Setsuna is a Shinmeiryu swordswoman from Kyoto who was taken in by Eishun Konoe, Konoka's father and the leader of the Kyoto Mage Association. She is childhood friends with Konoka and her protector. Setsuna spends the beginning of the series being relatively cold to Konoka, wishing to protect her from the shadows due to not forgiving herself for being unable to save Konoka when she almost drowned when they were kids. She does eventually open up to Konoka after the Kyoto arc and begins calling her "Oujo-sama" and "Kono-chan". Setsuna's pactio, Sica Shishikushiro is a wakizashi which she can summon and multiply at will to strike targets like missiles. Due to her training she's also skilled in anti-demon arts and is the one who taught Negi how to create shikigami from paper. Setsuna is a hanyou like Koutaro, in particular a crow. She was expelled from her people because white wings are considered a bad omen, and it was implied by Evangeline that she is an albino using hair dye and contact lenses to appear human. A running gag within the series is that Setsuna and Konoka appear to have romantic feelings for one another, yet Setsuna will deny it whenever she and Konoka are stumbled upon in romantic situations or asked about her preference.
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."

Two young sisters who took refuge at the Crimson Scholar's estate. Coming from a serf family of seven siblings, the sisters' other siblings died from hunger and disease. Due the harsh life of serfdom which their lord treated them like slaves, they escaped and hope to get a better life at the city. However, Chief Maid looks down on the sisters since their presence would bring trouble with the Crimson Scholar. Furthermore, she considers them "bugs" for allowing life harsh realities to control their fate rather than overcoming it and control their own lives as human beings and not thinking and planning their future. Upon asking the Chief Maid to teach them to become proper humans, they are taken unto her guard, working as assistant maids. Thanks to the education given to them, Big Sister Maid becomes knowledgeable about the different lives and social classes of human society while Little Sister Maid becomes an expert with food and drinks. Contrary to the knowledge of Hero and the others, they do not know the Crimson Scholar's secret.
Momotaros (モモタãƒã‚¹, Momotarosu?) is the first Imagin that gives Ryotaro his power, which allows for the Sword Form transformation. He can also sense when an Imagin is rampaging in the city, subsequently alerting Ryotaro immediately. His natural weapon as an Imagin is a sword named the Momotarosword (モモタãƒã‚¹ã‚©ãƒ¼ãƒ‰, MomotaroswÅ�do?). Momotaros blames Ryotaro for his Oni-like form, though it matches his personality, best described as hot blooded, arrogant, and comedic, serving as a foil to Ryotaro's own shy and cowardly personality. In fact, Momotaros is more interested in fighting than carrying out the Imagin's goal. Unfortunately, he is constantly beaten by Hana when he gets Ryotaro into trouble. When he possesses Ryotaro, declaring the words "Here I come!" (俺ã€�å�‚上ï¼�, Ore, sanjÅ�!?)[1], Momotaros's own personality takes over, giving Ryotaro power, confidence, and a bit of his eagerness for a good fight. His eagerness is shown in battle, where he always declares the words, "I am, from start (to finish), at the climax!" (俺ã�¯æœ€åˆ�ã�‹ã‚‰ï¼ˆæœ€å¾Œã�¾ã�§ï¼‰ã‚¯ãƒ©ã‚¤ãƒžãƒƒã‚¯ã‚¹ã� ã�œï¼�, Ore wa saisho kara (saigo made) kuraimakkusu da ze!?). Momotaros is also somewhat selfish, initially fighting alongside Ryotaro in order to ensure his own survival. Though he unknowingly places Ryotaro in unneeded danger to suit his fancy, Momotaros eventually learns to respect him and his desire to protect others. Though he demands respect, Momotaros is usually put in his place by Hana and her powerful punches. He also does not know how to swim, has a narcotic reaction to red peppers, and seems to be afraid of dogs. While he acts hostile and demeaning to the other TarÅ�s, he does care about them, proven by hiding his anguish while they are slowly disappearing due to the events of the Climax Scene. Momotaros is the base for Den-O's Climax Form, as he has control of the head and torso and can control the other sections that the other TarÅ�s usually have primary control of if need be. However, due to the newly-formed Junction Point, Momotaros's synch with Ryotaro is negated. However, his power is now accessed in the DenKamen Sword's Momo-Sword Mode. Since then, Momotaros makes it his task to train Ryotaro to fight on his own, being evasive on his reasons for it. But once Ryotaro learns the truth, both he and Momotaros have a falling out. Momotaros, enraged at Ryotaro for his decision to fight without the TarÅ�s, fights Den-O Plat Form to test if Ryotaro can really back up his words. After Ryotaro divulges his resolve, Momotaros apologizes to him for being evasive about the recent events and the two went on to destroy the Armadillo Imagin with the other TarÅ�s at their side. On his own, Momotaros can perform his style of Den-O's Extreme Slash, referred as "My Finishing Attack, Momotaros Version" (俺ã�®å¿…殺技モモタãƒã‚¹ãƒ�ージョン, Ore no hissatsu waza Momotarosu BÄ�jon).
Princess Peach is the ruler of the Mushroom Kingdom. She is often captured by Bowser in his attempt to take over as King.
Hermes is a Brough Superior motorrad (a two-wheeled vehicle that cannot fly but moves in the direction it's pointed—in other words, a motorcycle) who travels around with Kino. Hermes provides the speed that allows them to go anywhere they wish. Aside from his speed and capacity for toting about large amounts of luggage (Kino never seems to travel light), Hermes doesn't really have many other qualities except for constantly mixing up quotes and complaining. He is also rather gullible, trusting Kino absolutely even when Kino is teasing him, which leads him to grumble and complain some more. Perhaps his most famous line is "I'm bored." The motorrad is in many ways naive and innocent, and acts very child-like, which tends to be a sharp contrast to Kino's more mature and worldly bearing. Still, Hermes is quite reliable and makes a good companion for long trips. In the Gakuen Kino off-shot series, he takes the form of a cell phone strap instead. (Source: kino.ming-ling.net)
