Wending his way home after a bender one evening, master moocher and game programmer Keita Ibuki decides to satisfy a craving for ramen at a noodle stand. Instead of slurping soup, though, he surrenders his meal to a manic girl who, unbeknownst to Keita, is a Mototsumitama, a guardian of the coexistence equilibrium. When his new acquaintance is attacked, Keita gets caught in the crossfire and loses an arm... moreWending his way home after a bender one evening, master moocher and game programmer Keita Ibuki decides to satisfy a craving for ramen at a noodle stand. Instead of slurping soup, though, he surrenders his meal to a manic girl who, unbeknownst to Keita, is a Mototsumitama, a guardian of the coexistence equilibrium. When his new acquaintance is attacked, Keita gets caught in the crossfire and loses an arm. Awakening from the shock, Keita finds himself back in his apartment, arm intact! But just whose arm is it?! less

Balancing a normal existence and an unbreakable pact with a divine being is anything but easy. Much to his chagrin, Keita is discovering this the hard way. Try as he might to distance himself from recent events, Keita can't shake Kuro, the mototsumitama who saved his life... moreBalancing a normal existence and an unbreakable pact with a divine being is anything but easy. Much to his chagrin, Keita is discovering this the hard way. Try as he might to distance himself from recent events, Keita can't shake Kuro, the mototsumitama who saved his life. But when the stakes get higher and another human-mototsumitama pair comes looking for a fight-one with Keita's childhood friend, Akane, as the prize-Keita is forced to reevaluate his attitude and stand by both his old and new friends. Who will emerge victorious? less

When he discovers that all the new faces springing up lately are not enemies but friends, Keita Ibuki receives the guidance (and the goods) from his new allies to take on the evil behind the false alter-egos that have been appearing with alarming frequency. But not only must Keita now face a new enemy with Kuro, he must also revisit the painful memory of his mother and her disappearance when their new quest takes him to his mother's hometown of Okinawa.

After overcoming the initial shock of seeing his dead mother in a recent photograph, Keita travels to Okinawa with Kuro and Akane. Following a reunion with his karate-master grandfather, Keita and company are led to an island where they meet twin feral Mototsumitamas. Though they're initially hostile, it seems the twins hold a piece of the puzzle that will bring Keita and his companions closer to the truth about the aims of the ruthless Shishigami... moreAfter overcoming the initial shock of seeing his dead mother in a recent photograph, Keita travels to Okinawa with Kuro and Akane.

Though they're initially hostile, it seems the twins hold a piece of the puzzle that will bring Keita and his companions closer to the truth about the aims of the ruthless Shishigami. But as they get closer to that truth, Keita comes face-to-face with his mother?! Or is she...? less

Still in Okinawa, Kuro and the twins unvover a Shishigami plot to systematically destroy sources of tera around the world! But the conflicted Keita isn't really in a position to be much help as he juggles getting to know his mother's doppeliner, Shinobu, with fulfilling his duties as Kuro's partner. But when the Shishigami invite Keita to join them, will that be enough to snap him out of his confusion?

Kuro opens up about her life before she came to Earth, that of a carefree princess in her family's haven of pure tera. But factions emerged among the mototsumitama, and now the violent betrayal that destroyed her clan drives her search for the head of the Shishigami family. The mutual tragedy of their pasts draws Keita and Kuro closer together - this fight has become personal for both of them... moreKuro opens up about her life before she came to Earth, that of a carefree princess in her family's haven of pure tera.

The mutual tragedy of their pasts draws Keita and Kuro closer together - this fight has become personal for both of them. But will their bond of trust give them the strength to take on the Kaionji Group as Kouei's sinister plot unfolds in Okinawa? less

Having systematically destroyed all the protective soul stones in Japan, Hiyou reveals his plot to gather alter egos together and unleash a massive wave of negative energy that could threaten the entire country. The last soul stone is in Okinawa - the stone once guarded by Makana and Kakuma's family. With Kuro and Keita detained at the resort and Kakuma captured by Tribal Ends, Makana's ready to step up and defend the pure place of his fallen relatives... moreHaving systematically destroyed all the protective soul stones in Japan, Hiyou reveals his plot to gather alter egos together and unleash a massive wave of negative energy that could threaten the entire country.

With Kuro and Keita detained at the resort and Kakuma captured by Tribal Ends, Makana's ready to step up and defend the pure place of his fallen relatives. But a lone Mototsumitama may not have the strength to oppose the evil at work... less

In the heat of battle, Keita and Kuro learn that Shinobu is a minus root-one who must absorb the tera of others lest she be overcome by the raw negative energy within her. With Shinobu latched on to Keita, Kuro is unable to summon her strength as Keita's power is drained away. As no one stands in his way, Hiyou destroys the Hiba family's soul stone, releasing a tidal wave of negative energy that threatens to engulf Okinawa. Is there anyone left to protect the island?

With the danger in Okinawa now passed, Keita, Kuro, and Akane return to Tokyo. Though Kuro and he were ultimately victorious in Okinawa, Keita worries that his own weakness is holding back the team and begins training even harder to face the battles that lie ahead. Unfortunately, more than danger is looming on the horizon. A roaming mototsumitama wanders into town, causing as much of a fuss as Kuro did when she first arrived in Keita's life!

