Shio Ogura is a Japanese high school student, who is visiting Taiwan on a school trip when she is suddenly attacked by monsters. Agents known as "E-Gene Holders" from the government agency DOGOO also arrive, who wield weapons infused with the spirits of historical figures. Shio is revealed to also be an E-Gene Holder when the soul of Oda Nobunaga awakens after she tries to rescue a friend.Part of the Winter 2014 Anime lineup.
Beethoven Was an Alien Spy: Florence Nightingale was the original Jack the Ripper. Florence Nightingale, of all people. Of course though, she was actually a secret intelligence agent protecting humanity from a man made bacteriological weapon that was injected into the organs of the women that she regretfully had to kill.
Career-Ending Injury: Robert Capa suffered an unspecified one that forced him to give up field work and have to train new recruits instead. As of Episode 9, Galileo may also have suffered one.
Car Fu: Saint-Germain rams an Invasion Object in episode 9, though that's not enough to do more than distract it for a few seconds. He also spends the entire encounter complaining about having to total a car when the DOGOO budget is so tight.
Cat Smile: Galileo has a perpetual one plastered on her face, to go along with her cutesy personality.
Failure-to-Save Murder: Shio believes that she's responsible for the blowing-up of a significant part of Kaohsiung, due to her failure to shoot the EIO that triggered the explosion. Asao disagrees.
Government Conspiracy: The whole Jack the Ripper thing was a massive coverup by the government for what really happened. The murders were actually committed by secret intelligence agent Florence Nightingale in order to contain a man made bacteriological weapon infected to the organs of the women she regretfully killed from spreading throughout all of Europe.
Hidden Buxom: Possibly. When Shio was in training with Robert Capa, he made a number of mirror-image clones of Shio and tried to provoke her by unzipping one of the clone's track jackets, whereupon the clone was revealed to have a healthy D-cup. Later he uses the clones to do a fake photo shoot of Shio in a bikini for the soldiers and some helpful footnotes remark that the pictures were photoshopped, so it's unclear as to whether Capa was sincerely just screwing with her or if she's really hiding something underneath her usual attire.
Downplayed, as its revealed in episode 8 through a dream sequence that Shio does have an appreciable bust hidden underneath her usual wardrobe. It's just not as full as her clones (or Asao, for that matter)
More Dakka: The heart and soul of the show, not to mention the protagonist's.
In fact, there's a specific quote from Nobunaga in regards to this.
"Even if you have a rifle squad, a single line will be broken while they reload."
"What you must do is simple"
"If one line isn't enough... two!"
"If two lines isn't enough... three!"
Which is accompanied by Shio pulling out more and more guns to shoot the enemy.
Only a Flesh Wound: Jack The Ripper don't feel like quitting the fight, even though he has been gutted in the stomach.
Otaku: Shio is one for weapons. Her room is covered in model tanks and airplanes, and she has a camo-pattern filter, versus other girls' flower patterns, in some of the artsier shots. She's also capable of identifying various military weapons.
Power Perversion Potential: Robert Capa (Anush's) powers include the ability to create copies of people. Not only was he able to "motivate" Shio into aiming better during a training exercise by threatening to take a peek at "her" breasts, he was also able to make her copies pose for some swimsuit photos, to her understandable displeasure.
Reality Ensues: During Nobunagun's first battle, the recoil from her overly large weapon caused her to miss quite a few of her shots.
Really 700 Years Old: Both the DOGOO Commander and Saint-Germain. The Commander, while she does look elderly, is well over 1700 years old, thanks to numerous long periods of stasis during the collection of the E-genes, while Saint-Germain is around 1000 years old and heavily implied to be immortal.
Recoil Boost: In episode 4, Jack asks Nobunagun to use the recoil of her guns to propel them after falling invader eggs. Three guns would give them some ability to steer.
Reincarnation: Explicitly stated to be the case for why the characters have their powers. Shio is also evidence that the powers are not the only thing that may be passed on, as she shares Oda Nobunaga's love for military machinery (guns in particular).
Shown Their Work: In the final episode the true identity of the original Jack The Ripper is revealed and it's mentioned that the name came from a letter written by a journalist rather than Jack themselves.
The creators definitely did their research into historical figures as shown by how the e-genes influence the behavior of their reincarnations, as a lot of the quirks are based on relatively-unknown facts, rumors, or stories about the historical figures. For example, Gandhi was known to love having sex before becoming the person he was known as, so his reincarnation is a playboy. Issac Newton was rumored to live a life of chastity, so it makes sense that his reincarnation is taking every opportunity he denied himself. This also explains why Jack the Ripper comes off as the most normal of the group early in the series. He doesn't show the quirky behavior that every other e-gene holder shows because the real Jack the Ripper was never found; no one knows what quirks the original Jack had, so current-day Jack ends off relatively normal.
Token Evil Teammate: It's mentioned that DOGOO often sends in Jack the Ripper alone because the other E-Gene holders are scared of him. It turns out be an Informed Attribute since everyone treats him rather cordially.
