her body. After Kyouka seemingly destroys Kuusetsu, Aoba makes her escape with Naon and Koko and Tenka pretends to attack them to keep up appearances with the rest of the Anti-Demon Corps.

Two days later, Tenka teleports Kyouka and Mira to the 7th Unit dorm as Yuuki, who fell unconscious at the end of the battle, has finally awoken. The three give Yuuki their thanks for his help during the battle. As the Slave reward takes effect, Tenka volunteers to participate and assist Kyouka with the reward. Mira similarly volunteers, but, seeing that she is incredibly embarrassed by the prospect, Kyouka tells her she doesn't have to. Tenka and Kyouka then lead Yuuki to the hot spring where the three of them strip naked. Inside the bath, following Kyouka's lead, Tenka kisses Yuuki while pressing her body against him. During the reward, Yuuki informs Tenka and Kyouka that he supposedly had an encounter with Kuusetsu who has entered his mind. However, since they cannot confirm whether it was a dream and since it poses no immediate threat, Tenka and Kyouka agree that Yuuki should just keep them informed of any changes.

Later, Tenka reappears to Yuuki in his room and teleports him to the Hidden Village. There, Yuuki happily reunites with Aoba, Naon, and Koko. While Yuuki visits with his sister, Tenka and Aoba explain that Tenka was the one who brought Aoba to Yokohama and that she has been giving supplies to the Hidden Village. After Yuuki expresses his gratitude to Tenka, she and Aoba excuse themselves to discuss the Humanoid Shuuki's situation with the Anti-Demon Corps. Tenka informs Aoba that the Anti-Demon Corps are overlooking them for the time being as they are preoccupied with the Shuuki that attacked Yokohama.

Later, Tenka attends a Chiefs' Assembly meeting, where the other Chiefs observe that the incident in Yokohama has caused a public uproar. Ren declares that they will make a Mato Emergency Announcement to better prepare themselves for the Thunder Gods.
