The first OneeChanbara title, THE OneeChanbara. On the cover is Aya, the central protagonist of the series.

OneeChanbara or Onee Chanbara or Onechanbara (お姉チャンバラ OnēChanbara?) is a series of hack-and-slash video games themed around zombie outbreaks and beautiful women wielding Japanese swords. Developed by Tamsoft and published by D3 Publisher, the series started out in 2004 for the PlayStation 2 as part of D3 Publisher's Simple 2000 budget series. It has since then become a full-fledged franchise with its many titles ported to Xbox 360, Nintendo Wii, PlayStation Portable, PlayStation 3, PlayStation 4, and PC via Steam, as well as the production of two movies based on the series. The name OneeChanbara is a portmanteau of the Japanese words Onee-chan? (お姉ちゃん), which translates to "big sister" or "young lady," and Chanbara? (チャンバラ) which derives from an onomatopoeic word meaning "sword fight."

Often advertised by D3 Publisher as "sexy and grotesque sword fighting action," the OneeChanbara series is iconic for its bloody and gory hack-and-slash gameplay and for the fact that the main character of the series, Aya, battles zombies in her trademark fashion sense of wearing a cowboy hat, a fluffy scarf, and a bikini. Since the first title, Aya has been joined by other playable sword-wielding beauties throughout her various zombie-slaying adventures.

The latest title in the series is OneeChanbara ORIGIN, a remake of the first two games in the series that commemorates its 15th anniversary by featuring full HD, optimized storytelling, modernized hack-and-slash gameplay, and a new art style reminiscent of Japanese animation.


Premise[]

Zombies, the most common enemy type in the OneeChanbara series.

The OneeChanbara series mainly follows the central protagonist Aya, a beautiful master of the sword and an Undead hunter. She is partnered with her half-sister and deuteragonist Saki, who was the instigator of the first zombie incident before joining her sister in the zombie-hunting business. The half-sisters are members of the Baneful Bloodline, a powerful ancestry whose descendants are blessed with physical conditioning beyond peak human standards yet cursed with the potential fate of losing their sanity. While fighting the urge to lose themselves, Aya and Saki have participated in several zombie incidents throughout the series, slaying zombies and battling the instigators of each incident, each of whom are in some way or another after their Baneful blood. The Baneful sisters have been aided by Zombie Punitive Force (Z.P.F.) soldier Anna and later Vampiric sisters Kagura and Saaya.

Gameplay[]

NOTE: This section explains the gameplay and mechanics of the OneeChanbara series in a general sense (unless specified otherwise). Certain titles such as Onechanbara Z2: Chaos and OneeChanbara ORIGIN make alterations to staple mechanics such as Ecstasy Combination and the Berserk and Xtatic Forms.


The OneeChanbara series features hack-and-slash gameplay that puts players in control of the lone Japanese sword-wielding maiden Aya (or in later entries after the first title, a tag team of two characters) against a legion of undead. As a pure action series with few adventure elements (like puzzle-solving and exploration), most of its entries will see the player navigate through several small, arcade-style stages, completing objectives (such as finding a key and unlocking a door with it or clearing a room of enemies) to advance to the next area in a stage. When the player reaches certain areas in a stage, their path will be blocked by spiked gates (or transparently colored barriers in ORIGIN), indicating to the player that they must clear the area of zombies and/or other enemy types, sometimes spawning multiple waves of enemies, before proceeding. Sometimes right before the end of a stage, a boss battle will occur. Most boss battles are typical high health, high damage, smarter AI type affairs, encouraging smarter play. Upon the defeat of enemies and bosses, Yellow Orbs that serve as experience points to level up and strengthen characters (and in recent entries, currency for the in-game shop) will appear. These orbs are totaled after the completion of the current stage, leading to level-ups that grant points that allow the player to allocate these points to a handful of skills such as Vitality, Power, and Reach. In recent entries, the player is also graded for their combat performance during a stage, with the highest rank being "V" rank (which stands for Violent). The higher the rank that is achieved, the more Yellow Orbs (currency) that are earned.

Depending on the game, the player has access to after story challenges such as a gauntlet mode that features an infinite number of floors against enemies and bosses (a good way to level up characters), and missions with specific objectives that players must fulfill to complete them. There are also "Quests" which are stage or mission objectives that players can complete by performing certain actions multiple times, such as performing Ecstasy Combinations many times or taking no damage against multiple bosses. Completing these Quests will unlock rewards such as artwork and Rings to be purchased at the shop.


Mechanics[]

Cool Combination

The OneeChanbara series's signature staple is the Cool Combination (or Cool Combo for short), a mechanic that sets the series apart from other hack-and-slash games. It is possible for the player to fight enemies and bosses by simply mashing the attacks buttons. However, if they time a button press just as the player character's attack would land on the enemy, the speed and power of the next attack will be increased. Depending on the game, this is visually represented by either a brief blurring of the screen or a blue light emitted from the player character's weapon. Mastery of this mechanic will see the player performing perfect Cool Combo sequences, leading to quicker kills on enemies and bosses and higher rankings at the end of the stage. In addition, the last, most powerful attack in a given combo cannot be performed unless the player performs a perfect Cool Combo sequence. Not only can Cool Combo attacks be chained together, but dodging and jumping during Cool Combos will change that dodge or jump into a Cool Dodge and Cool Jump respectively. These Cool variations of dodging and jumping are useful for maintaining the current Cool Combo sequence. Although not given a name, Quick Reload also has a Cool Combo variant.

