Haruka

From a tender age, Haruka has been secretly groomed by the Tobun family to be a sharp blade. The sole family rule is to be loyal to the family. This sharp blade was extensively used by Sakai to eliminate threats, especially during the family's five years of turmoil. Most people see Haruka as a ruthless killer due to her cold expression and constant frowning. But the truth is, she's merely lacking in social skills as she's been obsessed with sword training for years. She has a hard time catching the underlying meaning in people's words, and frowning is actually a sign of her trying to understand it all. To Haruka, words are simply a tool to hide one's weakness. "Only weak people beat around the bush. My sword will decide whether I should agree with you."

Many people in Tobunkai would tremble at the mention of Haruka's name. Rumors about her are everywhere, with the most terrifying being a "kinslayer".

At first, Haruka tried to explain that she was only trying to protect her mother. But the adults gossiped in front of the silent child. "Look at her! If she could kill her own father at this age, what would she do when she grows up?" They believed that Haruka was disrespectful and not being understanding of her father who had been supporting the family. "What's wrong with a husband disciplining his disobedient wife?"

After that incident, Haruka became tight-lipped. The gossips intensified, to the point that people would say she would betray her family in the future. Amidst all these, Sakai offered her a way out. "So what if you're an evil woman? Come and be my blade."

Even though Haruka is called a killer, she never tries to explain herself. Her kindness is saved for her comrades in Tobunkai.

She would take note of each of her comrades' likes and dislikes, and listen closely to every word they say. Every time she comes back from a mission, she would bring back something her comrades wanted. Someone once asked her why she would do that even though there are people who may not appreciate it. Haruka smiled and replied, "I treasure each day when we are comrades, because we could be enemies one day. When that day comes, I don't want to regret not getting that candied apple for them."

Nobody knows what really happened on the day Shozan Sakuma was assassinated, but Gensai Kawakami, one of the four great samurai of the Bakumatsu period, sealed his sword afterwards and allowed himself to be captured. Some say he did it out of guilt, because he had to kill Shozan using underhanded means. Gensai knew very well how he was shocked by a frail scholar. His heart started wavering when he saw how a man could be so firm in his beliefs. He wondered if his own persistence was wrong. On the day of his execution, without finding the answer, he became a Lens and quietly waits for the day when he could see that new world.

Haruka has never tasted defeat. Once, she accepted a seemingly easy mission, which was to assassinate Takuya's tactician, an opponent far weaker than her.

Despite that, Takuya's tactician refused to give up. He grabbed his weapon and gave all he got. Even after his weapon broke, he continued to fight with his broken blade. Haruka was shocked by his determination. The heavily wounded Takuya saw an opening and dealt a crossed slash on her abdomen. Although Haruka completed her mission, her heart started to waver. When she picked up that broken blade, her heart and Gensai's connected somehow. "Perhaps we should take a look at the other side of the world." Since then, Haruka mostly uses the broken blade in battle. She no longer seeks to kill, but to defeat.
