4. Sword Art Online
In the year 2022, virtual reality has progressed by leaps and bounds, and a massive online role-playing game called Sword Art Online (SAO) is launched. With the aid of "NerveGear" technology, players can control their avatars within the game using nothing but their own thoughts.
Kazuto Kirigaya, nicknamed "Kirito," is among the lucky few enthusiasts who get their hands on the first shipment of the game. He logs in to find himself, with ten-thousand others, in the scenic and elaborate world of Aincrad, one full of fantastic medieval weapons and gruesome monsters. However, in a cruel turn of events, the players soon realize they cannot log out; the game's creator has trapped them in his new world until they complete all one hundred levels of the game.
In order to escape Aincrad, Kirito will now have to interact and cooperate with his fellow players. Some are allies, while others are foes, like Asuna Yuuki, who commands the leading group attempting to escape from the ruthless game. To make matters worse, Sword Art Online is not all fun and games: if they die in Aincrad, they die in real life. Kirito must adapt to his new reality, fight for his survival, and hopefully break free from his virtual hell.

2. Steins;Gate
The self-proclaimed mad scientist Rintarou Okabe rents out a room in a rickety old building in Akihabara, where he indulges himself in his hobby of inventing prospective "future gadgets" with fellow lab members: Mayuri Shiina, his air-headed childhood friend, and Hashida Itaru, a perverted hacker nicknamed "Daru." The three pass the time by tinkering with their most promising contraption yet, a machine dubbed the "Phone Microwave," which performs the strange function of morphing bananas into piles of green gel.
Though miraculous in itself, the phenomenon doesn't provide anything concrete in Okabe's search for a scientific breakthrough; that is, until the lab members are spurred into action by a string of mysterious happenings before stumbling upon an unexpected success—the Phone Microwave can send emails to the past, altering the flow of history.
Adapted from the critically acclaimed visual novel by 5pb. and Nitroplus, Steins;Gate takes Okabe through the depths of scientific theory and practicality. Forced across the diverging threads of past and present, Okabe must shoulder the burdens that come with holding the key to the realm of time.

1. Death Note
A shinigami, as a god of death, can kill any person—provided they see their victim's face and write their victim's name in a notebook called a Death Note. One day, Ryuk, bored by the shinigami lifestyle and interested in seeing how a human would use a Death Note, drops one into the human realm.
High school student and prodigy Light Yagami stumbles upon the Death Note and—since he deplores the state of the world—tests the deadly notebook by writing a criminal's name in it. When the criminal dies immediately following his experiment with the Death Note, Light is greatly surprised and quickly recognizes how devastating the power that has fallen into his hands could be.
With this divine capability, Light decides to extinguish all criminals in order to build a new world where crime does not exist and people worship him as a god. Police, however, quickly discover that a serial killer is targeting criminals and, consequently, try to apprehend the culprit. To do this, the Japanese investigators count on the assistance of the best detective in the world: a young and eccentric man known only by the name of L.
