Brave 10 is a Jidai Geki fantasy anime, originated from the similarly named manga. It follows the lives of those that would be known as Sanada Ten Braves, ten loyal ninjas serving under Sanada Yukimura, although rather than going for historical route, they go for a more mystic-based approach.The main protagonist is an Iga ninja named Saizou, who meets an Izumo priestess called Isanami on the run from the ninjas who destroyed her temple and protects her on her short journey to Sanada Yukimura's castle. Sanada wants to gather 10 warriors, a party unrivaled in skill and power, to set his still secret plan into action...The author, Kairi Shimotsuki, is well known for her Yaoi work, but she has also worked on the Sengoku Basara franchise and this series clearly follows the latter. Very much so, though with a heavy, Darker and EdgierSeinen slant.
Anachronism Stew: For some reason, Isanami is at the center of most anachronisms, what with her biker shorts, ballet moves and lollipops.
Anti-Hero: Kamanosuke and Anastasia are not really heroes, they simply are in the side of good - Kamanosuke in fact is the Token Evil Team Mate. Saizou is in the other hand your average bad boy with rough habits but goodie instincts awakened by Isanami.
Big Damn Heroes: In the manga, Juuzou arrives just in time to drive Hanzo out. Kamanosuke does the same later. And Seikai, Sasuke and Kamanosuke later as they face Benmaru's Death Course. Sort of a habit
Bread, Eggs, Milk, Squick: While Saizo is complaining about the other braves goofing off images show Sasuke hanging out with his animals, Anastasia sitting by a river and Kamanosuke threatening a villager.
Broken Bird: Anastasia is tough, self-reliant and cold, and chafes at the safety of Yukimura's castle. Don't expect her to defrost easily. Though if her fight with Jinpachi is any indication, it could be nearer than we thought.
She got better and stops being a villainess, but she still is in an Ice Queen, not giving in to Jinpachi's sexual advances.
Calling Your Attacks: Saizou, Seikai, Anastasia, Hanzo, Kaio can't apparently use their techniques without informing everyone of their names. The rest of the Braves are more discreet.
Combat Pragmatist: When Isanami isn't around to stop them the ninja side of the team delivers coup de graces and does whatever it takes to win the fights. They are not samurai, after all.
Compressed Adaptation: After the first episode of the anime, which covers slightly past the first chapter of the manga, the anime races through the source material, covering over 120 pages worth of manga each episode: most of the cut material featured Those Two Bad Guys, who were left out of the anime adaptation and are pretty much nothing but comic relief. See Pragmatic Adaptation.
Cool Big Sis: Anastasia becomes Isanami's sister figure after she rescues her from Date. With a hint of Good Bad Girl in the way she flirts with Yukimura and Saizou. Bad idea, because Ana actually hates familial concept, and it was all an act, probably devised by Hanzo to eventually break Isanami.
Crater Power: When Isanami uses her power she is left standing in a shallow crater.
Crossdressing Voice: Young Seikai is actually voiced by a female. It's a wonder how his vocal evolved that his current voice is done by a male, and a non-androgynous voice at that.
Cry into Chest: Isanami breaks down on Saizou after Yukimura refuses to help her early in the story.
Dark and Troubled Past: Anastasia saw her family dead in Japan and have been left alone since little, and while looking for the last heirloom of her family, there came Hanzo holding it and blackmails her to join, shaping her into a cold hearted woman. This is also why 'family' was some sort of Berserk Button for her and what made her hate the rest of the Braves.
Dragon with an Agenda: Unfortunately for Ieyasu, Hanzo has his own plans for capturing Isanami, and pretty much cares less about the upcoming Tokugawa vs Toyotomi clash, his team would be the one ruling from the shadow... or so he claims.
Dragon Lady: Oukatsu; open kimono, humongous cleavage, hidden blade, snake powers. Succeeded by Kaio, her sister.
Dude Looks Like a Lady: Kamanosuke has to do very little to look feminine something he used to ambush people during her times as a bandit. Although maybe it's just that she looks masculine, as seen in the Lotus-Eater Machine..
The Dulcinea Effect: The first time he saves Isanami was just self-defense. And the second time, too. And the third...
Epiphany Comeback: During his fight with renegade Iga ninja Goemon, Saizou is thoroughly beaten until Goemon tells him he's no longer an Iga ninja. Saizou realizes he should think like a one of Yukimura Braves. Cue fight reversal.
Heel-Face Turn: Or Neutral Turn. Once Hanzo is dead, Ana already claimed that she can't come back to Yukimura for being a traitor. The good thing is, Jinpachi is there to offer her a place to stay, and he doesn't seem to be interested in staying in Ueda all the time.
