Sequel of Touken Ranbu: Hanamaru.

Shuu Tsukiyama is a "ghoul": a creature who eats human flesh, and he likes to enjoy his meals to the fullest. One night, while relishing in the premeditated murder of his dinner, Shuu's much anticipated first bite is disturbed by a sudden flash of light. The flash turns out to be from the camera of high schooler Chie Hori, who presents Shuu with the perfect picture capturing his true nature; the extremely clear shot of a bloody corpse and an overly excited Shuu threatens to expose his ghoul identity, thus Shuu needs to sort out this situation quickly. After Shuu discovers that Chie attends the same high school as him and is even in the same class, the reason behind his feelings of obsession changes from self-preservation to morbid curiosity. As he grows closer to the absent-minded and extremely odd photographer, he challenges them both to learn more about each other's conflicting worlds; Shuu promises that Chie will come out of this experience with a photograph superior to the one she already has.

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. [Written by MAL Rewrite]
