Kazuma Satou

Voiced by: Ryōta Ōsaka (drama CD),^[1] Jun Fukushima^[2] (Japanese); Arnie Pantoja (English).^[3]

Kazuma is the protagonist of Kono Subarashii Sekai ni Shukufuku wo!, a 17-year-old game-obsessed shut-in, becoming one with his bedroom after having his heart broken by his childhood friend in middle school.^{LN 5.2.2} While returning home from buying a video game, he attempts to save a classmate from being hit by a slow-moving tractor he mistakes for a speeding truck, and dies from acute stress reaction. As a result, he is sent to a fantasy reality and becomes a role-playing game character.^{LN 1.P} He has average stats in crucial categories, but above average intelligence and extremely high luck, neither of which are important for adventurers.^{LN 1.1.1} Regardless, he becomes one and learns basic skills such as steal, archery, monster detection, and basic magic. Because he never chooses a class, Kazuma is referred to as an "Adventurer" and is able to learn foundational abilities and spells that would otherwise be exclusive to a single class, and learns to overcome the limitations of his classless status by combining skills and spells in unexpected ways. Kazuma lusts on almost all the females he sees, except Aqua, who he acknowledges as attractive but cannot get excited by, even after months of staring at her in her pajamas and smelling her hair while she sleeps. He is initially seen as just perverted and hopeless by his female companions, but as time passes he proves to be reliable and useful when the situation calls for it. Megumin and Darkness eventually fall in love with him. Kazuma finds Darkness extremely attractive but her personality turns him off, and while he sees Megumin only as a child at the start of the series, as time passes he starts to find her attractive as well. He eventually accepts her love confession, entering a state of "more than friends, less than lovers". Kazuma rejects Darkness when she confesses to him, but that has not stopped her from trying to seduce him, even stealing his first kiss and forcing herself onto him to win over his affection. Megumin and Kazuma share a passionate french kiss while trying to have intercourse, before the battle against the Devil King, but a running gag in the later light novels is that every time they are about to get intimate they are interrupted. Megumin promised Kazuma to give him "something incredible" once they returned home after defeating the Devil King.
