Frau Koujiro

Frau Koujiro (real name: Kona Furugoori) is one of the main protagonists of the visual novel and anime series Robotics:Notes. She is the creator of Kill-Ballad and the daughter of Minami Furugoori, the director of the anime Gunvarrel. She moves to Tanegashima in search of her missing mother and later joins the Robotic Research Club as the team's programmer to help realize Gunvarrel.

She is voiced by Kaori Nazuka in the Japanese version and Leah Clark in the English version, the latter of whom also voices Mavis Vermilion, Ruby Toujo and Aria H. Kanzaki.

Appearance
Kona has long hair that she typically ties into large pigtails. She is naturally a brunette, but opts to dye her hair blonde. Kona has a noticeably thin physique, largely attributed to her obsessive nature which causes her to neglect eating for extensive periods of time. She is also quite pale, likely a side effect of hoarding herself indoors under perpetually low-temperature air conditioning.

While in the privacy of her room, Kona leaves her hair down and wears a simple, white tank top with comfortable shorts.

Personality
Kona is a very anti-social person; she prefers to stay alone in the comforts of her apartment and heavily invest her time online either for Kill-Ballad or searching for clues on her missing mother. As a result, Kona lacks even the most basic social etiquettes, stutters heavily when she speaks, frequently speaks in SMS language (e.g. fwiw, which stands for 'for what it's worth') and references Japanese memes. Kona is a dedicated fan of the anime Gunvarrel, which her mother helped produce, and does not take kindly to those who speak poorly of her mother's legacy.

One of Kona's most prominent characteristics is her blatant pervertedness. Spending much of her time playing eroge and yaoi dating sims rather than interacting with real people, Kona's mind is a twisted, convoluted mess of perverted, borderline psychotic thoughts. She is also quite volatile, frequently and rapidly switching between bored aloofness and erratic excitement.

Both a strength and weakness of Kona's is her tendency to easily become obsessive. Once she is consumed in a project, she will not stop until it is complete and, while efficient, she often forgets to sleep and eat during these phases, forcing Kaito to often bring food whenever he visits her. Kona is also a slob and her room is a perpetual mess.

Skills & Abilities
Despite her quirks, Kona is a brilliant computer programmer; she is highly skilled at game creation as well as hacking into other people's networked systems. She was also able to develop functioning A.I. characters of Gunvarrel's protagonists, Yuuki Rosetta and Genki Dotou.
