Dan Da Dan characters

Dan Da Dan starts with a bet. Momo Ayase believes in ghosts but not aliens, while her classmate Ken Takakura, known to everyone as Okarun, believes the opposite. Each goes to a haunted or UFO-linked spot to prove the point, and they find out that both are real. Momo awakens psychic powers, and Okarun ends up carrying the spirit of a yokai. This page covers 12 characters from the first two seasons in three circles: the friends who form Momo and Okarun's group, the yokai who cross their path, and the aliens who invade their town. Each profile stops where the character is introduced, with no spoilers.

Protagonist

Momo Ayase 綾瀬桃

Ayase household · Japanese voice: Shion Wakayama

Momo Ayase is a strong-willed high school girl raised by her grandmother, a spirit medium. She believes in ghosts and laughs at anyone who believes in aliens, until aliens abduct her. Afterwards she gains psychic powers: she sees the auras of people and objects and can grab and move them as if she had giant hands. Japanese voice: Shion Wakayama.

Ken Takakura (Okarun) 高倉健(オカルン)

Japanese voice: Natsuki Hanae

Ken Takakura, called Okarun, is a shy boy with no friends who loves UFOs and anything occult, which is where the nickname comes from. His friendship with Momo starts with the bet about ghosts and aliens. After an encounter with Turbo Granny, he gains a fast, powerful form when he draws on her strength. Japanese voice: Natsuki Hanae.

Main characters

Aira Shiratori 白鳥愛羅

Japanese voice: Ayane Sakura

Aira Shiratori is the most popular girl at school and believes she is chosen to fight evil. She arrives suspicious of Momo and Okarun and confronts them, convinced they are on the wrong side. She is vain, dramatic and full of certainty, but she gradually grows closer to the group and shows a more sincere side. Japanese voice: Ayane Sakura.

Jin Enjoji (Jiji) 円城寺仁(ジジ)

Japanese voice: Kaito Ishikawa

Jin Enjoji, known as Jiji, is Momo's childhood friend and her first crush. He is outgoing, good-humoured and a little clueless, and he arrives at the end of season 1 asking for help with strange happenings at his family's new house. His arrival unsettles Momo and makes Okarun insecure. Japanese voice: Kaito Ishikawa.

Mentors

Seiko Ayase 綾瀬星子

Ayase household · Japanese voice: Nana Mizuki

Seiko Ayase is Momo's grandmother and works as a spirit medium. She knows a great deal about curses and yokai and becomes the group's adviser. She is blunt, grumpy, easily flattered and refuses to admit that aliens exist, but she genuinely protects Momo and her friends. Japanese voice: Nana Mizuki.

Supporting characters

Turbo Granny ターボババア

Yokai · Japanese voice: Mayumi Tanaka

Turbo Granny is a foul-mouthed yokai who haunts a tunnel and appears in the first arc. She takes something very precious from Okarun, and getting it back becomes the duo's goal for several episodes. After they face her, she ends up stuck inside a lucky-cat figurine at the Ayase house, where she comments on everything. Japanese voice: Mayumi Tanaka.

Kinta Sakata 坂田金太

Japanese voice: Daichi Fujiwara

Kinta Sakata is Okarun's classmate, a withdrawn and very imaginative boy who loves science fiction, aliens and giant robots. He appears late in season 2 and gets involved with the group just as a huge monster shows up in town. He is over-the-top and dramatic, which makes for strong comedy scenes. Japanese voice: Daichi Fujiwara.

Taro

Yokai · Japanese voice: Tomokazu Sugita

Taro is a school anatomical model who has come to life and lives at Momo and Okarun's high school. He is completely in love with Hana, another anatomical model who lives at the Ayase house. He appears at the end of season 1 and throughout season 2, always as comic relief. Japanese voice: Tomokazu Sugita.

Antagonists

Evil Eye 邪視

Yokai · Japanese voice: Mutsumi Tamura

The Evil Eye, called Jashi in Japanese, is a resentful yokai tied to the area around Jiji's new home. It is at the centre of season 2's first arc and gives its name to the compilation film released before that season. It is unpredictable, childish at times and very dangerous at others. Japanese voice: Mutsumi Tamura.

Acrobatic Silky アクロバティックさらさら

Yokai · Japanese voice: Kikuko Inoue

Acrobatic Silky is a tall, long-haired yokai with extremely fast movements who appears in Aira's arc in season 1. She pursues the girl obsessively and is one of the strongest threats the group faces early on. The episodes focused on her are among the most moving in the series. Japanese voice: Kikuko Inoue.

Serpo aliens セルポ星人

Aliens · Japanese voice: Kazuya Nakai

The Serpo are the aliens of the first episode, who abduct Momo and change her life. They use clones, appear in groups and act ridiculous and threatening at the same time. They prove to Momo that aliens exist and return to cause more trouble later in season 1. Japanese voice: Kazuya Nakai.

Dover Demon (Mantis Shrimp alien)

Aliens · Japanese voice: Tomokazu Seki

The Dover Demon is a mantis-shrimp-like alien who appears late in season 1 as a dangerous mercenary. He fights Momo, Okarun and Aira in battles full of twists. Later he returns to the story in a far more comic role, picking up a nickname of his own among the characters. Japanese voice: Tomokazu Seki.
