Hakuoki

Like most otome games, the player takes the role of a female character who can choose from a variety of male characters as her 'love interest'.

Hakuoki's gameplay requires little interaction from the player as most of the game's duration is spent on reading the text that appears, representing either dialogue between the characters, narration, or the inner thoughts of the protagonist. Often, players will come be given the chance to choose from options displayed on the screen that would be crucial to the story. The time between these decision points is variable and during these times, gameplay pauses until a choice is made that furthers the plot in a specific direction. There are six main plot lines that the players will have the chance to experience, one for each of the heroes in the story. When interacting with the chosen heroes with the routes, an "affection meter" is created which is raised by giving them an answer that pleases them. The ending the player will get in each route depends on the affection the player has achieved.

It also included all the basic functions such as CG Gallery, Music List, Scene Recollection, and skip options. Once completing a route, player can unlock the ‘Record of Service’ to select exactly which chapter they would like to start the next play through on, as well as adjusting the bachelor's affection level to access the different endings. There's also encyclopaedia in understanding the historical terminology and timeline.

In the updated remake Kyoto Winds and Edo Blossoms, six more routes are added. In Edo Blossoms, there's also "corruption meter", which tells the players the bachelor's corruption rate after becoming a Fury. Making sure the corruption level is low is crucial to prevent the player from reaching bad ends.

Taking place during the Edo period, around the 1860s, Chizuru Yukimura heads to Kyoto to search for her father, finding herself attacked by mad men before they are cut down by members of the Shinsengumi who mistake her for a boy and take her into custody for interrogation. Upon learning that she is a girl and the daughter of a doctor who developed the Water of Life elixir that turns those that drink it into invincible blood lusting berserkers called Furies (羅刹, Rasetsu, lit. Rakshasa), the Shinsengumi decide to keep her as an aide in their search. In time, as the Shinsengumi aid the shogunate in the Bakufu, Chizuru begins to develop a bond with the Shinsengumi and its aloof member Toshizo Hijikata. However, as time passes, Chizuru and Shinsengumi confront a mysterious faction who claimed to be demons and that Chizuru is also a demon with her father revealed to be experimenting on the Water of Life to create the Furies to conquer the human race.

Unknown to Chizuru, her father under orders from the Shogunate develops the Water of Life (変若水, Ochimizu), an elixir that increases the drinker's healing abilities, speed, and strength yet could turn the drinker into a mindless killing monster called Fury. At the beginning of the story, she-(while disguised and mistaken for a young boy) is seen being chased by two men, who were suddenly attacked and killed by two Furies. She witnesses Saito and Okita kill off the Furies and is then taken to the Shinsengumi headquarters by Hijikata, where they allow her to stay, because they too were in search of her father. In the anime series, she eventually falls in love with Hijikata.

Chizuru has a secret: she is in fact a pureblood member of the demon clan, and the head of the demon of the East is of Yukimura descent, with Chizuru being the sole survivor of the clan by the end of the story. Because demons have scattered and declined in numbers over the centuries, especially the female ones, Chikage Kazama seeks her out to create a lineage of pure-blooded demons.

Similar to the original game, it consists of six routes of the same characters where Ibuki is required to make the right choice to form friendship with each main characters of their respective routes. In all routes, Ibuki always ends up leaving the Shinsengumi to start a new life of his own. Reaching the good ending of the routes would show the continuation of the ending of respective Shinsengumi members with Chizuru from the original game after war ends. Two updated versions of the game, Hakuoki: Reimeiroku Nagorigusa (薄桜鬼 黎明録 名残り草) and Hakuoki: Reimeiroku - Omouhase Kara (薄桜鬼 黎明録 思馳せ空), are released for PlayStation 3 on June 28, 2012, and PlayStation Vita on July 2, 2015, respectively.

Several spin-off were released not long after the original game, ranging from mini games to action RPG. The first spin-off, Hakuoki: Yuugiroku (薄桜鬼 遊戯録) is released for PlayStation Portable on August 26, 2010. Unlike the original game that requires the player to choose the right options to romance the chosen bachelor, Yuugiroku requires player to play mini games based on traditional Japanese games. A sequel, Hakuoki: Yuugiroku Ni – Matsuri Hayashi to Taishitachi (薄桜鬼 遊戯録弐 祭囃子と隊士達), is released on October 18, 2012, this time with the theme of games found on festival stalls.

Urakata Hakuoki (裏語 薄桜鬼) is released on June 27, 2013, for PlayStation Portable. The story is set in the same universe and timeline as the original game, but tells a non-canonical alternate story. The game focuses on Kozue Kirishima, who seeks out the Shinsengumi after her older brother was killed by a Shinsengumi member who became a Rasetsu. The game consisted of four different bachelor routes. Unlike the original game that requires little interactions, Urakata Hakuoki is an action RPG, in which the player plays as Kozue, moving her freely on Map Screen, exploring areas where she can get various items, and battling enemies. The game later received an updated version titled Urakata Hakuoki: Akatsuki no Shirabe (裏語 薄桜鬼～暁の調べ～) on August 7, 2014.

Hakuoki SSL: Sweet School Life (薄桜鬼 SSL), released for PlayStation Vita on March 27, 2014, unlike the other games, the story is set in modern times with Chizuru and the other characters from the original game introduced as students or teachers going to the same school.

Hakuoki received positive review. Metacritic gave the PSP version of the game the score of 79 based on 4 Critic reviews, which is a generally favorable review.^[15] The game is praised for its story-telling, character designs and development, and CG art. But has mixed review about the music and Kazama's route that is deemed too short compared to the other routes. The updated remake of the game, Kyoto Winds and Edo Blossoms also received positive review. Kyoto Winds is given the score of 83 from the same site based on 8 Critic reviews, once again praising the remake for its solid characters and story-telling.^[16] Edo Blossoms is given the score of 75, also from the same site, based on 9 Critic reviews, praising the inclusion of new characters that give fans new perceptive, but feels that the story's finale is not quite as interesting as its beginning. The decision to split the remake into two games also gained mixed review.^[17] Similarly, Hardcore Gamer praised the game for its story-telling, finding the focus of political and fantasy aspects in historical background is a different approach in otome game. The characters are also well-received, finding their struggle throughout the game relatable. The site also praised the inclusion of additional events and terminology highlighted during conversations for an easy glossary look up, though criticised the lack of interactive element within the game.^[18]

Theron Martin from Anime News Network give the first season a positive review. He praised the studio's way of properly integrating fantasy element into the actual history, the design of the male characters, and the music for using heavy, dark tones for its action and dramatic scenes, which "lends intensity and even an occasional amount of creepiness to the content." However, he criticised the plotlines about Chizuru looking for her father and the motivations of the various devils afoot in the setting are not handled properly due to the history portrayed in the series. He also criticised Chizuru's role as a heroine for following the typical reverse harem protagonist being damsel-in-distress that needs to be rescued.^[19]

THEM praised the well-executed art and the amount of depth and genuine drama in the story and the action scenes. The site also praised the studio for balancing Chizuru's character as being more dynamic than the standard female samurai era character tropes without anywhere near an idealized Mary Sue. The site finds the use of Rasetsu plot device repetitive, causing a lack of plot twists and surprise revelation in the series.^[20] The second season is praised for the characterization, while still finds the pacing and animation quality not balanced properly.^[21]
