Okabe is a melodramatic, eccentric and rarely tsundere* individual. He is a self-proclaimed mad scientist, who likes to assume his "true name" "Kyouma Hououin" (Hououin Kyouma), and often uses this to introduce himself to others. For the most part, people do not seem to care and instead address him by his actual name or by 'Okarin' (his nickname)
Kurisu is generally a sensible, serious mature young woman, usually calm and collected even when someone is acting tense in front of her. However, she can also show a much more timid side at times. She is shown frequently to hate being nicknamed, as she dislikes all of the names that Okabe gives her, with 'The Zombie' bugging her most of all. Ironically, on the rare occasions Okabe uses her real name, she takes it as a sign that something is seriously wrong. Kurisu is also practical and a realist
Also known by his nickname Daru, his online handle DaSH ("Daru the Super Hacker"), and Barrel Titor, is an experienced hacker and a hardcore otaku. Daru is obsessed and extremely talented with programs and computers, capable of hacking into the mainframes of top-secret organizations and processing complex computer codes.
Also known as Mayushi, is Rintaro Okabe's childhood friend. Mayuri possesses an extremely childish and naïve attitude for her age. While this may have something to do with her inability to accept the death of her grandmother when she was young, Okabe states at one point that she's always been a little bit different, though he never goes into any detail beyond this.
Suzuha Amane (Amane Suzuha), later known as Suzu Hashida, is a part-time employee for Yugo Tennouji, the landlord of Rintaro's flat and is on a search for her father in Akihabara. She enjoys riding her bicycle and appears to be at odds with Kurisu and a major character in the series. A friendly, athletic girl who loves cycling. Suzuha often comes across as overly familiar, but in truth she maintains a carefully measured distance from everyone. When something captures her interest, however, Suzuha's personality changes dramatically and she becomes aggressive and relentless, meaning she is a really straight type of person.
Urushibara Luka (Usually called Ruka) is a close friend of Mayuri Shiina and so-called protégé of Rintaro Okabe. While feminine in appearance and personality, Luka is a male in most world lines. Mayuri Shiina is his classmate. Luka is very sensitive and emotional. Even simple, sudden responses from Rintaro can cause him to cry or tremble. He likes to wear girly clothing, which caused Kurisu to confuse him for a real girl when the two met in Rintaro's lab. Rintaro describes him as "More girly than any girl, more feminine than any female."
Moeka Kiryu is a part-time editor whom Okabe encounters in Akiba. She is practically glued to her phone and cannot function without it. Even when face to face, Moeka prefers to communicate by email, to the point where if her phone is taken away, she will almost refuse to speak until her phone is returned. Personality wise, Moeka is quiet, absent-minded, reserved, has difficulties interacting with people, and seen to be expressionless most of the time without actually reacting towards anyone or anything, except for certain situations; her preferred form of communication is via text messages even if the person she is "talking" to is right in front of her. Therefore, Moeka is very protective of her phone and becomes agitated if someone tries to take it from her hands.
