Yasuna Oribe (折部 やすな, Oribe Yasuna)

Voiced by: Chinatsu Akasaki (Japanese); Hilary Haag (English)^[2]

A normal high school girl and self proclaimed friend of Sonya, who is often friendly to Sonya despite how dangerous she is. She tends to take on the brunt of Sonya's attacks whenever she takes her by surprise or goes overboard with her pranks. She is quite simple minded and is not afraid of Sonya at all, despite the fact that she is an assassin.

Sonya (ソーニャ, Sōnya)

Voiced by: Mutsumi Tamura (Japanese); Luci Christian (English)^[2]

A foreign trained assassin attending a regular high school. As she constantly takes on assassin work she is constantly alert and often attacks Yasuna when she takes her by surprise or tries to play jokes on her. Despite her tough composure, she is scared of various things such as cockroaches, ghosts, and dogs (even domestic dogs). She also has been shown to care a little for Yasuna.

Agiri Goshiki (ごしき あぎり, Goshiki Agiri)

Voiced by: Ai Takabe (anime), Minami Shinoda (Kirara Fantasia)^[3] (Japanese); Rozie Curtis (English)^[2]

A laid back ninja from the same organization as Sonya. She transferred to Sonya's school for some assignments and stays at a former ninja club room without permission. She often perplexes Sonya and Yasuna with dubious 'ninjutsus'. She is shown to be calm and have long purplish hair.

Unused Character (没キャラ, Botsu-kyara)

Voiced by: Rie Kugimiya (Japanese); Brittney Karbowski (English)^[2]

A redheaded, green-eyed, nameless character who was supposed to be part of the main cast, but was dropped as Yasuna had supposedly taken on all her personality traits. She has since vowed revenge against Yasuna and Sonya.

Theron Martin of Anime News Network found some of the humor repetitious and the mediocre animation as the series' faults but said that it was balanced out with material that did garner laughs and a workmanlike dub, calling it "a series probably best-enjoyed one or two episodes at a time; trying to marathon it can be a brain-melting experience and is so not recommended. Keep it to smaller doses, though, and it delivers often enough to make a reliable comedy diversion."^[2] Aiden Foote, writing for the Anime Reviews, also found the animation middling but praised the slapstick humor and its delivery by both Yasuna and Sonya, concluding that "Overall, almost from nothing, Kill Me Baby! seems to have itself a sweet little niche in the congested four-panel market. What it lacks in a large cast, it makes up for by diligently bringing the characters it does use to life."^[13]
