Memoria Pretty Cure Episodes




Unbeknownst to its residents, Lost River— after the passing of its beloved elder Tokiba— has fallen into great danger. Prince Chaménos is given the responsibility of bearing all of the missing and repressed memories of humans in reality, and finally fulfill this purpose as Lost River's ruler. With its biggest threat— the invasion of a hive-minded race called fractal beings— considered to be long passed, the prince is ready to dismiss the land's guardian Cure Pyramid from her duties. However, the Ministry of Research's sudden disappearance signals that something unpleasant is about to befall Lost River.

Within days, Lost River is overrun with monsters called Frangeres, and Cure Pyramid's help proves to be an asset to the preservation of the land's people. Chaménos suspects that the Frangeres are products of the Ministry's research on fractal beings, and his suspicions are quickly confirmed when their leader Argand reveals her intentions to the prince, announcing the formation of the Lost Heart Company. Her eyes are set on the Magna Horologium— Lost River's ancient clocktower whose archives hold important memories from throughout the universe's entire history— which reveals that somehow, Argand has acquired the same control over memory that Chaménos has. After a gruelling fight for survival in the crumbling Lost River, Cure Pyramid is left utterly defeated with her Curologe shattered, and Chaménos himself is left powerless to do anything. With Chaménos at her mercy, Argand’s conquest for memories seems to have reached its finale, until abruptly, the Magna Horologium screeches to a halt. Lost River is plunged into stasis, rendering the young prince amnesiac, and a dark, unsettling silence falls upon the realm.

Prince Chaménos and Cure Pyramid are nowhere to be found, and the people of Lost River are left to fend for themselves against Argand’s Frangeres. Two young fairies— Tempo and her older brother Rythmo— are quick to seek shelter after their home is destroyed by the monsters. During their escape, the pair discovers the entrance to an underground workshop beneath the rubble of Lost River’s Castle Town, and find the five remaining Curologes sitting on a worktable alongside a sealed letter from the recently deceased Tokiba. When it seems they are about to get a moment's rest, another strange phenomenon appears in the workshop. What looked to be an inane empty doorframe seconds earlier is observed by the siblings to be a portal, and without warning, Tempo-- along with the Curologes-- is pushed in. Her brother's cries still barely ringing in her ears, Tempo finds herself in the new bedroom of sixteen-year-old Kohri Niwahara-- whose closet is a gate between Lost River and reality.


