Countess Isabella Montovani is the grandmother of Angeletta. Her son, Count Adolfo, who fell in love with a commoner named Giovanna, was Angeletta's biological father. She used to be called "Ice Queen" because she used to have a very cold personality. Lady Isabella entrusted the infant Angeletta to Marchelo Rossi during an unseasonable springtime snowfall. She became the benefactor of Angeletta during her entire years with Rossi's family. It took several years before the countess accepted her granddaughter. Lady Isabella used to believe that Angeletta was only after the Montovani estate, but with the help of Romeo and the rest of the members of the Black Brothers, she was enlightened. In the end, Countess Montovani took custody of Angeletta. She brought her granddaughter to Paris to be treated for her serious heart illness. She reappears later to help the siblings Alfredo and Bianca Martini reclaim their inheritance and clear their tarnished names. She also attended Alfredo Martini's funeral.
Akane is one of Makoto's three older sisters and a make-up artist, though still technically a student. She's 22 years old and the first one to know about Makoto's secret relationship with Ito. Akane is very nice and helps them out whenever she can. She appears to like Ito a lot, and she looks almost exactly like Makoto (though she cut her hair about halfway through the first volume). Out of his entire family, Akane seems to be the most supportive of Makoto's decision to become an actor, and she also helps him a lot when he's in trouble (i.e: brings him clothes, make-up, or costumes when he needs it and helps him pick out girl clothes). It was in fact Akane who inspired Makoto to become an actor when she snuck him out of the house after a frustrating argument with his father to see a local play. Thanks to her talents Makoto can easily pass as a girl all through high school; she even taught him how to do his makeup and everything without her. Although she is a quiet and naturally formal type of person, she is also observant and wise. Eventually she meets Ito's brother Yûto, and the two hit it off very well. Though the name Akane has a variety of different spellings, it means "madder," a flower, which corresponds to her two sisters' names. (from wikipedia)

Not much is known about Romero, but he and his buddy Dario Nicolodi are followers of Janus Cascade, and the three of them journey the wasteland together.

