Author's Note: Okay, remember what I said about giving this story a bonus chapter and I cancelled it afterwards? Well, I had in mind that maybe I should just do a shortcut on that bonus chapter to avoid consuming the time and the sweat. So instead of making a very- very- very long bonus chapter, I've decided to make an OC-profile before you guys jump to the updated chapter…..
Name: Rokudo Shichirou
Title: Ninth Estraneo Sky boss
Blood type: unknown
Age: 16
Dying will flame/s: sky, mist
Weapon: Serpent Scepter
Character Summary: Estraneo family's Ninth sky boss and Mukuro's long-lost elder twin-brother. Like Mukuro and his subordinates, Shichirou was also experimented while he and his brother were still in a very young age. After the surgeons and scientists have accomplished their tests no him, his parents hid him back home to their mansion secretly while Mukuro was left behind next for the experimentation. Mukuro, having thought that the scientists killed Shichirou, destroyed the entire laboratory unit and executed every worker of the base including his parents, meeting Joshima Ken and Kakimoto Chikusa after his success. Shichirou over-heard about Mukuro's resistance against the Estraneos including his fault of murdering their parents. He sworn vengeance for his parents towards his brother, rebuilding the Estraneo famiglia unnoticed and became its next blood-lined leader. Ten years later after Mukuro's defeat in challenging a candidate for Vongola's tenth Sky boss (namely Sawada Tsunayoshi), Mukuro was told about Shichirou's existence by one of the prisoners of the Vendice (unknowingly to Mukuro, these prisoners who have told him about his brother's existence are the murderers who killed Chrome's real father. They were imprisoned by the Vendice guards after they were captured by Yuuto Hiroshi.). Soon after Vongola's encounter with the Shimon famiglia, Shichirou finally made a move for his revenge, ordering his men to kidnap Mukuro, his subordinates, and his vessel. He was soon informed about Vongola's cloud guardian, Hibari Kyouya, being the temporary guard and protector of Mukuro's vessel. Having knowledge about his blood-lusting attitude, he commanded Rosso Calibri to take in Vongola's cloud guardian with Chrome Dokuro back to Italy. Once they have arrived, he asked him to turn back against Mafia's leader-family and join the Estraneos, in exchange for his freedom to execute Mukuro and his underlings. Hibari refused immediately and was unexpectedly afterwards saved by Mukuro, who have successfully broke out from a cell he was being kept on by his brother. Shichirou then turned his attention to making Chrome his bride to grab both Mukuro and Hibari's wrath to run back to her and lead them into a trap.
Personality: Shichirou and Mukuro shared the same laugh of amusement towards common and uncommon people. Both brothers are quite similar with each other, except of course for their eyes and their bangs (Shichirou's are longer then Mukuro's). However for the record, Shichirou is more spoiled, egoistic, and evil-minded than his brother, which makes Mukuro rather irritated. He has a soft spot for women like Nagi and Rosso. The only difference that both brothers have is that Shichirou never treated his subordinates as mere toys and tools. Unlike Mukuro, Shichirou cherished his underlings and loved his parents even though they were quite abusive. He's also the first person who calls Hibari "Cloud" because of his dying-will flame.
