Eiyuu Senki

Everything About Fiction You Never Wanted to Know.
The World Conquest

A man protects his village, and the village protects him. Sometimes he must put his life on the line. That is the duty of those who plants their root on the village

An H-game by tenco released March 30, 2012, Eiyuu Senki is most notable for starring a cast made up pretty much entirely of famous heroes and historical figures... turned into various bishoujo game heroines.

The gameplay overall is most reminiscent of the Rance series by Alicesoft, with a similar SRPG format as well as Loads and Loads of Characters, most of which you the protagonist can have sex with. Battles are done on a 3-square wide board, with your characters (up to six per battle) on the left and enemies on the right. The game is turn-based, both on the larger campaign map that shows all the various cities that can be conquered, as well as in individual battles. A few actions can be made per campaign turn, such as doing character missions, fighting battles and doing events; as the game progresses you can perform more actions per turn.

The characters are all improved through spending money (earned every turn on the campaign map and based on which cities you own) and through winning battles; characters who fight in a battle will receive a small amount of extra Power (which acts as both health and an indicator of overall strength), with an added amount if you complete a battle quickly and with few losses. Characters can also be improved through character interaction missions, which take up actions in each campaign turn but allow you to unlock additional abilities and attacks, more item slots, and of course sex scenes.

There are also items that can be applied to characters, acquired through missions and objectives as well as character interaction and story progression. Effects of these items range from increasing stats or decreasing the time between each of their turns.

The plot revolves around Himiko, a priestess that is trying to conquer Japan and hilariously failing. When it seems she and her troops will be killed by bandits after another embarrassing defeat, the protagonist comes out seemingly out of nowhere, defeat the bandits, but falls unconscious. Himiko takes his unconscious body to Yamatai, her hometown.

When the protagonist wakes up, he doesn't remember who he was but also completely confused at why the world is, well, the way it is: several of the world's heroes now live at the exact same time and despite being male in Real Life are female here, except for Himiko who was female anyway. He however, soon agrees to help Himiko in her attempt to Take Over the World, as she reveals she had a prophetic vision of darkness enveloping the world that can only be stopped by someone unifying it.

Published by Tenco and MAGES. GAME in Japanese and Fruitbat Factory and JAST USA and Kagura Games in English. It received a clean version without any H-scenes for both Playstation 3 and Playstation Vita in 2013 and 2014, respectively.

