Kazuma Satou

The protagonist of this work, an adventurer who was reincarnated into another world after his death. In the story, he is often referred to by the katakana for Kazuma. His age in the story is 16 to 17 years old (20 years old in the web version). Visually, in illustrations and anime, he has green eyes and short brown hair.

He doesn't hesitate to use underhanded methods to win, takes pleasure in doing things his opponents dislike, and often shows a mean-spirited smile when gaining the upper hand in battles. He also frequently exhibits lecherous behavior. However, fundamentally, he is a good-natured person who never abandons his friends and cannot ignore someone in trouble in front of him. Because of this, while he is intensely disliked by some, he is generally trusted by his companions like Aqua.

Initially, he wore the tracksuit he had on at the time of his transfer to the other world as his everyday clothes, but later switched to lighter, more adventurer-like gear.

Before his reincarnation, he was a Japanese high school student. He became a shut-in NEET just before his reincarnation, after being shocked to see his first love riding on the back of a delinquent senior's motorcycle in the summer of his third year in middle school. Aqua continuously calls him a "shut-in NEET."

His cause of death was cardiac arrest. One day, while out shopping, he mistakenly thought a high school girl was about to be run over by a truck, pushed her out of the way, and died from the shock of mistakenly believing he had been run over.

After his death, he was offered a chance to go to another world by Aqua, the water goddess in charge of his reincarnation. He chose Aqua as a special privilege to take with him to the other world, and landed in the town of Axel. There, he formed a party with Aqua, Megumin, and Darkness, consisting of three high-class and one low-class adventurer, and became involved in various incidents in the town of Axel.

In combat, he mainly uses skills like Thief (Steal, Sneak, Enemy Detection) and Archer (Clairvoyance, Sniping), as well as Lich (Drain Touch), providing precise instructions and support to other members, and also uses bows, swords, and basic magic himself.

In every major turmoil involving the members, he initially reluctantly stands up for his friends, spurred on by those around him, and ends up declaring, "Can't be helped, huh!" in a half-resigned, half-self-scolding manner, which has become one of Kazuma's signature phrases.

In the Kadokawa Sneaker Bunko official site TV anime adaptation commemorative character popularity poll, he ranked 8th. In the "This Light Novel is Amazing!" male character category, he ranked 8th in the 2017 edition, 9th in both the 2018 and 2019 editions, 6th in the 2020 edition, and 8th in the 2021 edition.
