     From the Real World 

The Priestess of Byakko: Suzuno Osugi

The heroine who continued the story of The Universe of the Four Gods after Takiko Okuda. Suzuno was a playmate of Takiko ever since she had memories, and adores Takiko as her big sister figure. At the beginning of this story, she was confused as to why Takiko was suddenly "married off" as explained by her father, and disappeared from her life without giving her a proper farewell... Suzuno was absorbed into the The Universe of the Four Gods by the instruction of her father to escape The Great Kanto Earthquake of 1923, only 2 months after Takiko.

Post earthquake, she became the foster daughter of Dr. Oikawa with three additional foster brothers, Seiji, Kenichi, and Hidero.

  • Affectionate Nickname: “Suzu.” The few loved ones who calls her by this name were her parents, Seiji, and Hidero.
  • Ascended Extra: Suzuno was briefly featured in the original Fushigi Yuugi, Fushigi Yuugi: Genbu Kaiden and the Byakko Ibun prequel. Here, however, she is slated to be the main character.
  • Beauty Mark: One near her mouth, which may be related to the Japanese belief that people with moles on their faces will lead tragic lives.
  • Break the Cutie: The first chapter of Byakko Senki sees her arriving to the world of book as a little girl, right after her life took a terrible turn thanks to the Great Kanto Earthquake that destroyed Tokyo and almost surely killed her parents.
  • Daddy's Girl: Unlike Miaka (whose dad left the family), Yui (hers is barely seen) and Takiko (whose relationship with her dad was quite complicated), Suzuno adores and idolizes her dad. It certainly helps that she's much younger and innocent than the other Mikos at the start of her journey.
  • Doing Research: Being aware that she has Trauma-Induced Amnesia, Suzuno would constantly survey her school's library for new in-coming books to see if any titles would remind her of the book she lost, which was The Universe of the Four Gods. Then one day came in a title named Faith and The Four Gods written by Einosuke Okuda, which led Suzuno into learning Einosuke Okuda being the full name of her "Honorary Uncle Okuda," along with the key term—"The Four Gods." And so went forth into researching the back number newspapers regarding the tragedy of The Okudas; which led to the revelation of her father's involvement, and her being "the next targeted priestess."
  • Drama Queen: Being a super sensitive little girl who probably soaked in too much Melodrama, she's prone to crying and dons out dramatic speeches for 3 days and nights if she doesn't get her way with her parents... Until the Great Kanto Earthquake messes her up for real.
  • Eccentric Artist: Post time-skip, Suzuno dives into drawing and painting as a therapeutic way to combat her Post-Traumatic Stress Disorder from the earthquake, and became a really talented artist. But all peers around her wearied her blank-state doziness is pushing her further in becoming anti-social.
  • Girlish Pigtails: Braided ones, both as the little girl from Genbu Kaiden and the very start of Byakko Senki and as the teenager she is in Byakko Ibun/Senki.
  • Hair of Gold, Heart of Gold: While the original FY depicted her as a brunette, the most recent artwork makes her hair closer to blonde. Probably to invoke this trope.
  • Ill Girl: She was diagnosed with PTSD after the earthquake, and caught additional Trauma-Induced Amnesia regarding the The Universe of the Four Gods. Whenever she attempts to search for memories, her brain shuts on her; giving her painful headaches, tremors, anxiety, and fever. Oikawa would always ask her to be tucked in bed to rest, and give her a dose of anxiolytic to calm her down.
  • Kid Hero: Due to Wham Episode effect, Suzuno is the youngest of all four heroines to enter The Universe of the Four Gods at the age of 8.
    • Ironically, she will become the eldest of all four heroines to face the full journey of the book at the age of 18.
  • Kid Hero All Grown-Up: Played with. The story of Byakko Senki happens only 2 months after the end of Genbu Kaiden. And was eventually aged-on by chapter 4.
  • Lethal Chef: Ironically, despite being willing to do kitchen work, and getting encouragement from Oikawa, she does not know how to use a knife well, and tends to burn up all of her foods. And being extremely sensitive in people's opinions on her, she withdraws from cooking altogether.
  • Meganekko: She became one post time-skip.
  • Trauma-Induced Amnesia: The PTSD that she caught from the earthquake and her first entrance into the book led her to have about 99% of amnesia regarding her experience from the book. As she ages, she's shown to only have fragments of images, with her slowly forgetting the names of people she encountered there. The only way she could do to preserve those memories was to jot the images down on paper as accurately as she could, and was seen confused with everything she's drawn.
  • Sailor Fuku: Since she's a school-aged girl from the Showa Era, aka the time when seifuku was implemented as a school uniform, she wears a dark blue one plus dark tights and black loafers.
  • Tragic Keepsake: Aside of the Universe... (in a way), she has Takao's pocket watch and Tamayo's best kimono.
  • Yamato Nadeshiko: She was said to be one in the original series.