Pretty Cure

  • Kohri Niwahara (庭原小織 Niwahara Kōri?) - A cheerful 16-year-old girl in her second year of high school. Kohri's usual disposition is rather sunny— she makes a great effort to get along with everyone she meets, refusing to judge based on looks alone, and in spite of occasional bashfulness on her part. Even though she is quite upbeat, her self worth is lacking, leaving her a bit of a recluse. Being the shrinking young girl she is, she will often sit and listen to what others have to say with little resistance. Listening is what Kohri is great at, however— she has very high empathy and deals well with other people's problems, even if subconsciously they can put a damper on her own positive attitude. Kohri's specific interests span almost every corner of modern media, which makes her a great conversation starter in the event that she takes interest in someone (or vice versa, they take interest in her). Kohri channels the spirit of the Hanging Gardens of Babylon to become Cure Spring (キュアスプリング Kyua Supuringu?). Her theme colour is pink.
    • CV: Asami Seto / Heather Hogan
  • Takumi Arashi (嵐匠 Arashi Takumi?) - A rebellious 16-year-old in his second year of high school. Takumi is a bit of a delinquent, and intends to own his less than favourable reputation, however far that may take him. Outside appearances suggest he's abrasive, loud, easily distracted, and having an appearance that's a little rough around the edges serves to compound that, but behind all of his cocky parading is a much different character. Any disregard for authority he puts up is mostly for show, and Takumi has a lot of respect for the people he trusts. Those people also get to see a Takumi who is more playful than threatening, albeit a bit of a frivolous idiot at times. Takumi has a very particular mindset; the more thought put into his actions, the more susceptible he is to overthinking things and stressing out to an unhealthy degree, meaning his impulsivity is more a result of him practically being on pins and needles at all times, and not necessarily a lack of reason. Takumi channels the spirit of the Statue of Zeus to become Cure Volt (キュアヴォルト Kyua Vu~oruto?). His theme colour is blue.
    • CV: Toshiyuki Toyonaga / Max Mittelman
  • Seren Torano (寅野星恋 Torano Seren?) - A peculiar 16-year-old in her second year of high school. First impressions paint Seren as a very pragmatic, academically-successful student, and while those are sound descriptors, she is much, much more than that. Seren is rarely seen without a smile on her face, and her intuition and eye for character is almost supernatural, leading others to believe she has some sort of ESP. Somehow, even her reckless confidence in her own bombastic ideas seems incredibly calculated, and thus destined to succeed. She tends to be frustratingly dismissive about her quirks, however, and remains a brick wall when it comes to people prying at her personal life. Even though many have trouble grasping Seren's overall personality, she is surprisingly easy to get along with, and likes helping others in more "subtle" ways. Seren channels the spirit of the Temple of Artemis to become Cure Luna (キュアルナ Kyua Runa?). Her theme colour is white.
    • CV: Rie Takahashi / Alexis Tipton
  • Hounomaru Yutaka (湯高炎丸 Yutaka Hōnomaru?) - An unassuming 16-year-old in his second year of high school. Before losing both of his legs in a devastating accident, Hounomaru was the star of Kinjin's basketball team; a year after the event, he has been rendered rather emotionally vacant, as his last passion for living dwindles. He puts on the air of being a benign and cool-headed person, but getting close to him will reveal his general unhappiness and a recently-forged, sickeningly-sour worldview. Although he insists there's nothing particular about him that should warrant curiosity, he is actually very multitalented— the aforementioned athletics have been made difficult as of late, but his grades across the board are exceptional, and he happens to be very well-spoken. His short fuse is something he himself denounces, and he's quick to apologise for any undeserved outbursts. As the new vice president of the "Earth Rehabilitation Club", Hounomaru lives a generally languid life punctuated by Seren's antics. Hounomaru channels the spirit of the Colossus of Rhodes to become Cure Sol (キュアソル Kyua Soru?). His theme colour is red.
    • CV: Yuusuke Kobayashi / Xander Mobus
  • Nemu Reimatsu (霊松眠夢 Reimatsu Nemu?) - A sardonic 16-year-old in her second year of high school. Nemu channels the spirit of the Mausoleum at Halicarnassus to become Cure Grave (キュアグレーブ Kyua Gurēbu?). Her theme colour is purple. (WIP)
    • CV: Yumiri Hanamori / Stephanie Sheh
  • Prince Chaménos (カメノスさま Kamenosu-sama?) / Kousei Eigami (永上光世 Eigami Kōsei?) - The crown prince of Lost River. Chaménos channels the spirit of the Lighthouse of Alexandria to become Cure Wick (キュアウィック Kyua U~ikku?). His theme colour is yellow. (WIP)
    • CV: Mitsuki Saiga / Yuri Lowenthal
  • Iroha Kinjin (金人紅葉 Kinjin Iroha?) - A mellow 18-year-old in her third year of high school. Iroha channels the spirit of the Great Pyramid of Giza to become Cure Pyramid (キュアピラミッド Kyua Piramiddo?). Her theme colour is brown. (WIP)
    • CV: Megumi Toyoguchi / Connor Kelly-Eiding


  • Tempo (テンポ Tenpo?)
    • CV: Kaede Hondo / Cassandra Lee Morris
  • Rythmo (リズモ Rizumo?)
    • CV: Yoshimasa Hosoya / Chris Patton

Lost Heart Company

  • Argand (アーガンド Āgando?) - The chairwoman of the Lost Heart Company. Prior to the destruction of Lost River by her hands, Argand worked directly under Prince Chaménos as the "Head Minister of Research", partaking in various experiments involving fractals. Argand, being as candid as they come, aims to steal the memories held in the Magna Horologium in hopes of one day completing her research and harnessing the powers of fractal beings— control over reality. Inexplicably, Argand has the powers over memory that Chaménos holds, and Tokiba once held. Furthermore, she seems to have more control over it than they do, being able to alter the memories of other people as well.
    • CV: Ryouka Yuzuki / Elizabeth Maxwell
  • Newton (ヌートン Nūton?) - The vice-chairman of the Lost Heart Company who is all but as deceptive as Argand herself. Newton's cunning is even more unsettling in the face of his loyalty to his chairwoman.
    • CV: Yuuichirou Umehara / Liam O'Brien
  • Mandelbrot (マンデルブロ Manderuburo?) - A young man kept on a tight leash by Argand. He is taciturn and serious, rarely giving away his thoughts, leading the more laid back members of the Lost Heart Company like Trion and Lyapu to tease him about his aloof demeanour. Although he is stern, he does not give orders to his subordinates (which is the main reason Lyapu is so attached to him). Mandelbrot is totally amnesiac, and cares less about researching fractal beings than he does finding his lost memories, and figuring out how he lost them in the first place. He feels inclined to trust Argand, but he still feels uneasy around her.
    • CV: Saito Soma / Joe Zieja
  • Lyapunov (リャップノフ Ryappunofu?) - A young man who follows Argand. He is very lazy and couldn't be any less proactive than he already is for the group. He spends most of his time badgering Mandelbrot. He discourages his co-workers from calling him by his full name, and usually goes by "Lyapu."
    • CV: Keiji Fujiwara / Frank Todaro
  • Julia (ジュリア Juria?) - Two young women with completely opposite dispositions. They operate exclusively as a unit as they are actually the same person and share the same mind. To distinguish between the two, the more lively of the two is referred to as Julia A, while the more solemn one is referred to as Julia B. Lyapu came up with this distinction and he is very proud of himself for it.
    • CV: Ayaka Ohashi / Michelle Ruff (A) and Megan Lee (B)
  • Rössler (ロッスラ Rossura?) - The Lost Heart Company's silent assassin. He rarely speaks aside from short, often one-word sentences.
    • CV: Tomokazu Sugita / Sam Riegel


