Rokumon (六文) is Rinne's black cat by contract. These cats form contracts with Shinigami, aiding them in their job, eliminating evil spirits, but also bringing curses, threats, and ill omens.


Rokumon has three known forms: humanoid, demon, and kitten. In each form, he retains his black fur and green eyes.

His regular humanoid form is a small, black, bipedal cat with a human face. In his demon form, he is a giant cat head with a trail of clouds behind him.

He can also transform into a small adorable kitten. He does this to gain food, since his contract with Rinne does not provide a high income. Rokumon also seems to think the the handouts are better than what Rinne has to offer.


Rokumon is very loyal to both Rinne and Tamako, addressing Rinne as "Rinne-sama". He does what he can to help Rinne with his expenses, but sometimes his methods are a bit extreme; once, he tried to injure a large mass of students just so they would make donations to the weather hutch. His intentions are good, though, however misguided his actions aren't.

He also has the notion that Sakura is Rinne's "woman", and dislikes Tsubasa for obvious reasons.


Rokumon's contract

Rokumon wishing to form a contract with Rinne

He first appears to Rinne at the abandoned club building of Sankai High, claiming to have been sent by Tamako to form a contract with him, to which the boy refuses, having no resources to support the helper. He then appears to Sakura, whom he grew attached to and reveals further about Tamako's engagement and Rinne's situation to her, while Rinne finds a letter, discovering the truth about him: Tamako fired him and advised him to get Rinne's support. Eventually, the two form a contract, on the grounds that Rokumon covers his own living expenses.

While supporting his master and struggling together against his poverty, he would go through various occurrences, which some are significant for him. He lets Sakura ride on top of his head whenever she gets involved in serious situations (and also Tsubasa). He would meet other Black Cat Contractors such as Oboro, Suzu and Kurosu, and participate in events involving Black Cats with them.

Rokumon at the Black Cat Test

Rokumon at the Black Cat Ranking Exam

Rinne allowed him to take the Black Cat Contractor Ranking Exam, since there’s a new discount on Shinigami Tools for a ranked Black Cat. He got a good score on the Written Test and reached top on the Combat Test, and so graduated to 1st Rank, and he was chosen as the MVC (Most Valuable Cat) and given a lucky cat piggy bank as a bonus reward.[1]

He almost inherited Kuroida’s treasure box, which actually contains his 700 years of debts, but he thankfully sensed the same stench of Rinne’s poverty in it and denied it.[2]

Rokumon Pizza

It is revealed that he had been hiding his savings from Rinne in a cupboard at a tool room at the corner of the school building and made up a ghost story to keep the students away, which eventually lured a ghost teacher from another High School, who causes his secret to be discovered. Rinne forgave him but Rokumon would not give any money.[3]

He accepted to pose as Annette’s mascot in a witch coven, but ends up being an unwilling participant to a fusion magic spell and has his torso turned into a pizza, and it took a lot of trouble to revert the spell.[4]

After Rinne reunites with his mother, having lastly reincarnated into a human girl called Ichigo, Rokumon would sometimes give his services to her in exchange for food.[5]

When the Black Cat Secret Meeting took place with no knowledge of its purpose and Oboro assumed it as a protest rally against the Shinigamis, he felt he did not have any complaints over his master, but after the real purpose of this meeting is discovered, he fought Rinne to get his Scythe to open a giant can, but his master opens it himself, and they both collapse in disgust like everybody else. For being the youngest black cat, he would be entrusted the box containing the records of the Black Cat Secret Meeting until the next century, though he declines it.[6]


Rokumon is usually the one who fetches new equipment for Rinne.

Rokumon doesn't seem to have any special abilities besides transformation and travel between the two worlds. He can change into a large, frightening cat demon and a small kitten. In his demon cat form, he can fly around and allow people to ride on top of his head.


Rinne Rokudo

As Rinne's contract cat, Rokumon is required to aid Rinne unconditionally. But even before thet formed a contract, Rokumon has a deep respect for Rinne. Rokumon states that Rinne is "cool" when he acts selflessly, however, Rokumon also thinks Rinne is "lame" whenever he acts childish when receiving money.

Sakura Mamiya

Rokumon enjoys being with Sakura and respects her deeply, often perching on her shoulder and even referring to her as "Sakura-sama." This may be because his sense of duty to Rinne carries over to Sakura since he believes Sakura and Rinne would be a good couple.

Tsubasa Jumonji

Rokumon sees Tsubasa as Rinne's love rival, therefore taking a disliking the exorcist. Rokumon dropped the honorific in Tsubasa's name shortly after their meeting.


As the human reincarnation of Rinne's mother, he respects her calling her "Ichigo-sama" and provides her Shinigami tools when she asks.

  • Rokumon is written with the kanji for "six mon", "mon" being an old form of currency. This is a reference to the amount of money (six mon) needed to cross the Sanzu no Kawa, the Japanese version of the River Styx.
  • Unlike the cute little characters before him (Shippo, Ten-chan) he doesn't show any animosity towards Rinne, instead he shows great respect towards him and likes helping him out.
  • The black cat ranking system is most likely a reference to the ranking of fox demons in Inuyasha (making Shippo his obvious counterpart).
