In the near future, the outbreak of a terrible disease called the Apocolypse Virus places Japan under the military rule of a global organization called the GHQ - a group tasked with checking the spread of the virus and administering vaccinations. Apathetic high school student Shuu Ouma lives in Tokyo, spending his days editing videos and trying to be left alone. But things change when he meets the beautiful pop idol, Inori, who is on the run from GHQ soldiers. While trying to save her from her captors, he acquires a mysterious power called the Void Gene that allows him to pull items or weapons from anyone under the age of seventeen. Now, Shuu must decide whether to join the efforts of the well-funded radical terrorist group "Funeral Parlor" and fight against the GHQ, or shrug off his newfound power and resume his normal life - assuming that either the GHQ or Funeral Parlor's charismatic leader, Gai, will let him.
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.
The main reason behind this recommendation is that the characters between the two series seem very similar. In both, there is a teenage boy who is forced by circumstances to fight for something he does not really believe in. Both of these characters suffer from a severe lack of self-confidence. They also have an attraction to the mysterious heroine that they interact with. Rei from Evangelion and Inori from Guilty Crown both seem to have trouble in expressing emotions, have a past that is shrouded in mystery, and an unclear relationship with the leader of the different organizations; Rei with Gendo and Inori with Gai.
Towards the latter half of the series the notion of armageddon comes into play, due to an event that occured in the past (Lost Chistmas and the 2nd Impact). Both anime's make reference to Adam and Eve and both Animes have similar characters, mecha action, themes and character tropes.
Souma and his friends were typical high school students, and members of the student council; but things changed when a cat girl named Mao appeared in the school, looking for someone named Zero. Souma accidentally breaks Mao's mirror which causes her, Souma and his friends to be transported to her world. In this world, Souma and the other male humans from Earth can wield soulblades drawn from people's hearts. His friends landed in different parts of a war-torn world, so they have subsequently broken up into separate factions and each person is working towards winning the war. His friends have become each other's enemies, and it's up to Souma to be the one to create peace without choosing which friends should die.
Enjoy how a protagonist - who is suddenly and directly thrown into the midst of a warring environment - pulls out different weapons from people and uses them for battle? See it happen again!
Both anime have main character thrown into battle and pull out peoples souls in the form of a weapon to fight.
The year is 2022, and gamers have lined up on launch day for Sword Art Online, a hotly-anticipated MMORPG that lets players connect to an immersive virtual reality world with special helmets called Nerve Gear. Kirito is one such gamer who's eager to jump back into action, having spent a great deal of time as a beta tester, and quickly becomes friends with newbie warrior Klein. But soon, Sword Art Online's 10,000 players discover that not only are they unable to log out, the only way they can return to their physical bodies is by beating the 100-level tower's final boss - that is, if their HP doesn't drop to zero first, for death in the game means death in the real world. Now, with no one else to turn to, Kirito and the other participants must survive the game as best they can – some forming guilds, others ruthlessly leaving their peers behind, and many tragically falling by the wayside or to the merciless monsters populating the lands...
Both have main characters that are "normal" people who get caught up in something way bigger than themselves and obtain some form of unearthly power to help them save the world. So what if one of them is in the real world and the other is in a game world? They have a similar style and feel; if you like one...I'm not going to say you'll like the other...but I bet you will.
Both contain a hero who goes on an epic journey that involves self-discovery, love, and awesome fights, and they'll both make you cry if you really get into your anime
Death and reincarnation are inescapable, but what happens in between? Without warning and without his memories, a boy who only recalls his last name - Otonashi - wakes up next to a girl named Yuri who offers him a gun and tells him to shoot an angel. Assuming it must be a misunderstanding, Otonashi is then almost killed by the angel and is drawn into Yuri's army to battle to delay the beginning of his next life. Immortality is within reach, but if Otonashi remembers how he died, will he keep fighting or allow himself to vanish?
Hakaze, princess of the Kusaribe mage clan, has been betrayed and marooned on an island by her own people. They seek to revive the Tree of Exodus, an incomprehensibly powerful entity of alien origin, to save the world from the tyranny of its antithesis: the Tree of Genesis that powers their magic. Hakaze, however, believes their efforts put humanity in jeopardy; and with her power limited, she can only reach out to the world to beg for aid. Her call reaches Mahiro Fuwa, a young man grieving the mysterious death of his sister, Aika. He and his friend Yoshino agree to help - on the condition that Hakaze track down Aika's killer with her magic. The deal is made, and the battle that will determine civilization's fate is begun: but who will play the part of its villain, and who its savior?
1) Both animes are set in apocalyptic Japan
2) Both apocalypses are caused by a source that makes people´s body turn into crystal/metal
3) Main characters are bound by friendship
4) Some higher power (state, the powerful) is trying to suppress/kill them