Since the second title THE OneeChanbara 2, players have access to a practice mode where they can view the frame data of attacks and practice Cool Combo timing.

Splatter Gauge and Reload

The more the player attacks enemies (except statue and machine enemies), the more that bloodstains build up on the player character's body and, more importantly, the more the Splatter Gauge (represented by a sword on the bottom-left of the screen) is filled. The player's attacks will become slower the greater that the Splatter Gauge is filled, and in the first few titles, if the player attacks a zombie while the Splatter Gauge is at max, the sword will become lodged into the zombie, making the player stuck and vulnerable to enemy attacks. To keep the player character's weapon at tiptop shape and maintain maximum attack speed, the player need only press the Reload button to shake off all the blood on the weapon and completely empty the Splatter Gauge. If the player presses Reload during an attack, a quicker but less effective version called Quick Reload will be performed.

Stain Gauge and Rampage/Berserk Form

Similarly to the Splatter Gauge, the Stain Gauge, represented by either a bar or a circle on the bottom-left of the screen, will fill the more the player attacks enemies. The Splatter Gauge can also be filled via two more methods: by picking up Blood Crystals dropped by enemies, or by using a Blood Clot, obtained by ripping the heart out of a Mudman. Once the Stain Gauge is completely filed, the player character will enter a mode called Berserk Form which greatly increases the player's attack power at the cost of gradually draining health. In the first few titles, Berserk Form could not be ended without either dying, reaching a Goddess Statue, or completing the current stage. In later entries, Berserk Form will still drain health but the Stain Gauge will gradually decrease, eventually reaching zero and ending Berserk Form. Picking up Blood Crystals while in Berserk Form will replenish health, while using Blood Clots will have the same effect but greater. Berserk Form not only greatly increases attack power, but it allows players to dispose of Mudman zombies without the need of a special thrust combo.

To date, the only main player character who cannot enter Berserk Form is Anna since she does not have Baneful blood.

Character Switch

Players are given control of a tag team of two characters, chosen from several (sometimes a multitude of) sword-wielding women like Aya, each with their own unique play style. At any time during a stage, the player is able to freely swap between their two chosen characters. This mechanic not only leads to more varied gameplay, but it also allows the swapped out character to recover the grey (or blue) portion of their health bar if they previously sustained damage. It is also useful for temporarily halting the gradually draining health aspect of the Berserk (or Rampage) Form.

Predict

Introduced in Onechanbara: Bikini Samurai Squad. If the player dodges an enemy attack at the last second, the game will briefly enter slow-motion, indicating that a Predict was successfully performed, allowing the chance to perform a powerful counter attack.

In ORIGIN, counterattacks cannot be performed after a Predict, but doing Predicts will significantly fill the Ecstasy Gauge.

Weapon Switch

From Onechanbara: Bikini Samurai Squad onwards, most playable characters can switch between two weapon types. For example, Aya can switch between one katana and two katanas, Saki can switch between a tachi and knuckles, Reiko can switch between katana and guns, etc. Weapons can be switched during combos, making it possible to perform an infinite combo string.

Ecstasy Gauge and Ecstasy Combination

Introduced in Onechanbara: Bikini Samurai Squad, (with regard to entries before ORIGIN) the Ecstasy Gauge (represented as three bars at either the bottom-left or top-left of the screen) is filled by performing Cool Combos on enemies and bosses. At the expense of a single filled bar, the player can perform an Ecstasy Combination, a powerful move that each character has a unique version of. In the Onechanbara Z titles, Ecstasy Combinations increase in duration and power depending on how many bars were previously filled. Unlike the other gauges, the Ecstasy Gauge will gradually deplete at all times unless the player maintains the gauge with Cool Combos.

In ORIGIN, the Ecstasy Gauge and Ecstasy Combination are slightly renamed to "Xtasy Gauge" and "Xtasy Combination."

Xtasy and Dare Drive

Introduced in Onechanbara Z2: Chaos, Xtasy and Dare Drive are transformations boasting far greater attack power than Berserk Form in addition to sporting a bestial or demonic appearance. The Xtatic Form is a transformation exclusive to Aya and Saki while Dare Drive is exclusive to Kagura and Saaya.

The Xtatic Form was reintroduced in ORIGIN with overhauled mechanics.

Trivia[]

  • Given the Japanese origin of the series name OneeChanbara (お姉チャンバラ), it is not agreed upon as to the official way to write the title in English. For the series's first titles on the PS2, the series name was scrapped entirely for wholly English titles such as Zombie Zone and Zombie Hunters. The Xbox 360 title, Onechanbara: Bikini Samurai Squad, began the trend to spell the series as Onechanbara for over 10 years until the release of OneeChanbara ORIGIN. Even then, the latest OneeChanbara title has been written as either OneeChanbara ORIGIN or Onee Chanbara ORIGIN by public media outlets and online retailers.
  • During a D3 Publisher presentation at Tokyo Game Show 2018, D3 Publisher producer and series producer Nobuyuki Okajima and series lead director Shunsuke Tezuka came up on stage to speak about the newly revealed OneeChanbara ORIGIN while giving surprising and humorous details about the origin of the first OneeChanbara title.[1][2]
    • Okajima revealed that the title was originally going to be dubbed THE Nēchan (THEねーチャン), but the name changed to THE OneeChanbara because he wanted to add in a pun.[1][2]
    • Tezuka revealed that the main character of the first title was originally going to be Saki, while Aya would have been the final boss. Okajima added that they switched the roles because it was better that way.[1][2]