An acquaintance of the Okuda and Osugi families. He is a doctor based in Tokyo whom for a period, treated Takiko's mother. During the first few days after the Great Kanto Earthquake, he goes around aiding people who were in need; eventually, taking in Seiji, Suzuno, Kenichi, and Hidero, who became orphans from the event, as his foster children. Post time-skip, Oikawa is an established doctor who runs his own hospital, and lives with his children within the facility.

  • The Bus Came Back: He first appeared as Takiko's Romantic Runner-Up in Genbu Kaiden. He returns in Byakko Senki alive and well, aiding Suzuno in the aftermath of the 1923 Great Kanto Earthquake.
  • Celibate Hero: Through Seiji's drunk blunder, all of his foster siblings, including Suzuno, knows that Oikawa has a lost Lenore and plans to remain single for his entire life. Much to his embarrassment. But as to who this "Lenore" was, Oikawa never revealed her identity to the children, so not even Suzuno knew it was actually her beloved sister figure, Takiko.
  • His Heart Will Go On: Upon Takiko's rejection of his hand in marriage, along with her death days later, Oikawa vows to remain single and never marry as Takiko is the only woman he loves, and will continue to remember her for as long as he lives.
  • Hospital Hottie: When he comes back to action and aged into his 30s, he's become more charming, yet with his ingenue cuteness intact.
  • The Ingenue: A notable male example. We all knew he was The Cutie ten years prior, but to see him being oblivious to Seiji’s romantic interest in Suzuno where even the youngest boys in the room noticed for years was just too hilarious not to swallow.
    • He’s also noted to be slow to anger to a fault. Suzuno wondered how he manages to stick with his happy face in the mist of all the chaos he has to endure in his hospital for a full year straight.
  • Like a Son to Me: He makes it clear to his kids that he loves them like his own children. But he holds Suzuno exceptionally dear to him due to his close relations with the Okuda and Osugi families.
  • Megane: Of the Meganekko type.
  • New Parent Nomenclature Problem: The children settled in calling Oikawa as, "Doctor." Or more accurately based on the original text, "Teacher;" which is a more affectionate title compared to "doctor" in most East-Asian culture.
  • Parental Substitute: To Seiji, Suzuno, Kenichi, and Hidero. Knowing that all of the kids knew they were orphaned, Oikawa treats them more on equal terms. But he doesn't hide his expression of love for them like his own, one bit.
  • Secret Keeper: Oikawa did not open the letter that was written by Einosuke Okuda to Takao Osugi during the aftermath of the earthquake. It was until Suzuno opened it up and researched herself that she rushed to Oikawa in letting him in on the "truth" to Takiko and Einosuke's tragedy and Suzuno herself being "targeted" by The Universe of the Four Gods.

Seiji Horie
Click to see him pre-time skip. 

An orphaned boy who's seen accompanying Oikawa in aiding Suzuno at the end of chapter 3, and became Oikawa's eldest foster son after the earthquake. Post time-skip, Seiji enrolled himself into military school inspired to be a militant in order to earn more income for his family, and grab better chances to search for The Universe of the Four Gods as per Suzuno's request.