Faux Affably Evil: Hanzo is 100% evil, but he's quite a polite talker in describing on how much he's killing people. Also exemplified in his monologue for Episode 11 preview.
Five-Bad Band: Five Iga Ninjas. Subject to change depending on the last reveal:
Flat Character: Unfortunately, most of Hanzo's five (including Hanzo himself) has very little background and look like they're just in for simple megalomania, aside of Anastasia, who's shown to have Dark and Troubled Past and had other goal unlike them
Forced Into Evil: Zig-zagged. Turns out, the reason why Anastasia joined Hanzo was because Hanzo was holding her family heirloom that she's been searching since little. However, given enough time she spent with Hanzo, she turned into a cold-hearted Broken BirdIce Queen who's just as bad as Hanzo is. But, even Jinpachi could see her slowly being defrosted despite her insisting otherwise.
Get a Hold of Yourself, Man!: Saizou need Sasuke to give him a pep talk after being thouroughly beaten by Hanzo during their first fight (or getting Isanami captured by Masamune in the anime).
In particular, Hanzo probably got it the worst. At most, Ieyasu is depicted as an incompetent Smug Snake (which is lampshaded by Masamune). Hanzo goes beyond being 'loyal' to Ieyasu into having probably different goals than Ieyasu and being much more sadistic and quite making his way to Hero Killer.
Though there could be some good justification on this. 'Hattori Hanzo' is a title passed down through Iga ninja leaders, this Hanzo may not be the same with the same Hanzo that escorted Ieyasu through Iga after Nobunaga's death (Hattori Masanari). In fact, there is a Hanzo that is really mean even to his own kinsmen.
It's All My Fault: Isanami come to this conclusion after the second fight with Hanzo and briefly gives up. She's then goaded by Hanzo during the fight against the Five into another breakdown that pulls out her Superpowered Evil Side.
Pragmatic Adaptation: Because of time constraints, in the anime some characters dissappear and others take their roles in some arcs, some fights and events are cut and some villains are somewhat weakened. And because of Moral Guardians, a general helping of Bleached Underpants.
Sequel Hook: Yes, Izanami is calmed down, and Hanzo and his five except Anastasia are dead. However, there's still Masamune and Ieyasu (whose casualties are probably just missing out Hanzo), all ready to wage war.
Shaggy Dog Story: It turns out, the heirloom Anastasia is looking for which was in Hanzo's hand was fake.
Shoot the Shaggy Dog: If you're a history maniac, you'll know. No matter how badass the Braves got, they're destined to die with Yukimura during the Siege of Osaka.
Survivors Guilt: Isanami is weighed down by the destruction of her temple (being her adoptive family, too), but she rarely lets on it, like when she did to Saizou after believing Yukimura wouldn't help her.
Taking the Bullet: The Head Priest of Izumo to save Isanami at the opening of the series.
Terse Talker: Sasuke finds easier to talk with animals than with people.
These Hands Have Killed: While trapped with Isanami after the fight with the giant snake, Saizou tells Isanami he's just a killer and cannot be anybody's shining knight.
Those Two Bad Guys: Ichimaru and Niko, fairly ineffective ninja villains and comic relief who first appeared attempting to rape Anastasia during her introduction. They are absent from the anime adaptation except for a brief cameo in episode five.
Trash Talk: Hanzo teases Saizou continously on the gap between his fame and his actual skill during their first fight.
Trauma Conga Line: This is actually an omnipresent presence in-story too, according to Yukimura. Any time Isanami fell into some trauma or sadness, the power of Izanami spreads out and kills everything nearby, and Kushimitama is only surpressing the power. And making matters worse, Isanami overheard this while trying to recover from the trauma of Ana's betrayal. Nice job being a Mr. Exposition in the wrong time, Yukimura
Villainous Crossdresser: Goemon. Since his whole family was targeted to be exterminated, he had to disguise himself as a girl. Also, Kamanosuke Yuri would use this to trick people while he was a bandit.
Wham Episode: Hoo boy, episode 9. What would be a good night sleep went downhill when Ana is revealed as The Mole for someone who's presumed to be Hanzo, goes on to cripple Rokurou (and forced him to sacrifice an important information on his eye) and Sasuke, and Yukimura reveals the reason why he wanted to gather the Brave 10... Surpress the power of Japanese Death Goddess Izanami... incarnated into Isanami. And she overheard that too.
What Is This Thing You Call Love?: Kamanosuke doesn't get what love/affection is and it confuses him, so he approximates it to what he likes most: killing. His relationship with Saizou is colored by this.
