OneChanbara Wiki

OneeChanbara ORIGIN or Onee Chanbara ORIGIN (お姉チャンバラORIGIN, OnēChanbara ORIGIN) is the latest entry in the OneeChanbara franchise, developed by Tamsoft and published by D3 Publisher. The game was originally released in Japan for the PlayStation 4 on December 5, 2019 and later in other Asian territories on September 24, 2020 and in North America and Europe on October 14, 2020. It was also released on Steam on October 14, 2020. English, Chinese, and Korean localizations were funded by Clouded Leopard Entertainment.

OneeChanbara ORIGIN is a remake and a retelling of THE OneeChanbara and THE OneeChanbara 2, the first two games in the OneeChanbara series. In order to commemorate the 15th anniversary of the long-running series, the visuals of the first two games have been brought into full HD and rendered in a beautiful new anime art style, courtesy of renowned character artist Katsumi Enami. The storytelling of the first two games has been optimized for a more cohesive and compelling tale about two estranged sisters locked in a deadly struggle. All will be revealed in this reinterpretation of the "origin story" that started it all.


OneeChanbara ORIGIN was first unveiled at Tokyo Game Show 2018 (TGS2018) on September 20, 2018, at D3 Publisher's booth. The game was revealed to be a remake of the first two OneeChanbara titles, THE OneeChanbara and THE OneeChanbara 2, meant to commemorate the 15th anniversary of the long-running zombie hack and slash series. Although no gameplay footage was shown, series producer Nobuyuki Okajima took the stage to present new character designs and 3D models of series main characters Aya and Saki, drawn by character artist Katsumi Enami. Also presented were screenshots of locales, such as flowery gardens and a hospital scene.[1]

The February 14, 2019 issue of Weekly Famitsu revealed the new character Lei, who would be voiced by Yū Kobayashi, as well as several screenshots detailing the vibrant, colorful visuals of Origin's new graphics engine. It also showed off the numerous Undead enemies Aya and Saki will face, including Undead bosses Devda and Anzu.[2]

On July 3, 2019, D3 Publisher released the first trailer for ORIGIN, showing video footage of gameplay for the first time as well as featuring the game's official theme song "Ai ha kimi no mono," performed by the metal idol unit Broken By The Scream.[3]

The September 12, 2019 issue of Weekly Famitsu revealed ORIGIN's Japanese release date to be December 5, 2019. The corresponding article also showed off Saki's new fighting styles and a new boss, Ubie.[4]

At Tokyo Game Show 2019 (TGS2019), producer Nobuyuki Okajima showed off extensive gameplay footage of ORIGIN during two separate livestreams for 4Gamer and local magazines Famitsu and Dengeki PlayStation respectively.[5]

On October 9, 2019, D3 Publisher released a second trailer for ORIGIN, including footage of Lei as a boss character.[6]

On November 21, 2019, D3 Publisher released the third and final trailer for ORIGIN before its official release date. In the trailer, the Japanese voice actresses of Aya, Saki, and Lei roleplayed as their respective characters and retraced the 15-years long history of the OneeChanbara series, making jokes about the series and about themselves, as well as introducing gameplay features and mechanics in the upcoming game.[7]

OneeChanbara ORIGIN was finally released in Japan for the PlayStation 4 on December 5, 2019. Less than a year later, ORIGIN was released in other Asian territories on September 24, 2019. Clouded Leopard Entertainment published this release as well as provided English, Chinese, and Korean localizations. Less than a month later on October 14, 2020, ORIGIN was released in North America and Europe for the PlayStation 4 and Steam.

Main article: OneeChanbara ORIGIN/Gameplay

OneeChanbara ORIGIN is a high-speed, stylish and violent hack and slash game featuring series staples such as Cool Combinations and character tag-switching, as well as new features such as Parry and Stun mechanics and reworked Berserk/Xtatic properties. The core combat flow of the game is a cross between pre-Z titles' simple and straightforward zombie-slaying mechanics and Z/Z2's free-form, Musou-esque (crowd-combat) combat system, with a hint of uniqueness from brand-new mechanics such as Parry/Stun and Cool Finish.

General Game Flow[]

The general game flow of ORIGIN is reminscent of oldschool arcade beat 'em up and hack and slash games, where the main objective was to clear a room of enemies to advance to the next. The settings that the player will encounter are essentially stage-based, with no backtracking possible and little incentive to explore, making ORIGIN a pure stage-based action game. The main story is chapter-based, each chapter serving as a separate stage. In each chapter, the main objectives to advance are either to clear a room of enemies or defeat a boss. Sometimes a single boss battle makes up the whole chapter. During enemy-clearing chapters, the player will often be blocked off by a transparent barrier that leads to the next room, forcing the player to first clear the room of enemies that subsequently appear; sometimes multiple waves of enemies will appear. Defeating enemies causes them to drop Yellow Orbs, which are used as both experience points towards leveling up the player characters as well as currency towards the game's shop. At the end of each chapter, the player will be graded on their combat performance based on criteria such as the number of Cool Combinations performed and time taken to complete the chapter. The highest grade the player can receive is a V-rank (for Violent). The player characters used during the chapter will also gain experience and level up from the Yellow Orbs gained from the chapter as well as from combat bonuses; upon level up, players can choose to increase one of three stats: Health, Attack, or Defense. After any chapter is cleared, the player is able to redo the chapter any time at the difficulty it was cleared at.

After the main story is completed, either on Normal or Hard difficulty, multiple features will be unlocked, such as the higher diffculties Beast and Berserk, and Bonus Missions such as Infinite Survival mode, which is very similar to the Devil May Cry series' Bloody Palace mode. If the player can clear 100 floors, they will unlock the third playable character Lei. There are also Quests, a series staple, which are basically objectives that the player may complete during either story mode or Bonus Missions to unlock extra content such as artwork, music, or Rings to be purchased at the shop.

