After dying a laughable and pathetic death on his way back from buying a game, high school student and recluse Kazuma Satou finds himself sitting before a beautiful but obnoxious goddess named Aqua. She provides the NEET with two options: continue on to heaven or reincarnate in every gamer's dream—a real fantasy world! Choosing to start a new life, Kazuma is quickly tasked with defeating a Demon King who is terrorizing villages. But before he goes, he can choose one item of any kind to aid him in his quest, and the future hero selects Aqua. But Kazuma has made a grave mistake—Aqua is completely useless! Unfortunately, their troubles don't end here; it turns out that living in such a world is far different from how it plays out in a game. Instead of going on a thrilling adventure, the duo must first work to pay for their living expenses. Indeed, their misfortunes have only just begun!

Death is one of many mysteries that has left humanity in the dark since the dawn of time. However, the burning question of what happens to the soul after one dies is soon answered to 17-year-old Yuzuru Otonashi. Waking up with no previous memories in a dimension between life and death, he discovers the unsettling truth of the afterlife. Taking the form of a high school, this bizarre dimension is designated to shelter those who died unwanted deaths. Feeling wronged by God during their earthly lives, the school's residents have decided to form the Afterlife Battlefront—a rebellious faction determined to oppose their god-like student council president, Kanade Angel Tachibana. The group's leader, Yuri Nakamura, recruits Otonashi in their fight against Angel in order to take control of their own lives. However, questioning the morality behind their actions, Otonashi takes a step behind the enemy lines to understand the opposing side of their common fate.

Ichigo Kurosaki is an ordinary high schooler—until his family is attacked by a Hollow, a corrupt spirit that seeks to devour human souls. It is then that he meets a Soul Reaper named Rukia Kuchiki, who gets injured while protecting Ichigo's family from the assailant. To save his family, Ichigo accepts Rukia's offer of taking her powers and becomes a Soul Reaper as a result. However, as Rukia is unable to regain her powers, Ichigo is given the daunting task of hunting down the Hollows that plague their town. However, he is not alone in his fight, as he is later joined by his friends—classmates Orihime Inoue, Yasutora Sado, and Uryuu Ishida—who each have their own unique abilities. As Ichigo and his comrades get used to their new duties and support each other on and off the battlefield, the young Soul Reaper soon learns that the Hollows are not the only real threat to the human world.

When Kazuma Satou died, he was given two choices: pass on to heaven or be revived in a fantasy world. After choosing the new world, the goddess Aqua tasked him with defeating the Demon King, and let him choose any weapon to aid him. Unfortunately, Kazuma chose to bring Aqua herself and has regretted the decision ever since then. Not only is he stuck with a useless deity turned party archpriest, the pair also has to make enough money for living expenses. To add to their problems, their group continued to grow as more problematic adventurers joined their ranks. Their token spellcaster, Megumin, is an explosion magic specialist who can only cast one spell once per day and refuses to learn anything else. There is also their stalwart crusader, Lalatina Ford Darkness Dustiness, a helpless masochist who makes Kazuma look pure in comparison. Kono Subarashii Sekai ni Shukufuku wo! 2 continues to follow Kazuma and the rest of his party through countless more adventures as they struggle to earn money and have to deal with one another's problematic personalities. However, things rarely go as planned, and they are often sidetracked by their own idiotic tendencies.