  • Frangere (フランジャ Furanjya?) - Monsters created by the Lost Heart Company from the loose memories that roam Mnemosyne. They may be created from an unlimited amount of a single person's memories, and the emotional poignancy of the memories determine the Frangere's strength. Once defeated, the memory or memories that a Frangere is made up of are returned to their host, forcing them to come to terms with them. A person with a rampant Frangere in Mnemosyne will fall into a state where they are incapable of recalling or forming memories— a condition which has been dubbed by medical professionals as a Hypermnemonic Lapse.
  • Elpis (エルピス Erupisu?) - A beast living in the depths of Mnemosyne. The origin of all thought, according to the Demiurge.
  • Ennoia (エンノイア En'noia?) - A beast living in the depths of Lethe. Its nature is unknown.

Fractal Beings

  • Xénos (ゼノス Zenosu?) - An artificial fractal being created by Argand. It takes on the physical appearance of Mandelbrot, much to his chagrin.
    • CV: Saito Soma / Joe Zieja
  • Monad (モナド Monado?) / The Absolute (絶対 Zettai?) - The supreme fractal being who is responsible for creating the greater universe and all other fractal beings.
  • Achamoth (アカモス Akamosu?) - A high ranking fractal being who has disappeared along with Demiurge.
  • Demiurge (デミアージ Demiāji?) - A high ranking fractal being who fell out of grace with Monad by creating the material universe and a finite reality.
    • CV: Kousuke Toriumi / Mark P. Whitten

    • Fukuraku Fine Arts Academy (福楽美術院 Fukuraku Bijutsu-in?)
  • Mnemosyne (ネモシン Nemoshin?) - The river of memory. A realm that exists parallel to reality. It is directly tied to society's collective memories and current perceptions of the universe, and thus looks virtually indistinguishable from the real world. That being said, the appearance of Mnemosyne shifts based on any changes in how people view/remember the world. Although Mnemosyne can be entered by anyone from Lost River and the cures, it cannot be accessed by normal civilians, and each person is represented in Mnemosyne by their loose (lost or repressed) memories that travel around in real time alongside their counterparts in reality.
  • Lost River (ロストリバー Rosuto Ribā?) - A realm that exists parallel to reality. Since being overthrown by the Lost Heart Company, Lost River has gone into stasis.

    • Lethe (レーテ Rēte?) - The river of oblivion. The actual river beneath Lost River. Anything that falls into the river's mist is permanently forgotten.
  • The Fractal Realm' (フラクタル次元 Furakutaru jigen?) / 'Pleroma (プレローマ Purerōma?)

Other Media

  • Planned Memoria Pretty Cure Movie (Title TBA) - The team reunites a year after the series' end to tie up loose ends caused by Argand and the Fractal Beings. With Commeo, the new chairman of the Ministry of Research, acting as their guide, the Cures and Soreía must traverse Lethe and piece together the missing pieces of Lost River's greatest puzzle-- the true nature of the forgotten river's mist, and the terrors that lie downstream.


  • All members of the Lost Heart Company are named after common Escape-Time fractals (Lyapunov fractals, Julia sets, Burning Ship fractals [or rather one of its creators, Otto Rössler], the Tricorn or Mandelbar set, Newton fractals, and the Mandelbrot set).
    • Argand is the sole exception to this, as she is instead named after the complex plane (or Argand plane) that Escape-Time fractals are plotted on.
    • Two other characters from Lost River bear names of similar origin; Manowar is named after the Manowar fractal, and Descartes is named after René Descartes. He invented the standard Cartesian plane, which the Argand plane modifies.
  • Other residents of Lost River have names centred around time and memories.
    • Rythmo comes from the Greek word for rhythm.
    • Commeo's name is a Latin word that means back and forth, in reference to pendular movement in a grandfather clock.
    • Commeo's assistants, Retra and Antero, are named for the two primary types of amnesia: retrograde and anterograde.
    • Tokiba's name is derived from the Japanese word for time.
  • The city of Fuhendama is largely based on Sendai, Miyagi.
    • The names of Fuhendama's five wards (which are themselves based on Sendai's five wards) all contain characters for different measurements of time:
      • Jichuu contains 時 (ji?), meaning hour.
      • Hiyanagi contains 日 (hi?), meaning day.
      • Toshikara contains 年 (toshi?), meaning year.
      • Noshinai contains 代 (dai?), meaning decade or era.
      • Yonoue contains 世 (yo?), meaning generation.
  • Memoria Pretty Cure takes place during the Japanese 2019-2020 school year.
