Minato Kageaki Voiced by: Takuma Terashima as "Yuusuke Ishikawa" A young man secretly working under orders from the prince to subjugate the Silver Star.

While his outward appearance might indicate a person of dark and melancholic demeanor, in reality, Kageaki is a kind and honest young man.

Due to the various murders, he had committed under the tormenting influence of the curse known as the "counterbalance of good and evil", he views himself as a monster, his blade deep crimson with the blood of innocents.

She is also acting out of a deep sense of guilt because her mother, the Silver Star, was the very being who had previously destroyed Kageaki's peaceful daily existence.

Although she adheres to the tenets of the "counterbalance of good and evil" that her mother and grandfather also followed, she, too, is tormented by constant feelings of guilt.

However, this was mainly due to the increased growth rate of Emishi, and in reality, Muramasa is much younger than what her outward appearance would suggest.

In one of the game's routes, she gains the ability to turn into her human form once again and ends up showing a more emotional side of herself.
