In an alternate universe, the major figures of the Warring States period were all women. Right after the incident at Honnou-ji, something happens, flinging this world's Nobunaga through time and space into our world - modern day Tokyo, to be exact. Within her first day of arrival, she runs into an ordinary boy, names him her retainer, and is set with a mission. She must find the Secret Treasures in order to return home. Of course, other figures from the past will follow after her.Based on a cell phone game, Sengoku Collection was turned into a Spring 2012 Anime. It can be watched at Crunchyroll.
Darker and Edgier: The episode focusing on Masamune. Not just just the storyline, but also the artwork.
Deliberately Monochrome: Kanetsugu's view of the world eventually turns into this, when she realizes that Kenshin no longer wishes to be a conqueror, and much prefers the peace of the modern world.
Determinator: A trait that Ieyasu and her entertainment rolemodel Rosary surprisingly share. Ieyasu's manager describes even describes how the latter never allowed herself to say she's giving up, or is unable to do what's been given to her.
Early-Bird Cameo: Akechi Mitsuhide can be seen during a short segment at the start of the series as well as in the first OP, but she only really gets focused on late during the second half of the show's run.
Engineered Public Confession: Used against the documentary filmmaker Morse after he releases a biased documentary to turn public opinion against the samurai girls.
Ensemble Cast: The closest thing the show has to a main character is Oda Nobunaga, but she gets at minimum two or three episodes focused on her. The show switches characters every episode, and while Nobunuga does show up at the end of most, it's probably safe to say she isn't a main character.
Eye Catch: Of a very fanservicey type too, where the first half shows a close-up image of the focal Sengoku girl, while the second half shows her tastefully and artfully naked. The only members of the cast who seemed to have escaped this treatment are Kanetsugu and Kenshin, likely because they shared a single episode focus.
Greek Chorus: The three animal-eared miko part of this role.
Green-Eyed Monster: Mitsuhide's need to be useful to Nobunaga eventually morphs into this when she starts to feel overshadowed by the other generals, especially since unlike many of them, she doesn't start out with a Treasure of her own. This culminates in her blowing up Nobunaga's fortress, which kickstarts the forced exodus of the Sengoku generals to our world.
Heroic Self-Deprecation: Ieyasu feels that she could never get anything right, nor live up to the image she has of Rosary; however everyone else sees that she has the latent talent and charisma to become even a bigger star than her role model.
Hikikomori: Episode 9 starts with Shinkuro in this situation due to depression and her host family trying to get her out into the world.
I Choose to Stay: While many of the Sengoku generals miss their home world, many of them have acclimated so much to modern-day Earth that they don't really mind when Nobunaga comes to take their treasures away.
Idol Singer: Rosary, who inspired Ieyasu to become one.
Innocent Prodigy: Bokuden is a powerful sword master and teacher of her own dojo. She's also a little girl who has among her top concerns stopping a crooked documentary ruining public opinion for the Samurai girls and being able to play with her friends.
Tsunehisa in episode 23, is a genius tactician at age four. She uses her gifts to take over the playground sandbox.
Kimono Fanservice: Of the very lying low on the shoulders and revealing a LOT of cleavage type. Kenshin is an early example of this, but she's not the only one over the course of the series.
Meido: Shinkuro's default outfit resembles a maid uniform decorated with triforces.
Miko: Three of them, Fox, Cat and Rabbit, who exist across time and space, and give Nobunaga her mission.
My God, What Have I Done?: Mitsuhide's horrified reaction in the first episode to her causing the destruction of Nobunaga's fortress.
Out of Focus: Nobunaga at times. Not too surprising though, given how her quest to find the treasures usually takes a back seat to the stories of the Sengoku-era warlord a particular episode is centered on.
Poor Communication Kills: One can say that the primary reason why the Sengoku generals are even being thrown into modern-day Earth in the first place is Nobunaga's sheer inability to be honest with Mitsuhide.
Pretty Freeloaders: Played absolutely straight by Nobunaga in the first episode, where she shacks up with the poor sod she literally drops into. Many of the other girls who haven't found any local work, or are too young to get jobs, are assumed to do this as well.
Recurring Extra: The other role the mikos play, where they usually appear in an episode just to add to the people the Sengoku general focused on interacts with.
Serious Business: Episode 23, featuring four year old Tsunehisa taking over the playground sandbox, is presented in the style of a historical war documentary. It goes so far as to describe the use of a hose during a mud-fight as a superweapon or referring to one girl telling on Tsunehisa as a "betrayal of child society."
Unusually Uninteresting Sight: While the world is initially baffled by all these Sengoku-period female generals falling from the skies, it eventually becomes an accepted part of life, especially when some of them (like Ieyasu and Kenshin) become well-known celebrities.
