Yoshida Ayumi is a student in Teitan Elementary when Shinichi was enlisted into her class after he had been shrunk by the drug APTX 4869. Shortly afterwards, Ayumi and her classmate Genta had the idea of investigating an apparently haunted mansion. They persuaded Conan to come along, and Genta also personally drafted Mitsuhiko when the latter expressed his criticism about supernatural hauntings. As it turned out, the haunting served as a cover-up for an old homicide case. Following its resolution, the foursome decided to stay together and form the nucleus of what would become the Detective Boys. For a time, Ayumi was the sole female member of the Detective Boys until Haibara joined the group. During a case involving a cache of stolen Italian gold coins just prior to the official formation of the Detective Boys, Conan saved the group from getting killed by the Mafioso who were also after the gold, earning Ayumi's gratitude which quickly developed into a serious crush. Ayumi is a naive and innocent little girl who shows courage from time to time and acts as the team's cheerful spirit. She has an open crush on Conan, which makes him uncomfortable, though Ayumi thinks that he has feelings for Haibara because he tries to protect her and she often sees them talking amongst themselves in private. Ayumi later becomes better friends with Haibara, and she allows Ayumi to use the more informal term Ai-"chan" to address her. When on a case, Ayumi often makes really simple observations that allows its progress and resolution. For instance, she unlocked one of the codes from the Momotaro container the Detective Boys found in Kurashiki by deducing that it was most likely referring to one of the statues at the Oohara Art Museum: they had to walk 25 steps from the statue towards the direction it was facing.
Nodoka is Ranma's loving mother. She hasn't seen him and Genma in over a decade though, when they left on their training trip. Stating that a doting mother would hinder Ranma's training, Genma made a contract with her to raise Ranma as "man amongst men", and if he failed, he and Ranma were to commit seppuku. However, because Ranma's curse makes him a woman half the time, they spent most of Nodoka's appearances hiding from her as Ranko Tendo and her pet, Mr. Panda. Nodoka's heart was constantly broken by knowing that she wanted nothing more than to see her son again. Eventually in the manga, she did meet Ranma and Genma and discovers their curses. However, she was more accepting than they expected. Mostly because she eventually began to suspect that Ranma and Ranko were, in fact, the same person. (Wikipedia)
Aruruu is very shy and overall quiet. Like Eruruu, her name is taken from a fictional flower, saying that the Eruruu and Aruruu flowers grow together. After Mutikapa, a large, white tiger that is nearly invulnerable to small weapons, is defeated by Hakuoro, she tends to her baby tiger whom she names Mukkuru. Mukkuru grows in a very short time and becomes Aruruu's mount in battle. Aruruu is Eruruu's younger sister.
Oboro was in the beginning an impulsive and somewhat egotistical bandit chief of a fort near the village of Yamayura. He is very caring for his younger sister, Yuzuha, to whom he would bring Tusukuru to oversee her health. When Hakuoro becomes the leader of the country's rebellion, Oboro joins forces with him and swears eternal allegiance, with revenge for Tusukuru among his reasons, calling Hakuoro his brother. His "vassals", Dorii and Guraa, are always at his side, though their lord/ vassal relationship is never explained. After the rebellion, Oboro becomes a general of the new country of Tusukuru, and leads a sort of "special forces" unit of vagabond swordsmen from his old bandit fort. He is constantly butting heads with Kurou over military matters, and it becomes a source of comic relief. At mealtimes, Oboro hates eating vegetables with a passion, to the point where eating a small amount causes him to gag. Oboro's main weapons of choice are two katanas that he uses in balance with his good agility, making him a deadly fighter but quite inexperienced compared to the other main and supporting characters. Just before Hakuoro is sealed into a deep sleep, he names Oboro as the next emperor of Tusukuru. When Yuzuha passes away a short time later, Oboro goes on a journey of self-discovery across the lands to figure out how to be a good emperor, with Dorii and Guraa ever at his side. In the PC game, Oboro still goes on a journey, but to show of his sister Yuzuha's child that she received by virtue of Hakuoro's divine blood.
Dorii and Guraa are twin archers serving under Oboro. They are talented archers and often lead archer groups in Hakuoro's army. There are few ways to tell them apart. For one, Dorii has purple eyes while Guraa's are blue. Also, the bottom part of Dorii's clothes are blue while with Guraa they are red. You really can't make them separate characters since they're always side by side. They are somewhat androgynous, and as such their gender is difficult to ascertain, even by other characters. In the game, they reveal they are male, whereas in the anime they are left androgynous.
Second year student at Kitanohashi High School and a new member of the Magic Club. Sae is eager to learn magic, but often has setbacks due to her clumsy nature. She looks up to Takakura as a great mentor. Although she actually has feelings for him beyond that, she is too shy to express them. Of the five members, Sae has the greatest amount of power to utilize, but lacks the training and concentration to fully tap into this potential. Sae displays a clear ineptitude to flying on a broomstick in the OVA series, but her skills progress and by the TV series, she can fly on different pole-sized items without any problems, even without using her wand.