  • Big Brother Hero: Seiji is the gender-flipped version of the intended trope, as Seiji is a protective, sexy older-brother figure who wants Suzuno to treat him as a love interest rather than a brother.
  • Big Brother Instinct / The Caretaker: He's a man who's willing to take on responsibilities for his new family, and especially for Suzuno.
    • This care-taking gesture for Suzuno grew on him into falling in love for Suzuno.
  • Big Damn Heroes: When Suzuno was almost kidnapped by human-traffickers, Seiji realizes this and quickly intervenes, telling the mean adults that he's talked to the police and they're on their way.
  • Career-Ending Injury: He fell from his horse during class, leaving his left foot critically damaged, which costs him his career plan on being a militant. Which will also in turn, prevent him from entering the front lines of the upcoming World War II in their near future.
  • Doing Research: One of the main reasons why Seiji enrolled himself into the military was to help Suzuno track down the book she lost, which Seiji speculated to be "Chinese related." But due to their nation's conflict with China, all materials related to China has been censored in Japan; and is only by joining the army that he can access grander materials related to China.
  • Hotblooded: Seiji holds the most compassionate personality of the boys, and is willing to move heaven and earth for Suzuno.
  • The "I Love You" Stigma: Upon having his foot broken, and noticed Suzuno has sketched some good-looking guy in her sketchbook, fearing she's gonna be swept away by someone other than him, he straight-out releases his Love Confession to Suzuno, and asked Oikawa for Suzuno's hand in marriage immediately after; which shocked the soul out of Suzuno, since she always treated him like a real brother.
  • He's All Grown Up: Just as Seiji was introduced as a young boy in chapter 3, the audience were immediately taken into time-skip the following next chapter. And man oh man how he hunked up!
  • Hunk: Manly attitude? Check. Manly responsibility? Check. One Head Taller than Suzuno? Double Check. A hot ripped body from military training? Triple. Check!
  • Number Two: In a sense, he's this to Oikawa. As an older boy (probably around Kasaru's age), he helps the good doctor to save people and especially younger children in danger after the Kanto Earthquake.
  • Rescue Introduction: We were introduced to Seiji as boy who performed a Big Damn Heroes moment to Suzuno, Kenichi, and Hidero. Solidifying his heroic personality.


The elder of the two boys who was saved from human-traffickers by Seiji's intervention alongside Suzuno. He became the 3rd foster child of Oikawa, and is shown to have talents in cooking.

  • Red Oni, Blue Oni: The red to Hidero's blue. But is a lot more chill-headed compared to Seiji.
  • Shipper on Deck: He roots for Seiji marrying Suzuno, and will make opportunities to let Seiji have some alone time with Suzuno. He’s also the boy who tries to hint Oikawa in considering to arrange said marriage for the pair, only to realize Oikawa was oblivious to the whole thing.
  • Team Chef: Normally, the girls in the family are usually the ones doing the cooking as per Japanese tradition, but Kenichi takes it on to himself to be his new family's cook, due to Suzuno being a Lethal Chef.


The younger of the two boys who was saved from human-traffickers by Seiji's intervention alongside Suzuno. He became the youngest foster son of Oikawa, and is shown to be gifted in medicine; Hidero is implied to often help around in Oikawa's hospital outside of school.

  • Like Father, Like Son: Suzuno commented to Oikawa on how Hidero is looking, and acting more like him despite not being his biological son.
  • Megane: As a teenager, Hidero, even though he's nice and thoughtful, is shown to be growing more towards the Stoic Spectacles realm as compared to Oikawa's cute ingenue personality.
  • Red Oni, Blue Oni: The blue to Kenichi's red.
  • Shipper on Deck: On the same page with Kenichi, Hidero too, also supports Seiji in marrying Suzuno, and will also create opportunities to let Seiji have some alone time with Suzuno.

