Mahoraba

Note: All characters are voiced by Satomi Arai.

Kozue Aoba (蒼葉 梢, Aoba Kozue)

Landlady of Narutaki Sou and Ryūshi's 16-year-old second cousin. She attends the same high school as Tamami. She has several different personalities that come out when she experiences different emotions, but returns to her original one after sleeping or passing out. In the manga, she begins going out with Ryūshi in chapter 39. Near the end of the manga, it is revealed that the cause of her different personalities is her sad past where she lost everyone that she loved, starting with the death of her great grandfather and her later abandonment by her parents. It is further revealed that her other personalities were influenced by the 10-year-old Ryūshi who showed her his drawings and taught her that people can be anything in their imagination.

In the epilogue, it is shown that she and Ryūshi are married and have four kids, each of them similar to one of her four alternate personalities.

Saki Akasaka (蒼葉 梢, Akasaka Saki)

Saki has a tough attitude and is very strong physically. Despite this, she actually does care about others, even if she is embarrassed to admit it. She appears when Kozue is surprised or angered. She is an extreme lightweight, and unable to tolerate anything but umeshu (in the manga), in the anime she can't even smell liquor without passing out.

Nanako Kanazawa (金沢 魚子, Kanazawa Nanako)

Nanako is usually better behaved after she becomes "Shiny". One other noteworthy feature of Nanako is that of all the other personalities that Kozue goes through, Nanako is the only one given an actual age. According to the manga, Saki, Chiyuri, and Natsume all are of unknown age, though it is safe to assume that all of the others have the same age as Kozue.

Chiyuri Midorikawa (緑川 千百合, Midorikawa Chiyuri)

Chiyuri loves cosplay and also makes everyone else cosplay against their will, but only if it is against their will. If they don't care or want to do so, she doesn't want to. She appears when Kozue is clumsy or frightened. While she is in this personality, Tamami acts as her assistant, whom Chiyuri refers to as "my partner", while supplying Tamami many embarrassing photo-ops with which to fill her camera. Tamami, in return, calls Chiyuri "my sweetheart". "Correct!" is her catchphrase.

Natsume Konno (紺野 棗, Konno Natsume)

Natsume has a very shy personality who initially avoided speaking to anyone at all. She is extremely skilled at sleight of hand and card tricks. The first time she talked was when teaching Ryushi a trick. Flowers will spontaneously pop out of the top of her head when she's happy. She has a habit of ending her sentences with "kamo", meaning either "maybe" or "I think" depending on the context.

Tamami Chanohata (茶ノ畑 珠実, Chanohata Tamami)

Voiced by: Yui Horie

Tamami is close friends and classmates with Aoba Kozue. She always has a camera and likes to take pictures of Kozue in embarrassing situations. She is also an inactive member ("Ghost member") of the occult club, along with Kozue. Tamami is very strong physically, although she appears quite normal, if not short and weak. A perpetually smiling evil genius, Tamami is cold, sarcastic, cruel, manipulative, inconsiderate and condescending towards those she deem to be her moral/intellectual inferiors; which in other words mean everybody besides Kozue-Chan and her other personalities. This is explained by her usually being isolated for her extreme genius before meeting Kozue. Tamami goes to Seika Tandai Fuzoku High School with Kozue, and has a habit of saying "desu" at the end of her sentences. In the manga, it is revealed that she is actually a very emotional person, crying all the while during Momono's departure. At the end of the manga, she becomes a world-class photographer who frequently travels oversea.

Ryūshi Shiratori (白鳥 隆士, Shiratori Ryūshi)

Voiced by: Ryōko Shiraishi

The main protagonist of the series, who is an aspiring children's book artist. Ryūshi moved into Narutaki Sou so he could attend the Sumeragi Design School in Tokyo. Aoba Kozue is his second cousin. He met Kozue when they were younger, but doesn't remember this at the start of the series. He is childish and passive to the point of never objecting when anyone does anything wrong to him, which happens a lot. In the epilogue, he is shown to have married Aoba Kozue, with four daughters, possibly representing Aoba's former personalities.

