In a world where monster invasions are rampant and frequent, being an adventurer in a party is considered one of the most desirable jobs for the honor and fame it provides. Wanting to make a name for himself, a young human warrior named Alvin intends to start his career by completing a low-level request for the guild. While en route, Alvin is confronted by a magical bear and immediately finds himself in a pinch. As luck would have it, a dark elf healer named Karla approaches and asks if Alvin requires assistance—being seemingly oblivious to the situation before her eyes. After a discussion needlessly complicated by Karla's absurdly eccentric personality, Alvin somehow convinces her to help him. Unfortunately, instead of healing him, she accidentally casts a curse: if Alvin strays too far from her, he shall die. Despite being forced to accompany Karla until the curse is broken, Alvin remains steadfast in his ambition to become a full-fledged adventurer. With a partner by his side, the journey toward his goal may grow easier—or harder—depending on Karla's whims.

Megumin is a young and passionate wizard from the Crimson Demon Village, a remote community of mages with red eyes and a flair for the dramatic. She has devoted her life to mastering explosion magic, a powerful but impractical spell that leaves her drained of mana and unable to move for the rest of the day. Regardless, she refuses to learn any other skills. Along with her childhood friend and self-proclaimed rival, Yunyun, Megumin enrolls in the Red Prison: a prestigious academy for Crimson Demon magic users. There, she learns more about the secrets and history of her clan, as well as the threats and challenges they must face. As she polishes her power at the Red Prison with the help of her loyal familiar Chomusuke and her adorable little sister Komekko, Megumin aims to become the greatest explosion wizard of all time!

Shougo Mikadono's father has just passed away, and now he must become the head of Mikadono Group, his father's company. After completing the training to take over, there is just one other stipulation he must adhere to: he will need to find a girl he loves at his new school and marry her by the time he graduates high school. Shougo transfers to Miryuin Private Academy, and it seems like he has many girls to choose from, such as Konoe Suruma, the class representative as well as his first new friend; Miyabi Kannagi, a standoffish but kind girl; Rinka Kunitachi, the student council vice president; Mei Sagara, who runs a cafe and dresses like a witch; and Mana Tendou, the student council president. However, there is a complication: one of them is his long-lost half sister, and he has no idea which one, so how can he become romantically involved with any of them?

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.