Mutio is a water creature created by Zorndyke. Her species is often referred to as the nereids (not to be confused with the mythological Nereids of ancient Greece). Due to their internal organ structure and design, they cannot speak, but each has a very high level of intelligence. The nerieds are Zorndyke's ultimate Unigumo pilots. They live in shallow areas of the ocean and are programmed for strict obedience, even to the point of suppressing their own feelings. Mutio is saved by Hayami early in the series when her fighter crashes and she almost dies. This confuses her due to Hayami being "the enemy." In return, she later saves Hayami when he is in trouble. She also cares for him, and feeds him when he is stranded at one point.
Alfredo, the founder and first leader of the Black Brothers, was Romeo's best friend. Born into a noble family, he was the only son of the couple Viscount Vittorio and Viscountess Patrizia Martini and the older brother of Bianca. Alfredo loved to read books. He and his sister Bianca grew up at the Martini mansion in Piedmont. Together they enjoyed a happy, peaceful life with their parents until a terrible tragedy struck their family. The siblings' relatives Maurizio and Grazela Martini coveted all the treasures of Vittorio, especially the Martini medal. Their deep enviousness led them to burn the Martini mansion. Alfredo and Bianca's parents were killed during the incident, but before they died, Viscount Vittorio managed to entrust the Martini medal to Alfredo. The siblings escaped from the fire, bringing with them the medal. Maurizio and Grazela hunted the orphaned siblings for the medal. They even put on Alfredo and Bianca's heads the blame for the tragedy in Piedmont, making them wanted by the police. A month after the burning of the Martini mansion, Alfredo and Bianca stumbled across a farm village. During this time, Alfredo's sister could no longer walk because of tiredness and because of this, they rested along the road. They were later found and rescued by a farmer. After the siblings' rescue, Luini, the "God of Death," appeared in the farm village. Alfredo then decided to sign a contract with Luini and go to Milan to work as a chimney sweep in order to protect Bianca. Alfredo embarked on a long journey to Milan, leaving behind his beloved younger sister in the farm village. It was during his journey to Milan that Alfredo first met Romeo, who at that time was mistakenly accused of stealing apples by a vendor named Tonio. The noble boy saved Romeo by showing and telling Tonio the proofs of Romeo's innocence. Alfredo and Romeo's friendship began then. Together they were sold in Milan by the "God of Death" to their respective bosses. Alfredo was bought by a very cruel man named Citron. Before Alfredo and Romeo separated, they swore eternal friendship and promised to each other that they would meet again. Alfredo experienced starvation and violence while he was living with Citron. There were days that he did not eat because the money that were supposed to be used in buying potatoes were wasted by his boss in buying liquors. There was also a time that Citron threw a bottle and a plate at him while cleaning the floor in their home. Alfredo and Romeo later reunited. During the reunion, Alfredo revealed to Romeo his intention to create a fraternity for chimney sweeps that can help each other in times of need. They joined forces with other chimney sweeps in Milan and the Black Brothers was formed. All of the members of the alliance chose Alfredo to become their leader. As a leader of the Black Brothers, he was respected and admired by all of his companions for his intelligence and bravery. The Black Brothers victoriously defeated the Wolf Pack in their fights twice. First, at San Babila Church and finally at Sempione Park. The Black Brothers under Alfredo's leadership was also instrumental to Countess Isabella Montovani's acceptance of Angeletta as her granddaughter. Alfredo's sister Bianca was captured by Maurizio and Grazela Martini and together they went to Milan. Knowing that Alfredo was in Milan and that the Martini medal was with him, the evil couple took Bianca hostage to get by force the medal from him. Romeo and the Black Brothers then saved Bianca from her evil relatives and brought her to San Babila Church, where she was reunited with Alfredo. During the reunion, Alfredo coughed blood and suddenly collapsed. He was brought to Dr. Casella and the doctor diagnosed that he had tuberculosis. Although the name of the disease was not mentioned to Alfredo, he was still aware about his terrible fate. Sensing that he could die anytime, Alfredo decided to entrust his only sister to Dr. Casella. He even decided to meet with the King of Italy to clear his and Bianca's tarnished names and to reclaim their inheritance. With the help of the Black Brothers, the Wolf Pack and Countess Montovani, the Martini siblings successfully met the king who was attending a banquet during that time. In the end, Alfredo proved to the King of Italy that he was really part of the Martini line by showing his father's medal with a "mark of benediction" from the king's father, Carlo Alberto of Sardinia. The king was also convinced that the Martini siblings truly did not kill their own parents. The following day after the victorious meeting with the King of Italy, Alfredo died of tuberculosis. He died in the arms of his best friend Romeo. His death was mourned by all those who love him, especially Bianca, Romeo and the other living members of the Black Brothers. Romeo succeeded his late best friend as leader of the Black Brothers. The first thing that Romeo did as the new leader was to start a fundraising for Alfredo's funeral. The fundraising was successful. Alfredo was given a solemn funeral. In front of Alfredo's grave, the Black Brothers and the Wolf Pack made peace with each other. Alfredo is the namesake of the son of Romeo and Bianca.

Giovanni is the leader of the Wolf Pack gang. He is fair when it comes to fighting. This was proven when Giovanni and his companions fought with the Black Brothers. Before their fight began, he told everybody that using any kind of weapon is not allowed. But Tachioni, one of the members of the Wolf Pack, disobeyed. He drew a blade and tried to kill Romeo. Because of this, Giovanni accepted the defeat of the Wolf Pack gang in their fight against the Black Brothers. Later on in the series, Giovanni and his companions became more supportive for the Black Brothers. In the last episode of the anime, Giovanni and the rest of the members of the Wolf Pack gang decided to make peace with the Black Brothers.