Megumi Momono (桃乃 恵, Momono Megumi)

Voiced by: Masumi Asano

Megumi attended Washida University for one year, but it turned out to be too expensive, so she took a year off. Her hairstyle features an ahoge. She stays at Narutaki Sou all the time and is in a long distance relationship with her middle school boyfriend who is studying cinema overseas. She's also a heavy drinker, and likes to party with Johnny in Shiratori's room, much to his dismay. In the epilogue, she is shown with one daughter, Ruri, who is a fan of Ryūshi's children's books. In the anime, she remains at Sou Narutaki, telling her boyfriend to ask her to join him again once he has finished his studies and fulfilled his dreams.

Sayoko Kurosaki (黒崎 沙夜子, Kurosaki Sayoko)

Voiced by: Mioko Fujiwara

Sayoko has a very dark personality and is not very responsible. Her father is a rich and talented sculptor, with whom she became estranged in her youth over her choice of her husband; rather than let her parents choose a fiancé for her, she eloped with the estate's gardener. Her favorite food is Mizuyōkan. Despite her evident uselessness throughout the series, she really cares for Asami.

It should also be noted that despite her poor skills in living, she possesses great skill in chess (which Momono notes is a useless skill in life) and in the arts (capable of making art pieces out of almost anything—sand, snow, wood, and even food), giving evidence that she seems to have inherited her father's skills. At the end of the manga, she is working as a freelance sculptor, making an expensive looking wooden dragon. It is also revealed that she isn't really lazy or bad at working but rather, simply has low or no confidence and motivation.

Asami Kurosaki (黒崎 朝美, Kurosaki Asami)

Voiced by: Umi Tenjin

Asami lives in room 5 with only her adopted mother since her adopted father died when she was younger. She keeps things together in spite of her mother's problems, pulling most of the workload at home and keeping track of expenses.

Yukio Haibara (灰原 由起夫, Haibara Yukio)

Voiced by: Kenyuu Horiuchi

Yukio doesn't speak directly, but rather uses ventriloquism to speak through his puppet, Johnny. In the anime, he is at one point mistaken for Aleister Crowley by Vermilion, to his and Johnny's considerable distress. Yukio Haibara became Kozue's caretaker after her parents abandoned her at Narutaki Sou. In the manga, Haibara speaks using his own voice only once when he expresses his hope that Shiratori can heal Kozue.

Johnny Ryūsei (流星 ジョニー, Ryūsei Jonī)

Voiced by: Kenyu Horiuchi

Yukio Haibara's hand puppet of a brown dog through whom Yukio speaks using ventriloquism. They both act as if the puppet were really the one speaking; Johnny often "speaks" as if Haibara is the extra part. It is revealed near the end of the manga that Johnny was "born" when Haibara was at a loss as to how to get the sad and lonely Kozue to talk to him after her parents left her.

• Miyabi Shirogane (銀 雅, Shirogane Miyabi) is Shiratori's teacher. Students who are disobedient or forget their homework are subjected to "the mysterious closet", which apparently is a frightful ordeal. She has a habit of having her eyes half open and talking very cheerfully until certain moments. At one point she and Tamami meet and get along quite well, much to the others' terror. She typically wears kimonos and "normal" clothes on festivals.
• Tsubasa Yamabuki (山吹 翼, Yamabuki Tsubasa) is Shiratori's classmate who is always trying to charm high school girls and young women. He happened to meet Shiratori when he was dressed as a girl due to a prank and fell in love with "her". Without a name to call this newfound love, he nicknamed her "Reiko", not realizing that she was really Shiratori. Voiced by: Hikaru Tokita
• Risona Aizawa (藍沢 理想奈, Aizawa Risona) is Shiratori's classmate who wears glasses. Her name is based on the famous bank in Japan "Resona Bank". A devoted fan of manga (especially yaoi and yuri manga), Risona aims to become a dojinshi author. She has a fear of white goats eating her manga manuscripts. Voiced by: Riku Moriyama
• Mizuho Amane (亜麻根 瑞穂, Amane Mizuho) is Shiratori's classmate who uses her batting skills to punish Tsubasa for his womanizing. She normally uses a spiked baseball bat, but because of the adults' circumstances, her bat was taken away and replaced with a plastic megaphone. In the epilogue of the manga, she is shown to have become an editor, despite studying to be an author. Voiced by: Nozomi Masu

