Koko Zenibako/Synopsis

## The Hidden Village

Following Aoba Wakura's plan to retrieve her brother, Yuuki Wakura, from the Anti-Demon Corps 7th Unit, Koko disguises herself as an ordinary human and pretends to be the victim of a Mato disaster. When Himari Azuma and Shushu Suruga of the 7th Unit come to her aid, Koko reveals her true nature and attacks them. Koko summons Kumadouji along with a small swarm of Shuuki. Aware that Koko is a Humanoid Shuuki, Himari attempts to negotiate with her, but Koko refuses and insists on fighting. Himari fires a barrage of bullets at Koko via her Learning ability, but Kumadouji blocks them. Koko counters by trying punch Himari with a devastating blow, but Himari dodges. Naon Yuno and Akura soon arrive to assist Koko. Meanwhile, Aoba intercepts Kyouka Uzen and Yuuki as they rush to the aid of their comrades and Aoba successfully reclaims her brother. Koko and Naon retreat and return to the Hidden Village.

With Yuuki in their custody, Koko heals Yuuki by licking his body all over while Naon stands by. Aoba enters the room and, upon finding Koko licking her brother's naked body, she physically punishes her, demanding an explanation, but Naon explains that Koko was only healing Yuuki, after which Aoba apologizes. Once Yuuki is healed and dressed, Koko, Aoba, and Naon show him the Hidden Village, explaining that it is within a large cave system that runs through Mato and has many Peach trees. They further explain that all residents of the Hidden Village are Humanoid Shuuki like them, and they are all former humans (while also reassuring Yuuki that regular Shuuki were definitely never human). Aoba tells Yuuki he can live in the village with them and not be a "slave" anymore, but Yuuki protests, claiming the Anti-Demon Corps can protect Aoba and the other Humanoid Shuuki. However, this enrages Koko, Aoba and Naon as they declare that the Anti-Demon Corps is their sworn enemy, while also informing Yuuki they plan to attack a certain research institute.

After Aoba explains to Yuuki how she was able to locate him, his stomach abruptly starts growling and Aoba fetches him something to eat. Yuuki asks Koko and Naon if it was hard for them to deal with Aoba's personality, but they assure him that, although she can be bossy, she is a reliable leader. As Koko eats one of the Hidden Village's mushrooms, Yuuki becomes captivated by its smell, but Naon warns him that normal humans should not eat it as they are not sure what effect it will have. However, just from smelling it, Yuuki begins to hallucinate and sees Naon's breasts as meat buns. Losing his senses, Yuuki grabs and sucks on them. Koko attempts to intervene, but Yuuki sees her buttocks as a peach and grabs for her. Upon Aoba's return, Koko and Naon are stuck in the compromising and mortifying position of having their buttocks and breasts pressed against Yuuki's face.

Later, once Yuuki is back to normal, he apologizes to Koko and Naon and they quickly forgive him. Aoba then summons Kidoumaru, Kumadouji and Akura. Aoba, Koko, and Naon introduce Yuuki to them, explaining how they are able to control them. Upon Yuuki's inquiry, Aoba explains that, while she is the leader of the Humanoid Shuuki, she does not control all Shuuki, nor does she know if the Shuuki have a master. Yuuki then asks how Aoba, Koko, and Naon turned into Humanoid Shuuki. Naon explains to Yuuki how she, Koko, and several other women were transported to Mato and turned into Humanoid Shuuki after eating a Peach, after which they were taken by the Onmyou Agency and cruelly experimented on. Yuuki suggests that the Humanoid Shuuki denounce the Onmyou Agency, but Koko, Aoba, and Naon explain that they have already tried, to no avail, as the Onmyou Agency is incredibly influential. Yuuki further protests, claiming that the Anti-Demon Corps can help, but Koko and the others are still unconvinced as they are sure the Commander of the Anti-Demon Corps is already aware of the Anti-Demon Corps' activities. Suddenly, Aoba senses that the Anti-Demon Corps have arrived and tells Koko and Naon to prepare for battle.

