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.
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.
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.
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.
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.
