''Red Ninja: End of Honor'', known in Japan as ''Red Ninja: Kekka no Mai'' (紅忍 血河の舞 Reddo Ninja Kekka no Mai) ("Red Ninja: Blood River Dance"), is a 2005 VideoGame for the UsefulNotes/PlayStation2 and Xbox platforms, created in a collaboration between the game developer Tranji Studios and the film writer Shinsuke Sato. It was published by Vivendi Games. The game's theme song was performed by Yoko Ishida.
A young girl's world is destroyed when she and her father are attacked by the Black Lizard clan. After witnessing the brutal execution of her father Ryo, the girl is brutally hung with a tetsugen ("iron string", or "wire") from a tree and left to die. Miraculously, she survives and is rescued and adopted into a ninja clan where she obtains complete mastery of her adopted weapon, the tetsugen. Pledging her undying loyalty to her new family, the girl now takes on the name of Kurenai to avenge her father's death and will go to any means necessary.
!!This VideoGame contains examples of:
* ActionGirl: For all her Fanservice-ness, Kurenai can kick some serious ass. One command prompt that you will encounter ingame is for her to dislocate one of her shoulder bones temporarily to gain access into rooms from gaps smaller than she is. She just gives her shoulder a good pop, crawls in, and fades to black; the next scene has her perfectly fine.
* AmazingTechnicolorBattlefield: The final stage doesn't have solid ground per se: you are teleported into a ''gigantic'' cavern, with a whole ''upside-down castle'' as your final area. While the boss battles that take place there are quite plain (and literally plain since the floor is technically the ceiling of the castle), the final, final area [[spoiler: where you kill Chiyome]] is a small patch of green hill, a single tree and pure white nothingness.
* BackStab: A major gameplay mechanic. Being a ninja, you're encouraged to do this as much as possible. And there are many ways to do it.
* BitchInSheepsClothing: [[spoiler: Mochizuki Chiyome]].
* BoobsOfSteel: Kurenai. Her smaller-chested protege Akemi is usually reduced to comic relief.
* CameraScrew: For a game that relies on a lot of platforming, this is the bane of any player.
* CurbStompBattle: The final battle against [[spoiler:Chiyome]] places you both on a featureless plain with your target standing under a tree. They will barely fight back, and you can end the battle simply by hanging them from the neck.
* DistractedByTheSexy: Kurenai can distract soldiers from their post and bait them for an easy kill. Unfortunately, the mechanic is either bugged or is too random, since it doesn't work most of the time. When it does work though, it's really really satisfying to pull off.
* GatlingGood: The MacGuffin superweapon sought after by every faction of the game is a handcrank-operated minigun. It's powerful enough to mow-down a field full of Samurais and the Shogun thought it was such a GameBreaker that it was banned. Shame that other factions don't see it that way and will stop at nothing to seize it.
* KarmaHoudini: The son of Shingen, which has been doing all the bad things that happen to you in game...never gets heard again after the ending. Neither does Oda Nobunaga. This maybe ties to the SequelHook ending, which, unfortunately, will probably never get made.
* MsFanservice: It's worth noting that Kurenai actually appeared in the October 2004 issue of Playboy magazine, in which they did a feature on female video game characters.
* ObviousBeta: This game might not have bugs per se, but it makes so many baffling design choices that it couldn't have had proper playtesting. The issues with the camera, the dash mechanic, critical hits, body part targeting, and especially the Seduction mechanic could be fixed without altering much of the game and it would make the game much better.
* OneHitKill: These are the preferred method of taking out guards, since if you don't, they will alert all nearby enemies to your presence. You can also OneHitKill a guard who's already seen you by [[DifficultButAwesome throwing your wire at his head and yanking on it just before it hits.]]
* OutsideContextVillain: The power struggle between Oda Nobunaga and Takeda Shingen, arms race and later a frantic search for a missing superweapon that can revolutionize warfare, and a band of ninjas who wish for a country they can call their own. So far, so good. But what's the deal with the four-armed demon and the upside-down castle inside a huge cavern with a lava pool inside it? There has been no inkling of supernatural forces at play and the inclusion of the demon and the final level just throws a big swerve into the whole "context" thing...
* PantyShot: The main character wears a low-plunging subdued red kimono/furisode top with...nothing on the bottom. Not only she shows all her leg, you can see that she wears what seems to be the Japanese middle-ages equivalent of a black thong. This shows up most prominently when you need to crawl up a shaft and the camera has to zoom in before transitioning to first person point of view. This is included in the Seduction mechanic where one of the animations have her show her undies by way of tying her sandal laces. This is later averted as she changes into her ninja armor, which somehow leaves the inner thighs open...
* RazorFloss: The Tetsugen is the main weapon of the protagonist, with a kunai at the end. She can toss it at an enemy then run around slicing nearby foes with the wire. There is, in fact, a less-lethal variant of it with weights instead of a kunai and a less sharp string. You can use it to tie down an enemy (or many of them) onto a beam, hang him by his waist or leg, or go straight up homicidal and hang enemies by their heads. Sadly, since there is no practical purpose (other than to look cool) and the problems far outweigh the coolness, many players simply fall back on the lethal wire.
* SequelHook: [[spoiler: Kurenai strikes off on her own. Zenzo wants her to keep his tantou. He says that one day Oda Nobunaga will be gone and they'll be able to meet again. He does tell her that if they meet again and he's an enemy, she should kill him with his tantou]]. Hmm....
* [[TheManTheyCouldntHang The Girl They Couldn't Hang]]: Kunerai was hanged when she was little, but she somehow survived.
* VideoGameCrueltyPotential: ... in huge doses. With the Fundo, which is the weighted attachment for the wire, there are all sorts of unnecessarily cruel things you can do to guards. You could start by hanging them from a raised beam, either by their neck, feet, or waist. Then you can watch them die slowly, or slash at them with your kunai while they helplessly flail about. You could also back up a few steps and throw knives at them for some target practice. And of course some sadistic players will deliberately leave guards hanging in places where other guards will see, just for some sick pleasure. The REAL kicker is that none of this is necessary, and it's much easier to simply cut a guard's throat and move on. In fact, you often have to go out of your way go hang guards in this fashion, making it that much more cruel.
** You can also tie a guard to a pole and do the same sorts of things.
* ZeroEffortBoss: See Curb Stomp Battle entry above.