Takao Osugi

Suzuno's father. Takao was a former literature student, assisstant, and good friend of Einosuke Okuda's family. Takao was entrusted in safekeeping The Universe of the Four Gods by the will of Einosuke.

As the Great Kanto Earthquake of 1923 struck, Takao survived the initial wave, but was unable to escape his collapsing house, which was on fire. In order to let Suzuno survive, he orders Suzuno to open The Universe of the Four Gods for the book to send her to safety. Takao was then left to slowly wither away from the lack of oxygen.

  • Berserk Button: Stating any bad opinions about his beloved teacher, Einosuke Okuda, and the Okuda family in general will bring out the mad dog in him. Doubled if it’s about the deaths of Einosuke and Takiko.
  • Cannot Spit It Out: With all the question dumping from his daughter regarding Takiko's disappearance, Takao just can't do it. However, he informs her that Takiko "lives within 'the book.'"
  • Good Parents: He and Tamayo clearly love their daughter and made sure to let her know that.
  • Papa Wolf: If Suzuno is in danger, there's nothing he wouldn't do for her. He spends what's all but stated to be his last moments sending Takiko to the Universe for protection, and telling her that he and Tamayo love her.
  • Secret Keeper: Of the terrible truth behind the Universe of the Four Gods and Takiko and Einosuke's cruel destiny.

Tamayo Osugi

Suzuno's beloved mother, and wife of Takao. Tamayo died in the Great Kanto Earthquake as their home collapsed onto her.

  • Good Parents: Loves Suzuno as much as Takao does, and Suzuno loves her lots too.
  • House Wife: She's always seen doing her best to mantain the Osugi house, plus she's stated to be a Supreme Chef. In fact, she was inside the kitchen and making lunch when the Kanto Earthquake happened, and her hand is seen sticking out from the rubble - signalling her death.
  • Secret Keeper: She's the only one aside of Takao who knows what truly happened to the Okuda family.
  • Yamato Nadeshiko: She has all the marks: she's cute but not a bombshell, has dark hair, wears kimonos, etc.

Einosuke Okuda

A scholar in Chinese Literature and the Japanese translator of the ancient Chinese scroll—The Universe of the Four Gods. His daughter fell victim of the The Universe of the Four Gods, therefore, he entrusted his student Takao to dispose the book.

  • Foregone Conclusion: He and Takiko have been dead for at least two months at the beginning of Byakko Senki.
  • Honorary Uncle: He seems to have been considered as such by Takao's wife and daughter, with Suzuno calling him "Okuda-ojisama" ("Uncle Okuda", with the "-ojisama" being the most polite and respectful pronoun for an older man)

Takiko Okuda

Daughter of Einosuke Okuda. She was absorbed into The Universe of the Four Gods and became "The Priestess of Genbu" within the book.

  • Foregone Conclusion: At the start of Byakko Senki, she has already been dead for at least two months after fulfilling her "Priestess of Genbu" duty at the cost of her life.
  • The Lost Lenore: For Oikawa.
  • Onee-sama: Suzuno looked up to Takiko and really wanted her as her big sister figure, referring to her as "Taki-neesama" ("Big Sister Taki", also in its most respectful tone).

     The Seven Celestial Warriors of Byakko 


Important Notice: Due to Watase's manipulation, as of the first chapters, the identity of "Tatara" is by far not revealed. As the story unfolds, readers should expect mass changes along the way.
Known to be named as "Kasaru Tsuonie." Tatara is a known survivor of the Byakko saga.

The identity of Tatara as of current development, is speculated to be one of the Raotsue Brothers—either the elder, Kasaru Raotsue, or the younger, Karumu Raotsue; both of whom encountered Suzuno as they traveled through the "Desert of Death" located north of Sairou.

His Celestial Mark is the Chinese character for "Bond" located on the top of his right hand.

Tropes known for Tatara as per Fushigi Yuugi

Tropes under Kasaru Raotsue

Click here to see Kasaru. Spoilers beware. 