Accosted by an agent of the Shishigami clan, Keita and Kuro have no choice but to fight. The duo seems to be holding its own against the mototsumitama Aragi, but it's too early to celebrate. Just as Kuro manages to take Aragi down, his contractee shows up, eager to wrap things up as quickly as possible. Keita crumbles as Aragi's contractee unleashes her thousand, the Gravi Doom, and with their synch broken, Kuro is left alone to face the unrelenting Aragi... moreAccosted by an agent of the Shishigami clan, Keita and Kuro have no choice but to fight.

Even if she emerges from the fight alive, will her confidence remain intact? less

Mikami may have slipped through the Kaionji Group's fingers once, but they aren't about to let her escape again! Before she can make her getaway, Saishu of the Shishigami clan takes out Mikami's beloved Ferrari, forcing her to face him in battle. Enraged, Mikami readily leaps into the fight, but without a contractee even the fierce mototsumitama is no match for Saishu's skillful attacks. Excel watches in tears as her only precious friend is bloodied and beaten.. moreMikami may have slipped through the Kaionji Group's fingers once, but they aren't about to let her escape again!

Excel watches in tears as her only precious friend is bloodied and beaten...which rouses memories of another person she once held very dear... less

In spite of weeks of training with Keita, Kuro crumbles at thereappearance of the mototsumitama Aragi. But just as Kuro is prepared tosubmit to death, someone calls out to her from deep within her...In themidst of her terror, Kuro feels the presence of Keita's grandfather andKakuma, who died protecting their home in Okinawa, as well as hermother, who saved Kuro in her final hour... moreIn spite of weeks of training with Keita, Kuro crumbles at thereappearance of the mototsumitama Aragi.

Their actions helped fortifyKuro in the past, but will their words give her the strength she needsto draw upon the full extent of her power and defeat her most fearedenemy? less

With Mana on board, Keita is outnumbered five girls to one guy in the modest Tokyo apartment. Although Mana has been welcomed in as part of the "family," her disdain for humans and mototsumitama who ally with them is more than evident. A glimpse into the past reveals the cause: Mana's beloved older sister abandoned her right to clan leadership - and her little sister - to raise a family with the human she had fallen in love with... moreWith Mana on board, Keita is outnumbered five girls to one guy in the modest Tokyo apartment.

A glimpse into the past reveals the cause: Mana's beloved older sister abandoned her right to clan leadership - and her little sister - to raise a family with the human she had fallen in love with. Can Mana set aside her resentment to help Kuro and Keita find and defeat the elusive Ghost? less

Though Mana is somewhat able to counteract the effects of the Tribal Ends' tranquilizer, victory against Kaien seems impossible in her weakened state. But Mana would rather admit defeat fighting on her own than accept the help offered by Kuro, Keita, and Arie... moreThough Mana is somewhat able to counteract the effects of the Tribal Ends' tranquilizer, victory against Kaien seems impossible in her weakened state. But Mana would rather admit defeat fighting on her own than accept the help offered by Kuro, Keita, and Arie. Will the strict laws of her clan prevent Mana from seeing all that the coexistence equilibrium encompasses - both human and mototsumitama - and the possibility of camaraderie between them? Will a newly forged bond between mototsumitama and human be what ultimately saves them all?! less

Despite Kuro and Mana's best efforts, the two high mototsumitama are no match for Shion, one of Reishin Shishigami's top generals. Amused by Mana's arrogance, Shion reveals that the proud purebloods are actually an impure breed descended from the original mototsumitama, who gave up the purity of their race in order to survive. Without the powerful battle genes of her ancestors, Kuro cannot hope to defeat Shion, let alone Reishin... moreDespite Kuro and Mana's best efforts, the two high mototsumitama are no match for Shion, one of Reishin Shishigami's top generals.

Without the powerful battle genes of her ancestors, Kuro cannot hope to defeat Shion, let alone Reishin. Filled with rage, Kuro launches a ferocious attack unlike anything the others have ever seen. Has Kuro unlocked some hidden power of her own, or will this sudden surge of bloodlust take her out of commission for good?! less

Kuro and Keita's glimpse into the past has left them with more questions than answers. Their path clouded with uncertainty, the partners seek another audience with Ghost to gain a better understanding of what they have seen and what lies ahead. If it is indeed true that humans and mototsumitama exist outside the will of tera, then perhaps Reishin Shishigami's end goal is starting to make its own kind of sense...But does the will of tera truly demand such a high price from humanity?

In the pure home of the Shishigami clan, Kuro and Keita prepare to face Reishin Shishigami and stop him before his terrible vision for the future is realized... moreIn the pure home of the Shishigami clan, Kuro and Keita prepare to face Reishin Shishigami and stop him before his terrible vision for the future is realized. Despite what Kuro and Keita know about the shared history of humans and the mototsumitama and the events that led to mototsumitama dominance, Reishin's plot to downsize the human population is too cruel to bear! But in the heart of the Shishigami's territory, an unexpected enemy arises to decisively correct the imbalance of the world-the ancient genuine ones themselves! With such mighty foes before them, do Keita and Kuro have the strength to change the fate of all mankind?! less
