Hermes is a talking motorad who travels with Kino to various countries and lands.
Hermes is often pessimistically realist, unbiased, and usually comes across as the comic relief character. He has a tendency to complain, which sometimes annoys Kino. Despite this, he is a very reliable companion both mentally and physically, as he is the only person who Kino can speak with about her innermost thoughts. He is naive and innocent in many ways, often believing things that are only meant as a joke. He also has a habit of trying to state famous quotes, but usually forgets or changes a part, prompting Kino to correct him. Although Hermes can be interpreted as a caring companion towards Kino, Hermes however does not care whoever his rider is. His sole purpose is to provide speed while a rider provides him with a direction and balance. If Kino were to be killed, he would have to wait for an extended period of time before another traveler utilizes him as a mode of transportation. Kino is well aware of Hermes's purpose as a motorrad and therefore fiercely protects him from anybody attempting to steal or damage Hermes as well as herself in order for Hermes to continue having a rider.
Hermes is also extremely intelligent in literal data. He can assess physical situations to an extremely complex degree but is annoyingly vague in expressing it. In the anime, he uses his knowledge to assess a mythical flying machine was indeed able to fly provided with sufficient thrust.
Hermes was found broken in an alley by the original Kino during his stay in the Land of Adults. The original Kino and the then eleven-year-old Kino (whose name was not Kino at the time) fixed him, although at the time Hermes could not talk to them. They decided to give him the name Hermes, after Kino's (original) previous motorrad.
After the original Kino is killed, Kino uses Hermes to escape the Land of Adults, and they keep riding until they collapse into a field filled with flowers. Hermes calls her Kino, believing that to be her name, and she decides to accept the new name to honor her savior's death.
Kino- All riders and motorrads have an understood agreement between them- the motorrad provides the speed, the rider provides the balance, and together they can go anywhere they want. However, their friendship is much deeper than that. He has absolute trust in Kino and her abilities, although that does not stop him from worrying about her. Kino fully trusts him in turn, and they have grown closer over their travels. Whenever Kino needs someone to talk to, Hermes is always there for her.
Hermes is a Brough Superior SS100. It is not known which exact model of SS100 he is. Brough Superior SS100's are one of the most collectible motorcycles as less than 350 survive to this day. The SS100 was an icon of the consumer motorrad market in the early 20th century as each SS100 was guaranteed to reach 100mph and was the first production motorcycle to reach such speeds. It remains an iconic feat of engineering in the motorcycling industry even to this day.
- Engine sounds from a vintage Brough Superior SS100 were recorded to make Hermes' engine sounds in the anime.
- In "Gakuen Kino," Hermes is a cell phone strap. He is described as two canvas strips connected by a brass buckle with a Brough Superior SS100 engraved into the buckle. His personality does not change.
