Half a year has passed since Sousuke Sagara took up the job of protecting Kaname Chidori and has started living like a normal teenager for the first time. A former child soldier, his view on the perils of everyday life is highly unconventional and in frequent need of violent adjustment; Kaname can only hope her endless assault will eventually get him used to normal life. But a shadow looms over their happy days as Sousuke's employer, the private army called Mithril, is attacked by a new unknown enemy. Suddenly outgunned, can Mithril afford to keep one of their best playing around?
In the 24th century, the planet's fossil fuels have been completely consumed, forcing humanity to use solar power as the primary source of energy. A huge solar energy system orbiting the planet was eventually built, anchored to the Earth and providing it with power through three orbital space elevators. As a result of the expense of such a large-scale project, most the world consolidated into three factions: the Union, the Human Reform League, and the AEU. Despite their common reliance on the fragile orbital elevators for energy, however, humanity still continues to constantly fight wars and build up arms. A paramilitary organization called Celestial Being, equipped with incredibly powerful mobile suits called Gundams, fight in order to force humanity to unite and eradicate armed conflict.
While both Gundam 00 and FMP do have mecha battles, they are even more similar in the main characters. Both Sousuke and Setsuna grew up in the midst of fighting and war. This gives each of their characters a unique outlook to the world. So, I think with a mix of action, militaristic combat, and similar main characters, you would enjoy one if you liked the other. Be aware that FMP has comedy/romance while Gundam 00 does not.
War between the Earth Federation and Zeon has ground to a bloody standstill, and both sides eagerly seek a quick resolution. Among these is Ensign Shiro Amada, a young mobile suit pilot for the Federation assigned to the 08th mobile suit division in the heart of the Vietnamese jungle. The members of his team include Karen, a hot-headed pilot and part time mechanic; Sanders "The Reaper," a pilot with a reputation for getting the people in his unit killed; Eledor, an aspiring musician, flirt, and communications officer for the team; and Mikel, the love-struck driver for the team's command vehicle. As the gravity of war bears down on their shoulders, they must struggle to keep their sanity amidst a chaotic battlefield that continually tests their wit, focus, and resolve.
Both series share a realistic connection in terms of war and the soldiers that fight them. There are no immortal supersoldiers. People get hurt physically and mentally as they try to find what they are looking for on and off of the battlefield.
In the future, a devastating event known as Second Impact has destroyed Tokyo as we know it, giving rise to Tokyo III - a city under siege by mysterious lifeforms known only as Angels. Mankind's only line of defense are the Evangelions, a set man-made machines piloted by a trio of fourteen year-old teenagers, Rei, Shinji, and Asuka. The fate of Japan and the entire world now lie with these three children, though they might not have the power to save the most important thing of all: each other.
Both of these mech anime deal with the affect that thrusting teenagers into combat can have on their psyche. Evangelion is much more fruedian and cerebral with that theme while TSR is a little more straight and less mind-f*cky about it, but if you really enjoyed that aspect of one series you'll probably enjoy the other. Also, both of these series have some of the best mecha action scenes I've seen. Kaname is a bit Asuka-ish, too, although Asuka has way more issues than Kaname has.
Sumiregawa Nenene is an author who hasn't published a book in years. However, at a book signing in Hong Kong, things go fascinatingly awry. For starters, her guides are three sisters who operate a detective agency: Maggie, Michelle, and Anita. Then there's the attacks on Nenene's life, and her only line of defense is the three sisters -- who can all use paper as weapons, tools, and even transportation. But can their powers protect Nenene from the mysterious forces that not only want her, but all the precious books of the world...?
There is only one reason for this recommendation: "awesome fighting scenes". They appear very rarely in both series, but if you're a fan of those, you have to see this anime.
P.S. Watching Read or Die before ROD TV as well as watching Full Metal Panic! before watching FMP!: The Second Raid is very recommended.
In the revolutionary Meiji period, Japan is undergoing enormous political change. It is a time when vagabonds and terrorists will use any method to prevent the modernization of their country, even if it means trampling on the innocent in the process. In such a time, Himura Kenshin, a wandering samurai, has dedicated his life to protecting the weak and desperate peasants from those who would oppress them. However, Kenshin has a dark past which threatens to destroy the values he is fighting for. When he meets his new friends Kaoru, Sanosuke, and Yahiko, and tries to build a peaceful life with them, events conspire against him. Can Kenshin overcome the demons within and without, and finally ensure the peaceful future that Japan deserves?
The hinted yet extremely limited romance, the comic relief, and the great fighting scenes; there are plenty of reasons why I could link Kenshin with FMP! TSR.
Despite their completely different genres (mecha vs samurai), in the end both give us engaging shounen anime that kept me interested from start to end.
