Erica was always a calm child. Being the eldest sister, she was always responsible for her 2 twin siblins while her parents were away. In keeping with tradition, her parents have sent her to the National Academy at age 10.

In the academy, she was very popular for her kindness and altruism, dealing well with people and mediating the fights that occasionally happened. Even though consistently highly rated in all academy subjects, she was considered a prodigy in handling Astra and controlling the bow and arrow. When she was holding it, something changed. A small smile crept onto her face as all her calm became focus, ensuring the most impressive hits and earning praise from her instructors.

However, it was during the Dawn of Winter that Erica gained her fame. Using complex enchantments to protect and heal her allies, creating arrows of pure Astra and firing them with incredible precision, she earned the title of Absolute Focus at the end of the event. Erica received the official invitation from all the matriarchs, but decided for the Gebo family, the same family that her parents are part of.

Following the new ideals received, Erica learned the value of balance. Be generous, but relentless in the face of the enemy. As a reward for her achievements and skills, at age 16 she received her Techno Bow: an enchanted technological bow, capable of receiving Astra charges and enhancing the skills of its user. She currently leads part of the Winter Sun Defense Forces.

Born into a family of humble origins, who owned a kiosk on the coast of Utsuichi, Hibiki helped her parents from a very young age. She learned to cook with her father, but the heat from the stove held another taste: alchemy. All thanks to a book that was forgotten there. While the owner was not found, Hibiki marveled at the new world that was in her palms. Even using the improvisation and the little resource he had, Hibiki managed to take her first steps alone within that mysterious science.

Days later, in search of the lost book, the alchemist heard about the girl's feats. Impressed, she promised to help her with the studies, bringing knowledge and resources whenever she passed through the region. But it would be up to Hibiki to work hard and learn.

As the years passed, her curiosity and effort resulted in a remarkable evolution. Not just in common alchemy, but with innovative manipulations and surprising effects. As a form of recognition, her teacher started to recommend some jobs. Due to the high quality of its products, Hibiki started to receive more and more demand. So she decided to set up a small shop, alongside her parents.

In a short time, Beco da Gata gained fame throughout Boralaa, both for its items and the peculiarities of its owner. Because she can't handle her addiction, spending nights reading and practicing became a habit. So it's common to find Hibiki taking naps in random corners of the store. And besides using only square vials for her potions, it's normal to see her head over heels in the most unusual places, thinking about solutions to her problems.

Kirishima was born into the Miyazaki tribe, responsible for the southeastern region of Utsuichi. Due to a mysterious incident that resulted in the loss of his parents, he was raised from an early age by the Kuwahara Clan, one of the most radical in the region. Shaped by the ideas of violence, chaos and freedom, Kirishima has become the perfect tool for the perfect plan: to end the Utsuichi Federation and all humans who live in it.

Following the orders of his leaders, his path was marked by assaults and executions. Even though he was young, traces of destruction and blood were left wherever he went. And he did everything with great pleasure, truly believing in the ideals he was taught.

On one mission, a group was tasked with breaking into an institution and destroying everything inside. Kirishima was given the job of burning down the place, and so he did. With his task completed, he went to meet the other members. As he approached, the heat from the flames mingled with crying and the smell of blood. Walking along, he found several bodies of human and semi-human children, brutally murdered. Confused, he ran for answers.

When he found them, they were entertained by a group of young people who were in agony, asking for help. After stopping them, he questioned what was going on and where they were. "Of course it's a school. Where else could we find so many little shits with human blood at once?" replied one of them. "We have to nip the evil in the bud" said another. Kirishima didn't understand why, but witnessing such a situation, both the state of those children in suffering and fear, screaming for their lives, as well as the pleasure of his colleagues, made him burn with hatred! How someone like him could feel that way, being the executioner of so many innocents. Why would seeing those kids in such a state have shaken him? Questions he didn't have time to answer.

Releasing all his rage, like a bear protecting its cubs, he fought off the attackers. No matter what attacks or wounds he took, he took down one after another. Before the building collapsed, he saved everyone he could. With the arrival of the Steel Claws, the clan responsible for dealing with the actions of the Kuwahara, the situation was brought under control. Everyone was in disbelief at what had happened, as the infamous Kirishima had saved 52 children alone. And in exchange, 50% of the body was charred. Taken prisoner by the Steel Claws, he survived thanks to the treatment received from the clan's healers. However, the aftereffects remained. Even standing up alone became a difficult task.

During the years he was in custody, he was constantly visited by the young people he saved, with gifts or gratefulness. Iconically, in all of them there was some mention of the Steel Claws motto: "Honoring the past, protecting the future". Even not knowing how to handle the situation, Kirishima started to feel strangely comfortable with the occasions. As time passed, he understood better the feeling of that fateful day. Everything he had learned as a absolute reality was nothing but a point of view corrupted by hate.

Around the age of 27, almost a decade after the event, Kirishima made a decision. To atone for his sins, he would do whatever he could to help the Steel Claws. He would continue to protect people in the same way he did that day. After a public hearing with a large part of the clan present, his request was accepted. Not only did it become an official member, but he was included in the REZ program: a partnership with the Republic of Tecnos for physical rehabilitation through technology and magic.

That was the first step in Kirishima's big turnaround. Who knew that 15 years later, he would become the successor and Boss of the Steel Claws.
