KonoSuba follows Kazuma Satou, a teenage shut-in who dies in an embarrassing accident and is offered a fresh start in a fantasy world that works like a role-playing game, where a Demon King threatens humanity. Allowed to bring one thing with him, he picks the goddess who was mocking him, Aqua. In the starter town of Axel he builds an adventuring party that looks great on paper and falls apart in practice: a useless goddess, a wizard who knows exactly one spell and a crusader who cannot hit anything. Around them gather shopkeepers, rivals, guild staff and the occasional general of the Demon King. This page covers 17 characters, with profiles kept to how each one is introduced, so there are no spoilers for later arcs.
Kazuma Satou 佐藤和真
Kazuma's party · Japanese voice: Jun Fukushima
Kazuma Satou is the main character, a former shut-in gamer who is sent to the fantasy world after his death. Lazy, sarcastic and quick to scheme, he ends up as the reluctant leader of the party. His class, Adventurer, is the weakest one, but very high luck and a sharp mind let him win by picking up odd skills and dirty tricks. Japanese voice: Jun Fukushima.
Aqua アクア
Kazuma's party · Japanese voice: Sora Amamiya
Aqua is the goddess of water who guided Kazuma after his death, until he chose her as the one thing he could take along. Proud, loud and easily brought to tears, she spends her money badly and causes as many problems as she solves. As an Arch Priest she is genuinely strong against undead and great at healing. Japanese voice: Sora Amamiya.
Megumin めぐみん
Kazuma's party · Japanese voice: Rie Takahashi
Megumin is a 14-year-old archwizard of the Crimson Demon clan, a people known for magic and dramatic poses. She loves Explosion magic so much that it is the only spell she has learned. It is hugely powerful, but she can cast it only once a day and then collapses, so someone has to carry her home. Japanese voice: Rie Takahashi.
Darkness ダクネス
Kazuma's party · Japanese voice: Ai Kayano
Darkness is an 18-year-old crusader with enormous defence and terrible aim: she almost never lands a hit with her sword. She joins Kazuma's party eagerly because she wants to stand in front of the worst monsters and soak up the punishment, a quirk the show plays for laughs. Loyal and honourable, she is the party's wall. Japanese voice: Ai Kayano.
Yunyun ゆんゆん
Crimson Demons · Japanese voice: Aki Toyosaki
Yunyun is the daughter of the Crimson Demon clan's chief and a talented wizard who learned many spells, not just one. She calls herself Megumin's rival and keeps challenging her to contests. Painfully shy and desperate for friends, she is easy to talk into almost anything if it means company. Japanese voice: Aki Toyosaki.
Kyouya Mitsurugi 御剣響夜
Japanese voice: Takuya Eguchi
Kyouya Mitsurugi is another person from Japan who was sent to the fantasy world by Aqua. He chose a magic sword, Gram, and became a skilled, admired adventurer who sees himself as a true hero. Shocked at how Aqua is treated, he challenges Kazuma to a duel, which does not go as he planned. Japanese voice: Takuya Eguchi.
Wiz ウィズ
Axel · Japanese voice: Yui Horie
Wiz is a kind, gentle and rather timid woman who runs a magic item shop in Axel. She is also a lich, an undead spellcaster, which makes Aqua furious at first sight. Wiz is a poor businesswoman who keeps stocking items nobody wants to buy, yet she teaches Kazuma useful skills and becomes a reliable friend. Japanese voice: Yui Horie.
Chris クリス
Axel · Japanese voice: Ayaka Suwa
Chris is a cheerful thief and an old friend of Darkness. In the early episodes she teaches Kazuma the Steal skill, which he then uses in ways she did not expect, and the two keep crossing paths after that. Upbeat and quick on her feet, she adds a friendly adventurer outside the main party. Japanese voice: Ayaka Suwa.
Eris エリス
Gods · Japanese voice: Ayaka Suwa
Eris is a goddess known for her kindness and is widely worshipped in the fantasy world, much more than Aqua is, to Aqua's annoyance. Kazuma meets her after one of his deaths in the new world. Calm, polite and gentle, she is everything Aqua is not, which makes the comparison a running joke. Japanese voice: Ayaka Suwa.
Luna ルナ
Axel · Japanese voice: Sayuri Hara
Luna is the receptionist at the Adventurers' Guild in Axel. She registers Kazuma and Aqua when they first arrive, hands out quests and handles rewards, so she meets the party almost every time they want work. Polite and professional, she often has to deal with their messes. Japanese voice: Sayuri Hara.
Dust ダスト
Axel · Japanese voice: Junji Majima
Dust is a rough, lazy adventurer in Axel who first meets Kazuma by mocking his party. After a fun swap of teams, the two become drinking buddies and partners in small-time trouble. He is a delinquent who is always short of money, but he is loyal to his friends. Japanese voice: Junji Majima.
Iris アイリス
Belzerg royal family · Japanese voice: Kanon Takao
Iris is the 12-year-old princess of the kingdom of Belzerg. Well-mannered and very skilled with a sword, she becomes fascinated by Kazuma's adventure stories and starts treating him like an older brother, which worries the people around her. She is a key figure in the later seasons. Japanese voice: Kanon Takao.
Sena セナ
Japanese voice: Hitomi Nabatame
Sena is a strict prosecutor from the kingdom who comes to Axel to investigate Kazuma after an incident that harms a nobleman's property. Serious and suspicious, she watches the party closely and expects the worst from him, which is not always unfair. Japanese voice: Hitomi Nabatame.
Cecily セシリー
Axis Order · Japanese voice: Fairouz Ai
Cecily is a priestess of the Axis Order, the cult that worships Aqua, based in the hot-spring town of Alcanretia. Like every member of the order she pushes conversions on everyone she meets, with no shame at all. She is warm and fun but has very strange priorities. Japanese voice: Fairouz Ai.
Komekko こめっこ
Crimson Demons · Japanese voice: Maria Naganawa
Komekko is Megumin's little sister, a young Crimson Demon who lives in the clan's village. Bold, always hungry and fond of dramatic introductions, she picks up her family's sense of style early. She appears when the party visits the Crimson Demon village. Japanese voice: Maria Naganawa.
Vanir バニル
Demon King's Army · Japanese voice: Masakazu Nishida
Vanir is a devil and one of the Demon King's generals. He can see into people's futures and loves to provoke them; he feeds on the negative feelings he stirs up. Theatrical and polite in a mocking way, he wears a striking mask and sees through everyone, Kazuma included. Japanese voice: Masakazu Nishida.
Verdia ベルディア
Demon King's Army · Japanese voice: Hiroki Yasumoto
Verdia is a dullahan, a headless knight and one of the Demon King's generals. He settles in an abandoned castle near Axel, only to find that a young wizard keeps blasting it with Explosion every day. Annoyed, he goes to confront the town about it. He is one of the party's first big opponents. Japanese voice: Hiroki Yasumoto.