• Erika Vermilion (エリカ·バーミリオン, Erika Bāmirion) (Voiced by:Shizuka Itō)

She is the head of the occult research lab, of which Tamami, as well as Kozue are technically members. She is never named and only referred to as "club president (ぶちょう, Buchō)" until the final chapter of the manga. "Erika Vermillion" is a stage name for her fortune-telling business. She has a masochistic slant as well, and enjoys Tamami's talent for insults and other unusual tortures. When at a shrine, she is strangely purified into a person exactly opposite (bright and kind, to a point of using a lot of money to wish for happiness of everyone).

• Hiro Utsugi (空木 尋, Utsugi Hiro) (Voiced by: Sayaka Kinoshita)

Orchestra club president and conductor, who is the younger sister of Sakura.

• Satsuki "Sa-chan" Matsuba (松葉 五月, Matsuba Satsuki) is Asami's classmate and speaks in Kaisai dialect. She tries to keep control of Mi-chan's haughty attitude, often using heavy texts such as dictionaries or telephone books as punishment. Voiced by: Akeno Watanabe
• Michiyo "Mi-chan" Asagi (浅葱 三千代, Asagi Michiyo) is Asami's classmate and is rich and slightly snobby, often having a blase attitude and striking old-fashioned poses with her fan. Even if Michiyo won't freely admit it, she just wants to be friends with Asami. Voiced by: Riku Moriyama

• Asahi "Asabi" Chigusa (千草 旭, Chigusa Asahi)

She works for the bakery, which is famous for its taiyaki.

• Hwang Yo "Yo-chan" Lee (黄有麗 (ホァンヨウリー), Hoan Yō Rī)

She works for the bakery, but is notorious for going through several, vastly unrelated jobs in quick succession — most likely because she is known for frequent slip-ups. She was previously a department jewelry store clerk, fortune teller, lifeguard, and various other jobs. She calls herself Hanako Suzuki.

• Grocer / Yaonaga

He runs various prize games with items such as futon warmers and refrigerators as prizes. He often tells bad jokes and puns, mostly for his own amusement.

Sayoko's father and an established and wealthy sculptor. He has a tendency to be controlling.

• Yu Minazuki (水無月 夕 Minazuki Yū; voiced by: Kotono Mitsuishi)

Sayoko's mother, who cannot stand sunlight, and is therefore much more active at night. Yū Minazuki walks with a cane, which she applies to her husband's feet when he is rude.

• Mahiru Minazuki (水無月 まひる Minazuki Mahiru)

Sayoko's younger sister and Asami's aunt, though they are closer to sisters in terms of their relationship. Mahiru Minazuki has been living in Italy since childhood, so she is somewhat awkward at speaking Japanese. She speaks little, and tends to employ a kind of formal monotone when she does.

• Tachibana (タチバナ)

The senior maid of the Minazuki household. She is an extremely skilled maid and is a capable martial artist and especially skilled with projectile weapons such as darts. Despite her tough appearance, she has a soft spot for things like teddy bears. She is very conscious of her height, thinking herself to be too tall (at the shrine, her wish is to shrink). She is extremely protective of Mahiru.

• Sakura Utsugi (空木 桜 Utsugi Sakura; voiced by: Yuka Inokuchi)

A maid of the Minazuki household. While her heart is in the right place, she is extremely careless and clumsy, a flaw which often lands her in trouble. In the epilogue, her little sister works as a maid in the house with her.

• Chauffeur

The personal chauffeur of the Minazuki household.

• Tobita Haruka

An artist who happens across Sayoko's carvings. After multiple attempts to track her down, she is now producing and selling sculptures with Sayoko whom she considers to be a genius.

A set of 22 tarot cards with Mahoraba's characters exist. The drawings are done by the author, and in addition to original cards, others such as mass-production versions (simplified background), fake tarot cards (different pictures for card number), and special editions (holographic) exist. These are supplements for related merchandises, and cannot be collected in its entirety solely by buying the books; thus, it is hard to complete the collection.
