Devils cannot take form without a living host. However, if the will of an individual is strong enough, they can overcome the demon and make its power their own, becoming a Devilman. Weak and unassuming, Akira Fudou has always had a bleeding heart. So when his childhood friend Ryou Asuka asks for his help in uncovering devils, Akira accepts without hesitation. However, to Akira's surprise, the place they go to is Sabbath: an immoral party of debauchery and degeneracy. Amidst bloodshed and death, demons possess the partiers, turning their bodies into grotesque monsters, and begin wreaking havoc. In a reckless attempt to save his best friend, Akira unwittingly merges with the devil Amon and becomes a Devilman, gaining the power to defeat the remaining demons. Though it grants him great power, this new partnership awakens an insatiable and primeval part of Akira. Having the body of a devil but the same crybaby heart, Akira works alongside Ryou, destroying those that harm humanity and his loved ones.

Having slept through all four of her alarms, the energetic Narumi Momose finds herself running late for her first day of work at a new office. As she races to catch her train, she makes a promise to herself that none of her coworkers will find out about her dark secret: that she is an otaku and a fujoshi. Her plan goes instantly awry, though, when she runs into Hirotaka Nifuji, an old friend from middle school. Although she tries to keep her secret by inviting him out for drinks after work, her cover is blown when he casually asks her whether or not she will be attending the upcoming Summer Comiket. Luckily for her, the only witnesses—Hanako Koyanagi and Tarou Kabakura—are otaku as well. Later that night, the pair go out for drinks so that they can catch up after all the years apart. After Narumi complains about her previous boyfriend breaking up with her because he refused to date a fujoshi, Hirotaka suggests that she try dating a fellow otaku, specifically himself. He makes a solemn promise to always be there for her, to support her, and to help her farm for rare drops in Monster Hunter. Blown away by the proposal, Narumi agrees immediately. Thus the two otaku start dating, and their adorably awkward romance begins.

Yoichi Isagi was mere moments away from scoring a goal that would have sent his high school soccer team to the nationals, but a split-second decision to pass the ball to his teammate cost him that reality. Bitter, confused, and disappointed, Isagi wonders if the outcome would have been different had he not made the pass. When the young striker returns home, an invitation from the Japan Football Union awaits him. Through an arbitrary and biased decision-making process, Isagi is one of three hundred U-18 strikers selected for a controversial project named Blue Lock. The project's ultimate goal is to turn one of the selected players into the star striker for the Japanese national team. To find the best participant, each diamond in the rough must compete against others through a series of solo and team competitions to rise to the top. Putting aside his ethical objections to the project, Isagi feels compelled to fight his way to the top, even if it means ruthlessly crushing the dreams of 299 aspiring young strikers.