Playable Characters[]

A swift swordfighter with excellent dodging ability, able to deftly switch between single-sword and dual-sword fighting styles. She is able to slay large numbers of enemies consistently. She is available from the start.
Her sword style is much slower than Aya's but her attacks are also much more powerful. She can switch to a fisticuffs style for faster attacks. Her dodging ability is not as effective as Aya's, but she has greater Stun and instant-kill potential. She is available from Chapter 13 onwards.
A swift and nimble combatant that is extremely agile with her combat knife. Her alternative weapon style is the use of multiple firearms. She cannot enter Berserk Form and Xtatic Form like Aya and Saki. Instead, she can enter a special state called Bloody Mode that will heighten the power and range of her bullets significantly. She is playable after unlocking her by either clearing 100 floors of Infinite Survival, or by purchasing the "Lei Instant Unlock" DLC.



In the year 20XX, in a dystopian version of modern-day Japan where zombies run rampant, there lived Aya and Saki, inheritors of the Baneful blood, and two half-sisters who lived apart from each other. They each lived with one parent: Aya lived with her biological father Oboro, who trained her hard everyday for years until she nearly became his equal in the way of the katana, while Saki was left behind with her biological mother and Aya's stepmother Tsubaki, her only source of emotional support. This split in the family lead Saki to resent her father and her older half-sister. However, two years before the events of OneeChanbara ORIGIN, Tsubaki was murdered. Devastated by the loss of his wife, Oboro disappears from Aya's life, leading Aya to use her swordsmanship to become a zombie hunter and leave home to search for her missing father and estranged half-sister.

One day, Aya came into contact with the informant Lei, who offered to help her find her family in exchange for taking on undead extermination tasks. For two years after leaving home, Aya traveled all over Japan, exterminating undead. Exhausted by the fruitless search for her missing family members, Aya was about to give up. That was until she received a text message from Saki...

In Japan, OneeChanbara ORIGIN fared well with Famitsu awarding the game a score of 32 out of 40 (8/8/8/8).[8]

In the West as of January 11, 2021, the PS4 version of the game currently holds a Metacritic score of 69 out of 100 based on 10 reviews, indicating mixed but generally favorable reviews.[9]


  • OneeChanbara ORIGIN was released in 2019 (in Japan) to celebrate the 15th anniversary of the series.
  • This is the second entry in the series to feature English voice acting, the first being Onechanbara Z2: Chaos.
    • It is also the first entry to feature Chinese and Korean voice acting.

OneeChanbara ORIGIN receives Famitsu's Gold Award.

  • This is the second title in the series to receive a 32 out of 40 on Famitsu, the first being Onechanbara Z: Kagura - With NoNoNo!. For recieving a score between 32 and 34 out of 40 on Famitsu, the title received Famitsu's Gold Award, in which the teams behind such an esteemed title are gifted with a decorated bottle of champagne.[10]
  • A first for the series, OneeChanbara ORIGIN features two theme songs instead of one:
    • "Ai wa Kimi no Mono" (アイハキミノモノ Love is Your Thing), performed by the metal idol group Broken By The Scream, and...
    • "Unbreakable Trust!!", composed by Akihi Motoyama and sung by Florence McNair with lyrics written by Ike Nelson.
  • The spacial and bodily positions of Aya, Saki, and Lei on the official box art of OneeChanbara ORIGIN pay homage to the box art of THE OneeChanbara 2.
  • In the third official Japanese trailer, there is an editing error where Aya's official render of her alternate costume is used to hide an erroneously placed render of her 3D model. It is even noticeable from the video's thumbnail.
  • From Chapter 13 onwards, Aya and Saki venture through the Asakusa district of Tokyo, visiting former tourist locales such as the commercial pathway to the Sensō-ji temple. Asakusa is also the location of OneeChanbara series developer Tamsoft's headquarters.[11]
  • In Chapter 13, it is revealed that Aya wrote for herself a self-introductory poem detailing her unparalleled sword skills and admitting that she is "kind of a weird" girl. During an in-game conversation between Aya and Saki, Saki humorously recites this poem, causing an embarrassed Aya to cut her off and interrogate her as to how she knows about it.[12] The first few lines of Aya's poem are a reference to her beginning monologue from the first OneeChanbara title, THE OneeChanbara. The same monologue was similarly made fun of by Lei in the third official Japanese trailer.
  • In Chapter 15, during an in-game conversation between Saki and Lei, Saki, annoyed by Lei's insistence in calling her "dear Saki" (咲ちゃん Saki-chan), snarkily gives Lei the nickname "Lei-of-Sunshine." In Japanese, Saki actually calls Lei レ・イ・子, which is written as Reiko in romaji.[13] Reiko is the name of the character that Lei is originally based on.
  • Oboro (during his Xtatic form) has an attack where he summons long, sword-like blades from his left sleeve to attack with like a claw. This "claw" is also seen in his official render. The claw is a reference to his original zombie design in THE OneeChanbara.
  • The main antagonist Eva is voiced by Yūko Kaida, the original voice actress of Aya since THE OneeChanbara 2.
  • (Spoilers for the final chapter. Expand to read.)
    The "ORIGIN" in OneeChanbara ORIGIN has a double meaning in that not only does it refer to the fact that the game is a remake of the first two OneeChanbara titles, it is also referenced in the final chapter when Lei, after having killed all her fellow clones and destroyed Uroboros, proclaims that she has become the "ORIGIN."
