If you liked the Shingu: Secret of the Stellar Wars anime, the Anime-Planet community thinks you'd like:
The year is 1969, and strange things are happening on Earth: a strange formation known as Brigadoon has appeared in the sky, and mysterious alien machines have begun to attack a seemingly ordinary orphan girl named Marin! Luckily for her, Marin finds an artifact which summons the alien Melan Blue to protect her – but there is more going on between Earth and Brigadoon than meets the eye. However there is more going on behind the scenes between Earth and Brigadoon. Along with a cast of quirky characters, Marin must get to the bottom of what’s going on, lest both Earth AND Brigadoon be destroyed forever!
Both of these titles have a certain vibe that is both light hearted at times and can get serious as well. Shingu a tad bit more lighthearted than Brigadoon.
The over all "look" of the designs are very fresh and unique.
Both deal with the same age kids.
Several years ago, Jin Kamishina's family was killed in what appeared to have been a space shuttle accident. A few years later he is suddenly attacked by a strange monster, but is saved by a strange girl named Toa who possesses superhuman strength and can transform into a dragon. Jin finds out that the accident was not due to an error by his father, the pilot, but rather as a result of a collision with an object from outer space – the asteroid Thanatos, the source of destructive dragons appearing on Earth. As they make new friends and enemies, Jin and Toa now find themselves becoming increasingly entangled in the mysteries of the ISDA – a shadowy organization working to protect humanity – and the dragons themselves...
Well these are and aren't similar at the same time. Meaning that even though both are people fighting aliens trying to destroy earth, complicated relationships, the main character guy being weak and the main character girl being strong the animes still have major differences. Mainly the graphics and its hard to say but Shingu is more realistic if you understand what I mean.
While transporting bio-weapon lifeforms, Agent DD, member of an alien police force, is forced to crash land on Earth. Amidst the chaos of the crash, a bio-weapon escapes and DD is forced to fight it, while accidentally activating a Liberus, a liquid battle suit. Tsubasa, a shy girl, unwillingly comes into contact with the Liberius and is thereafter forced to fight for the survival of Earth.
Figure 17 and Shingu are both sci fi told in a very slow-paced, slice of life way. Shingu has more campyness to it (including a ridiculously bad soundtrack) but I definitely think fans of one would like the other. I think Figure 17 is the superior title, though.
Yukitaka has just left Tokyo, eager to transfer to Kisaragi High where he's been recruited to play baseball. However, upon entering his new apartment, the boy is met by a man with long blonde hair who claims to be… an alien?! After initially scoffing at the notion, Yukitaka discovers that the alien – Ouji – is for real, has amnesia and, what's worse, now wants to live with him in his apartment. The fact that scientists and mysterious guys in black suits are after Ouji becomes the least of Yukitaka's problems as his new guest turns out to be more than a handful to handle!
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 these animes are really similar. Both are rated 3 stars in my book and have similar stories. They deal with women with complications with life and battles against aliens trying to destroy earth. The main difference is that there is more fight in Neon Genesis, but more romance in Shingu.