Koko and Kumadouji arrive just outside the Hidden Village and join a group of Shuuki that have already gathered to combat two of the Anti-Demon Corps, Shushu and Sahara Wakasa. As the battle begins, Sahara activates her Crazy Sheep ability, and Koko charges at her with a barrage of attacks. Once she has an opening, Sahara punches back, but Koko makes her skin slippery, causing Sahara's punch to slide off her. Koko then kicks Sahara into the air, making her an easy target for Kumadouji, but Shushu, using her Paradigm Shift ability, grows giant and stops him. Shushu tries to crush and stomp Kumadouji in her hands, but his body proves sturdy enough to resist her and he manages to get away. Koko explains to Shushu and Sahara that Kumadouji's body is hard as rock and she herself can control her bodily fluids. Shushu tries to crush Koko with a giant boulder, but Kumadouji attacks her from behind and Koko breaks free of the boulder with her injuries quickly healed. Frustrated, Shushu mentions that she wants to save Yuuki, which Koko overhears. Koko informs Shushu that she licked and healed Yuuki and that their boss is treating him with "love", which creates a series of suggestive images in Shushu's mind, angering her. As Koko and Kumadouji go on the offensive, Shushu grabs Sahara and apparently retreats. However, as she escapes, Shushu shrinks down and Sahara tosses her towards the approaching Koko and Kumadouji. Shushu flies straight into Kumadouji's mouth and, once inside his body, grows to giant size, breaking him apart from the inside. Sahara then defeats Koko using one of Kumadouji's fangs. Shushu chastises the defeated Koko for stirring up a "maiden in love". Afterwards, while Shushu battles a giant Shuuki, Koko and Kumadouji rapidly recover from their injuries, and Koko decides she must regroup with Aoba.

Koko and Kumadouji manage to escape and rejoin Naon. The three regroup with Aoba and Kumadouji, who are facing down Kyouka, and they inform Aoba of their defeat. They are soon-after followed by Shushu, Sahara Himari, and Yachiho Azuma who had pursued them. Suddenly, two figures, a black-haired girl (Shikoku) and a winged woman (Jouryuu), burst through the ceiling and descend. Jouryuu grabs Aoba and Naon and Shikoku introduces herself and Jouryuu as the Eight Thunder Gods who control the Shuuki. Aoba struggles and tries to attack Jouryuu, but she is thrown aside. Koko assists Naon as she tries to attack the Thunder God, but they are stopped when Shikoku summons a swarm of mystical snakes that wrap around them and bite them, putting Koko and Naon into a deep sleep. Despite Aoba's efforts to rescue them, Koko and Naon are abducted by Jouryuu.

Koko and Naon are taken to the Eight Thunder Gods' lair where Shikoku, Jouryuu, and Rairen present their still-unconscious bodies to the egg-like Thunder God, Kuusetsu. Koko and Naon are quickly devoured whole by Kuusetsu, with the other Thunder Gods remarking that this will allow Kuusetsu to grow and Koko and Naon will serve as "living batteries" for its body.

Aspects of Koko's and Naon's appearance and personalities, as well as their abilities, are later inherited by Kuusetsu as she takes on a humanoid form.

## Battle in Yokohama

Koko and Naon (along with Mira Kamiunten, who was also absorbed) are eventually rescued by Kyouka and Yuuki as they utilize a technique that allows Yuuki to penetrate Kuusetsu's body and free them from her. The unconscious Koko and Naon are subsequently retrieved by Aoba who then makes her escape.

Two days later, Tenka Izumo teleports Yuuki to the Hidden Village, and Koko, alongside Aoba and Naon, greet him happily. While Yuuki visits with them, Koko and Naon express their gratitude to Yuuki for saving them. While Aoba and Tenka take their leave to discuss other matters, Yuuki asks Koko and Naon how they are doing and they reply that they are fine, although their bodies have been a bit sluggish. Yuuki then volunteers to give them a massage, which proves incredibly effective and instantly re-energizes them.