Tropes used in Eiyuu Senki include:
  • 100% Adoration Rating:
    • Everyone on Mongolia worships Kublai. She does treat very well and is constantly self-sacrificing, so that is not surprising.
    • Egypt is this to a fanatic level. Tutankhamon is basically a living goddess and any offense towards her leads to violent murder attempts.
  • A-Cup Angst
    • Himiko manifests constant inferiority when the hero meets women with significantly larger breasts than her.
    • Yoshitsune is actually pretty flat-chested. The protagonist accidently discovers that after her breast pad is injured, and she reveals how annoyed she is at that, not helping her family believes it's actually a curse of a rival clan.
  • Amnesiac Hero:
    • After saving Himiko on the opening, our hero collapses and when he wakes up, he barely remembers who he was.
    • Takeru lost her memory after gone missing for some time. She is aware of who she was, the king of Zipang, but she can't recall it.
  • Badass Teacher:
    • Sun Tzu, who wears a teacher hat and a stick but still goes to the frontlines.
    • Aristotle goes to battle first alone and after along with Alexander.
  • Big Eater: Lancelot eats really a lot and can hardly be caught discussing anything but what she ate recently, or what she wants to eat next.
  • Butch Lesbian: Himiko assumes Oda Nobunaga is one, much to her annoyance.
  • Clingy Jealous Girl: Himiko is clearly envious of Arthur being that clingy to the protagonist, having been already bedded and romanced by her.
  • Cloudcuckoolander: At least everyone acts like Arthur is one around her, but she is right mostly of the time, it's just that she reaches conclusions others can't seem logically.
  • Cute Clumsy Girl: Both Himiko and Tutankhamon struggle at doing anything right, but also are adorable.
  • Dead All Along: Himiko speculates that is why the Maharaja act so fiercely to protect Delhi of being conquered, because Ashoka is actually dead. The protagonist finds that unlikely.
  • Disaster Dominoes: Tutankhamon injuring herself while trying to grab Zipang's declaration of war leads to the whole Egypt think of Zipang as enemy because somehow was their fault, leading to them individually declaring war on the Japanese, leading to actual war. That without Tutankhamon lifting one finger because she blames herself for it.
  • Does Not Know Her Own Strength: Benkei used to do not, but Yoshitsune explains during one of Benkei's missions that she taught her how to properly use it.
  • Dumb Muscle:
    • Benkei is pretty strong, but it's so dumb she thinks Yoshitsune can be staying under a tree or a giant rock, and ends up pulling a tree by the roots.
    • Lu Bu is not that far way, constantly rushing into places without caring about collateral damage.
  • Final Boss Preview: Arthur's abilities are shown just after the Zipang arc ends, with she appearing with a HP and damage higher than even Takeru, and the Zipang characters advise the protagonist by saying she must absolutely be their last opponent, thanks to the fact her Knights of Round Table are the strongest warriors on the world. So at least in-universe what you just saw is a preview of the final boss.
  • Fish Out of Water: The protagonist has small, scattered memories of his past, but seems to come up from our world, having the same knowledge of history and therefore completely lost at why historical figures of different ages are all living at the same time, and despite most of them being male they're all girls.
  • Friendly Enemy: Despite Arthur establishing an alliance of Brittania with Zipang, the Zipang's characters do not give up on the plan of conquering the whole world, but accept Lancelot in their ranks as a gesture of friendship.
  • Full-Frontal Assault: Ashoka goes to war naked, with a little piece of cloth just doing the minimal job of hiding her genitals, breasts bare. It stands out even in a game full of Stripperific outfits.
  • Gameplay and Story Integration: The fact Egypt isn't actually at war with Zipang reflects in how they attack: they just rush giant number of weaker troops at you and rely on getting a game over by fifty turns because you can't kill them fast enough and may not regenerate enough troops to survive an attack on their enemy turns.
  • General Failure: Himiko had already lost most of her military resources offscreen before the story even begins, and then walks right into a obvious trap set by Nobunaga that she knew about but ignored it anyway.
  • Girlish Pigtails: Inverted with Yamato Takeru; she has a very deep voice and acts very manly despite having long purple pigtails.
  • Glass Cannon: Nobunaga does a lot of damage and has incredible long-range with her gun, but her defenses stats are awful and needs to be put in the back if you want her to survive most fights. Thankfully, in this game friendly fire by her is impossible, because otherwise she would be constantly firing on her own's allies back.
  • Hello, Insert Name Here: The protagonist is by default called Chihaya, but the player can rename him. Most characters simply call him "Servant of Heaven", as Himiko thinks he is.
  • Hoist by His Own Petard: Egyptians rely on getting a zero turns game over since their troops are weak and their spells make your troops weaker or slower, but once you get their cities, it means you can stall them too by getting a zero turns game over during defensive battles and make Himiko regenerate your troops while waiting the battle to end.
  • Hopeless Boss Fight: The first fight with Yamato Takeru. She has way more HP than any of your units and a one-hit kill attack thanks to its massive damage.
  • Hope Spot: Just when the party defeated Nobunaga, unified Zipang and Himiko has confessed and given her virginity to the hero, Takeru goes insane for no reason and begins to burn Yamatai.
  • Incompatible Orientation: Marco Polo definitely is into Kublai, but Kublai is straight and see her more as a dear friend and ally.
  • Innocent Fanservice Girl: Ashoka finds no problem in walking around bare-naked.
  • Interface Spoiler: Checking each city's income, you will easily notice Babel has the highest one. Just guess what is the city of that list will be the last to be conquered.
  • Ill Girl: The empress of China appears to be this. What is actually happening is she ingesting large quantities of mercury and poisoning herself, just like her real-life counterpart.
  • Lipstick Lesbian: Marco Polo is pretty feminine and gushes over Kublai again and again.
  • Locked Out of the Loop: Ashoka had no idea of how miserable India is or even that Zipang had declared war on her country, thanks to the deceitfulness of the Maharaja. Only once Delhi is taken over and so is its supply lines she became aware of the war.
  • Man Child: Alexander seems to be in her early twenties but have no idea what sex is and have vague ideas of how men and women love each other, to the embarrassment of the protagonist.
  • Mighty Glacier: Benkei is slow but does an comparatively absurd amount of damage once she can attack from a close distance with her fists. Her spear causes much less damage.
  • Mistaken Identity: Sanzouhoushi mistakes the protagonist for her sidekick Hakkai, who anyone well versed in Journey to the West knows is a pig-man. The protagonist is initially convinced by this because of his amnesia until it finally dawns on him off-screen what the Monkey Princess meant.
  • Motor Mouth:
    • Himiko doesn't shut up once she is provoked into talking over taking over the world. Takeru isn't amused and try to stop the protagonist of triggering it at the early parts of the game.
    • Sanzouhoushi don't stops once she starts talking. The subtitles eventually give up on her, and resume her babbling to yada yada yada.
  • Only the Chosen May Wield: Only the rightful heir to Zipang may wield the Kusanagi. It is Takeru's possession at the beginning of the game, but she gives it to the hero thanks to her deteriorating health.
  • Orcus on His Throne: Ashoka, despite being Queen of India, is said to not take an active role on administering it, making a higher priority for the party to take out her Maharaja, who actually rule over India.
  • Power At A Price: Implemented in gameplay. Conquering certain regions before others allows you to get certain items which increase your power, but the game balances it by upgrading all the other country's armies.
  • Playing with Fire: Yamato Takeru and the protagonist can manipulate the flames using the Kusanagi.
  • Retired Badass: Yamato used to be the strongest hero of Zipang, but decided to retire to Yamatai before the beginning of the game, much to the annoyance of Himiko, who wanted her talents used in battle.
  • Rousing Speech: Sanzouhoushi attempts one for the people of Delhi after the heroes conquer it. Attempts. What she does up causing is something that the protagonist describes more like mass mind control mixed with These Are Things Man Was Not Meant to Know, affecting even Himiko.
  • Take Over the World: Himiko's plan at the end of the world, with the objective of ending the battles between nations. As much other things she does, it's an imitation of Nobunaga.
  • There Was a Door: Lu Bu constantly crashes through walls.
  • Tsundere: An erotic scene unlocked during Marco Polo's missions reveals she is into the protagonist, but even then she tries to repel its thoughts because she also sees him as interfering in her desire for Kublai.
  • Winds of Destiny Change: Ashoka's Curse ability affects her opponents negatively, but it is impossible for her to determine which one of the stats will be affected.
  • Yandere: Marco Polo actually thinks on stabbing the protagonist dead as Kublai Khan keeps getting closer to him.
  • Zerg Rush: Egyptians only attack like that. It makes complete sense since they aren't really officially at war with Zipang, as much as they think they injured their queen and are attacking on a mad frenzy. Yoshitsune even recommends giving up temporarily in conquering Egypt because they just keep coming in large waves.
