Shingeki No Kyojin(Attack On Titan) Season 1 Episode 1

Over 100 years before the beginning of the story on an alternate world, giant humanoid creatures called Titans suddenly appeared and nearly wiped out humanity, devouring them without remorse or reason and only targeting them; they completely ignore other wildlife. What remains of humanity now resides within three enormous curtain walls: the outermost is Wall Maria the middle wall is Wall Rose, sometimes pronounced like rosé) and the innermost is Wall Sheena , alt. "Wall Sina". Inside these walls, humanity has lived in uneasy peace for one hundred years, many people growing up without ever having seen a Titan. This all changes when one day, a giant 60-meter tall Colossus Titan mysteriously appears after a strike of lightning and breaches the outer wall (which is 50 meters tall) of the Shiganshina district, a town at Wall Maria, allowing the smaller Titans to invade the district. An Armored Titan smashes clean through the gate in Wall Maria, forcing humankind to abandon the land between Wall Maria and Wall Rose, evacuating the remaining population into the inner districts. The sudden influx of population causes turmoil and famine. The Titans are giant humanoid figures ranging between 3 and 15 meters tall and are usually masculine in body structure but lack reproductive organs. Although they do not appear to need food, they instinctively attack and eat humans on sight; it is mentioned that they derive their energy from sunlight. Furthermore, the Titans also do not have a proper digestive tract; once they have eaten their fill of human prey, Titans will vomit large, slimy balls, derisively referred to as "hairballs", as shown in the episode where the squad retakes Trost. Finally, their skin is tough and difficult to penetrate, and they regenerate quickly from injuries, except for a weak spot at the nape of their neck. Combating the Titans is the military, which is divided into three branches. Foremost in the story is the Survey Corps, which goes out into Titan territory to try to reclaim the land. The Survey Corps is heavily derided in society because of its apparently senseless high casualty rate and little sense of progress. The second and largest branch is the Garrison Regiment which guards the walls and the civilian populace. The third branch is the Military Police Brigade which guards the royal family and lives relatively relaxed lives in the innermost wall, although this eventually results in fraud, corruption, and political subterfuge. The soldiers use a grappling, tethering system called Vertical Maneuvering Equipment that allows them to jump onto (and swing from) walls, trees, or nearby buildings to attack Titans with dual swords, and use gas canisters which to propel themselves. However, despite it being the soldiers' primary line of both offense and defense against the Titans, it is useless in open and flat terrain like fields. (TO BE CONTINUED)
