High school student and gamer Suigin Riku attends the prestigious Shinryou Private Academy, a school for the elite and the children of the wealthy. But rich or wealthy are not words that describe Suigin; in fact, he is dirt poor and must work many part time jobs to pay for his tuition. During one such job, he dives into a pool to save his pet cat, fully aware that he cannot swim. Luckily, he is saved by Rei Riku, the beautiful and popular daughter of a game developer, and he falls in love with her. He is also drawn to another girl: a new friend he meets in Dungeon Century, his favorite online RPG. But when the game is scheduled to shut down, he knows his adventures with her will soon end. However, the day after the game is shut down, he finds out that Rei and the online girl are one and the same. Soon after, Rei gives Suigin a new game meant to replace Dungeon Century—a tomb raiding game called Grave Buster. But when Rei is suddenly kidnapped, Suigin is pulled inside Grave Buster to save her. Gin no Guardian follows Suigin as he plays through Grave Buster to save Rei, while uncovering the secrets hidden within the game. [Written by MAL Rewrite]

Meek salaryman Johnson discovers that he is in fact the notorious (and reportedly dead) space pirate Cobra, with a new face and altered memories. Embedded in his left arm is Cobra's unique Psychogun, a famous weapon powered by his own will. Having recovered his past, his partner-in-crime Armaroid Lady, and his spaceship, he journeys across the galaxy seeking adventure. On his travels he will hunt for the galaxy's ultimate weapon, rob museums, break into and out of maximum-security prison, infiltrate a drug ring in the brutal and deadly sport of Rugball, engineer a coup on an alien world, confront the Pirate Guild's most fearsome leaders, and do much else besides—smoking cigars, chasing women and cracking jokes all the while. This, the 1982–83 Cobra TV anime, adapts the Cobra manga from the beginning, covering the first three major stories and building to a grand conclusion with some shorter one-off tales interspersed along the way. (The 1982 Cobra film has only a loose connection to the TV series—though it involved the same director and some of the same animators.)

A Romance of the Three Kingdoms retelling using SD Gundams.

In A.G. 101 (the 101st year of the Advanced Generation calendar) a mysterious entity known only as "UE", or "unknown enemy", attacks and destroys the space colony Angel. This brutal attack becomes infamous as the "The Day the Angel Fell", and marks the beginning of humanity's war for survival. The series begins in A.G. 108 when the UE attack the space colony Ovan, where Flit Asuno lives with his mother. Flit's mother is killed by the UE, and in her belongings (in an object called a "AGE Device") he discovers the blueprints for a powerful weapon from the past - the ancient messiah named "Gundam." From these blueprints, Flit spends the next several years studying engineering at an Earth Federation base on the Nora space colony and designing the AGE-1 Gundam. Seven years later, in A.G. 115, Flit completes the Gundam, just as the UE attack Nora. Flit and his lineage's battle piloting the AGE-1 to protect mankind is about to begin. (Source: GoodAnime.net)