Name: Yuuto Hiroshi
Title: Ninth Estraneo mist guardian
Blood type: unknown
Age: 16
Dying will flame: mist
Weapon: crossed spear
Character Summary: Estraneo family's Ninth mist guardian, Shichirou's right-hand-man, and Chrome's long-lost elder brother. His father, Noboru Yuuto, was one of the greatest hitmen who ever lived in the world of Mafia and is quite a close comrade to Reborn. As said by his mother, Hanagara Mizumi, Hiroshi was able to inherit his father's appearance, mannerism, strength and even his title. During his childhood years, Hiroshi was taken away from Nagi and Mizumi by Noboru's enemies' days after their father's death. However, Shichirou and a few of his subordinates saved him from the assassins as soon as he was taken to Italy. In return for Shichirou's service, Hiroshi joined the Estraneos and became Shichirou's trustworthy right-hand-man. Ten years later, Hiroshi followed his father's footsteps and has also become Mafia's greatest hitman that he was even able to capture the assassins who murdered his father. The Vendice was able to hand Hiroshi their trust when he gave the permission of punishment for the murderers of his father to the law-keepers. As soon as Shichirou was informed about the Vendice's faith towards Hiroshi, he ordered him to kidnap Mukuro Rokudo out of his tank. Hiroshi followed and did well on his mission that the Vendice wasn't aware that it was he who took out Mukuro from prison. Soon afterwards, Shichirou then finally gave another order to Hiroshi and Rosso to bring Nagi Hanagara to Italy along with Hibari Kyouya. In return for accepting his boss to marry his sister, Shichirou gave his signal and allowed Hiroshi to avenge his sister and murder Mukuro instead of Hibari
Personality: Hiroshi is very serious when it comes to missions and other family affiliations. He gives his best for every assignment he does for the Estraneos, earning the right to become Shichirou's second-in-command. But he turns his joker-side on whenever his hands are free from assignments. Many of Noboru's missions in the past included flirting with women, which may have been the reason why Hiroshi has a perverted attitude towards Ross. Though their relationship maybe somewhat described as a love-bird manner, it is still unknown whether they're in love with each other or is it just simply for fun.
Name: Maria Rosso Calibri
Title: Ninth Estraneo lightning guardian
Blood type: O
Age: 15
Dying will flame/s: storm, lightning
Weapon: metal chains
Character Summary: Estraneo family's ninth lightning guardian and is also unknowingly a student of Yuuto Noboru. Her childhood years also began at the laboratory unit of the Estraneo famiglia. Rosso was one of the children who were experimented and injected with several of mutant chemicals which caused her hair to turn into a pile of venomous red pythons whenever blood spills out from her body. After her tests were successfully accomplished, the Estraneos sold her to Yuuto Noboru, who made her his student. Noboru raised her and trained her every time he arrives home to Italy. He even let her join with him with a few of his assignments. Every time Noboru arrives from Japan, he tells the young Rosso stories and news about his daughter, Nagi. Soon after Noboru's last mission to work for Mafia, he entrusted her and left her to the caring hands of the Ninth Chavallone boss. Before leaving her, Rosso promised her mentor that she will travel to Japan and visit him and his family to meet his daughter as soon as she grows up. Years passed by, Rosso continued being with the Chavallone family and became a close friend to its up-coming leader, Dino Bronco. They've studied middle school, high school and college years together with several of his friends. Days after their graduation, Rosso was given an assignment to the Estraneo family where she met a young man who resembles her mentor. Hiroshi asked her to come back and join the Estraneos again but Rosso refused at first, until she was told about Noboru's death. Not knowing how to excuse herself, she ran away from the Chavallone family and went back to serve the Estraneo famiglia. When the Vendice gave their trust to Hiroshi, Rosso was the one responsible with the strong thunder-storm that hit the water prison, aiding Hiroshi's mission to kidnap Mukuro Rokudo. Days after the mission, both guardians were once more assigned to kidnap Chrome Dokuro and Hibari Kyouya. Rosso faces Vongola's cloud guardian during Chrome's return party and have of course victoriously dozed off both of the wanted victims. She then at long last met the daughter of her childhood mentor, allowing Chrome to use Rosso's room for a mean of time. As soon as dawn awakened after the meeting, the Vongola family gave an assault at Estraneo's laboratory base to rescue Chrome. Rosso faces Hibari for the second time together with her former comrade Dino Bronco.
Personality: Rosso used to be as shy yet sweet young girl just like Chrome; not until when she knew about Noboru's death, she became stricter with her life and even to herself that she became quite a hard-head-strong woman. She's calm most of the times though her temper only loses whenever Hiroshi teases her. Even though he's such a joker during his free time, Rosso still respects him as a higher-guardian and her mentor's son that she follows every order that he commands.
