One of Makoto's work colleagues. Not married. Has many fantasies about women and often says vulgar things making Makoto blush. Okahama himself thought he was good at sex until girl colleagues started to discuss the types of men they hated most. Then it revealed that he had a lot of problems, f.e. thought only about himself.
Makoto's father. A 52-year-old company officer. He is overly sensitive about his sex life, and far too protective of his youngest child, Jun. (source: http://en.wikipedia.org/wiki/Futari_Ecchi)
Makoto's elder brother. A 29-year-old lawyer. He is very nosy and frequently pesters Makoto about his sex life and fancies himself as Makoto's tutor on the topic of pleasuring women. In order to appease his own sex drive, he frequently visits brothels. Is used to speak in an extremely loud voice which (along with the topic Akira usually covers) makes everyone embarrassed.
Kino is the lead character in the story and is described as being around 15 years old with short black hair, large eyes and a fearless face. Kino usually wears a black jacket, brown overcoat, white shirt, goggled cap and wide belt with lots of pouches—using special gear depending on the weather or season as necessary. Kino travels with the motorrad, Hermes. The two have a contract—Kino provides the balance, Hermes provides the speed, and together they can travel anywhere they wish. Kino is an excellent marksman with deadly speed and accuracy, and is typically armed with two large-caliber pistols. On the journeys with Hermes, they both try and stay neutral to the situations they come across and avoid getting into other people's business. It is revealed in episode 4 of the anime and the final chapter of volume 1 of the light novel series that Kino is a female. Her name "Kino" is actually the name of the traveler who saved her as a child and caused her to take to her current lifestyle. Her actual birth name is left unstated throughout both the show and LN but there are implications in the anime that it is "Sakura."