A gentle, soft-spoken, and vocally-reserved young man. He takes Suzuno under his care upon his encounter with her while traveling through the desert with his little brother, Karumu.

Tropes for Karumu Raotsue

Click here to see Karumu. Spoilers beware. 

The younger brother of Kasaru Raotsue, contrasting to his brother's personality, Karumu is just as kind but far more openly opinionated. He befriends Suzuno upon his encounter with her while traveling through the desert with Kasaru.


Born Lanva (Ranva) Ham. Tokaki is the future husband of Subaru, and known survivor of the Byakko saga.

His Celestial Mark is the Chinese character for "Legs". Oddly enough, the mark is located his left cheek.


Born Dorin. Subaru is the future wife of Tokaki, and known survivor of the Byakko saga.

Her Celestial Mark is the Chinese character for "Hairy Head". Also odd enough, her mark is located on her upper left breast.

  • Action Girl: One that is also seen fighting when she's in her century of age in the first series.
  • Ascended Extra: With Tatara and Tokaki from Fushigi Yuugi.
  • Battle Couple: She is both Tokaki's wife and partner, for reasons that no one understands.
  • Time Master: Her Byakko-given powers, which by the time the original series takes place are so great that they let her place a decades-long time-reversing spell on Tatara (on the condition that he doesn't step out of a determined place, lest the magic will automatically wear off) and temporarily revert herself and Tokaki to their physical prime so they can fight the Seiryuu Senshi.





     The Sairou Royal Empire 

Emperor Nahito

The young and recently enthroned Emperor of Sairou, who seems to have LOTS on his plate already.

  • The Beautiful Elite: He's a gorgeous young man in a very high position of power.
  • Dumb Struck: His mind went on a 3-minute breakdown (or to put it more professionally, “high speed process”) when the Hoshiyomiko priestesses reported that the Byakko Priestess has descended to their nation.
  • The Emperor: Subverted in that he had just been enthroned as Emperor. So he's the royal house equivalent of an Ensign Newbie already in need to deal with a full table of crisis: 1) Bandits roaming the nation, 2) a cult religion, and the bombshell of 3) The arrival of The Priestess of Byakko. Sheesh.
  • Immortality Seeker: He's rumored to be this. Neiran was captured and attempted to be send as a coronation gift to him by the public because of its widely rumored saying that "anyone who eats the liver of a 'fuuin' (such as her race) will be granted immortality." It is also implied that Nahito is desperately researching different ways to disband "The Sanga" due to the group forming a separate religion away from their national god—Byakko.

The Hoshiyomiko

An all-female group of oracles who read the stars and constellations to make their predictions.

  • Facial Markings: Three of them are seen, and they all have big marks on their foreheads.
  • No Name Given: "Hoshiyomiko" is more of a title than a name.
  • Miko: They're highly-respected oracles and priestesses who reads the will of the stars.

     The Sanga (Great Monk Alliance) 

The Great Priest

The biggest rival to Emperor Nahito and leader of what seems to be a dangerous religious cult in Sairou.

  • He Who Must Not Be Seen: In his first apparition, only the lower part of his face is shown to the readers.
  • Meaningful Name: Sort-of: The kanji Watase used for "Great Priest" actually means "Pope". Given the setting, however, it seems to be more akin to "Lama" or "Buddhist High Priest" (or its FY-world equivalent).
  • Sinister Minister: He and his followers are a powerful group of monks who oppose the authority of Emperor Nahito.



Byakko the God


One of the two protagonists of Fushigi Yuugi: Byakko Ibun, she returns in Byakko Senki as a young adult.

