Riku Amami
Jinki Form 
Riku is the story's protagonist and a high-school student who lives with his father (absent for most of the story) and stepmother, Shizuru. He was in love with Shizuru's younger sister, Amane, but she is presumed to have died two years ago in a fire at Kazama Hospital. He receives a text message from her phone address and goes to the place of her death, providing the setting for the start of the series.

After sustaining, near start of the series, a fatal wound from a Kanshuu, Neene turns Riku into a special Kanshuu that can retain his own consciousness as long as he has a Jinki.

Rena Arisugawa Ootori
Jinki Form 
A young Jinki user who is depicted as a quiet and serious person focused on her job, who frequently takes the lead when fighting Kanshus. After Youhei's death, she becomes Riku's partner, whom she appears to have become attracted to, after their meeting with the Source of Infection. She is a Lost Rebound victim; her entire family was killed in Hatsumi Island during the original infection and became Kamogari.

Grown Up 
Neene was hatched from a cocoon at the start of the story, and grows at a rapid rate, experiencing a growth spurt occurring each time she uses her powers in a Kanshuu fight. A mysterious entity who has an uncanny resemblance to Riku's dead aunt Amane. Neene recognizes Riku as her "papa" and later Rena as her "mama".

As the series progresses, she demonstrates various powers, such as turning Riku into a Kanshuu after he is wounded in a fight and creating a giant ball of light that disintegrates anything inside it. She is eventually revealed to be a Kyuuki/Coffin Princess, a queen Kanshuu who receives the memories stolen by other "drone" Kanshu, and she grows as she absorbs more memories.
  • The Cutie
  • Daddy's Girl: Neene. Played for laughs. Later also Mommy's Girl with Rena.
  • Famous Last Words: "Liar".
  • Happily Adopted: By Riku, who becomes her papa. She later "adopts" Rena as her mama.
  • Heroic Sacrifice: Neene sacrifices herself to stop rampaging Ende, and was narrowly saved by Amane. Made more poignant with her calling Riku a liar, while it is clear that he has begun to sincerely care for Neene, not just as Replacement Goldfish for Amane.
  • Identical Stranger: She strongly resembles Amane, prompting people to think that she must be Amane's daughter or at least a close relative. The truth is that her nature as a Kyuuki means that she is actually Amane, or more exactly that she will become Amane.
  • Plot-Relevant Age-Up: Neene grows faster than a normal child. She ages as she absorbs memories, otherwise her growth rate is akin to that of a normal human.
  • Replacement Goldfish: Takao tells Riku that if he raises Neene she'll grow up to become Amane. But as the story advances Riku begins to care for Neene as just herself, "his daughter", and not as a replacement for Amane.
  • Rose-Haired Sweetie
  • She Is All Grown Up: After a three months Time Skip after her supposed death she appears to have grown older, looking the same age as Amane, in fact it may be because Amane's ego has woken up.
  • Shipper on Deck: Riku is her papa and Rena is her mama.
  • Sprouting Ears: Neene does this at crucial moments. Normally they are also present, but closed.
  • Supernatural Gold Eyes
  • Token Mini-Moe
  • Younger than She Looks: She is born looking already like an almost two years old child. And as the story advances she keeps growing older, even though she should only be a few weeks old.