  • Action Girl: A beautiful young woman who saves the newly arrived and very traumatised Suzuno, by using her Tiger form on bandits that were about to attack the two of them.
  • Big Eater: When she wakes up after saving Suzuno from the bandits, she pretty much eats all the food that Kasaru and Karumu had handy with next to no manners. It's rather understandable: she had been kidnapped, locked up in a cage, and probably not feed well (if at all) during her captivity; plus she's a woman with shapeshifting powers and a very physical fighting style, meaning that she genuinely needs more food than average.
  • Broken Bird: From what it's been shown in the first chapters, neither the terrible Break the Cutie process she went through during Byakko Ibun, nor whatever happened to her through her Time Skip hasn’t done her any favors. Kasaru states that she has severe rage issues and even more severe self-hate.
  • Damsel out of Distress: She had been captured in her Tiger form and about to be taken to a local noble strongly implied to be Emperor Nahito, when the caravan that caught her was attacked. As soon as she could, she released herself and killed said bandits.
  • Don't You Dare Pity Me!: This is her biggest Berserk Button. She reacts so badly to anyone expressing compassion for her (since she sees it as them being condescending), she will attack them on sight. Sometimes, this will include her morphing into her Tiger form.
  • Fake King: When the Sairou soldiers find her and mistake her for the Priestess of Byakko, Neiran, by wearing the kimono of Suzuno's mother, and using the compass charm she snatched from Suzuno, pretends that she is the priestess and decides to usurp Suzuno's spot as such from then on. She does this because she has had so few happiness in her early life as the "cursed child" Reipin that she wants people to bow to her and respect her.
  • Green-Eyed Monster: She's gone through such hard times that she deeply hates anyone who's had a better deal than her: Karumu and Kasaru had one another, Suzuno had her kindly parents, etc. This gets so bad at some point that upon realizing that Suzuno is the Priestess of Byakko, she seriously considers killing her out of jealousy over how good Suzuno's life has been until then, though she's foiled as Suzuno's body emits a Pillar of Light coming from her Priestess condition — and she's sent back to Tokyo.
  • I Am a Monster: The person she loathes the most is her own self, and she believes herself to be this:
    "Helping a monster like me will only end in disaster!"
  • Kick the Dog: Attacking Suzuno out of jealousy when they're both alone, plus taking her spot as the Priestess of Byakko when she disappears.
  • Only Friend: She hates pretty much anyone in her surroundings... save for one single person who, as she explains to Kasaru, "truly understood me". This person's name isn't mentioned, but it's a sure thing that it's Nirusha aka Miboshi.
  • Pet the Dog: After realizing who the clothes she had been wearing belong to, she gruffly tells Suzuno that she'll give them back to her as soon as she can.
    • Even after she has an angry breakdown due to Kasaru confronting her, she saves Suzuno from falling into a pit. Especially noticable since she does it by reflex. But later she pulls what has been described in "Kick the Dog"...
  • Silly Rabbit, Idealism Is for Kids!: She used to believe strongly in the legend of the Byakko Priestess and her Senshi, but now she scoffs at it and at the more innocent Suzuno.
  • She Is All Grown Up: She was a little girl in Byakko Ibun, and returns as a young adult by Byakko Senki.
  • Rescue Sex: Subverted. She tried to offer this to Kasaru as thanks for saving her and Suzuno (and probably to shut him up since he had been asking too many questions), but Kasaru immediately refuses and tells her that he can see her surrounded by the spirits of the people she has devoured. Neiran doesn't take it well.
  • Took a Level in Cynic: Several levels, by the time she reappears.
  • Tragic Keepsake: She still carries the pendant that belonged to her tiger Missing Mom and helps her turn into her tiger form.
  • Used to Be a Sweet Kid: The Neiran from Byakko Ibun was a sweet little girl who did her best to keep herself sane in an extremely hostile environment. The one from Byakko Senki is a far more cynical and harsh Broken Bird who doesn't believe in almost anything any longer and is rather rude to her companions, even Suzuno. To be fair it'd be weirder if she stayed cute and happy after all the horrifying shit that happened to her, plus she's a bit more pensive when Suzuno tells her and the Raotsue brothers how she arrived to the World of the Book and realized that the kimono she's wearing belongs to Suzuno's Missing Mom Tamayo.
