The 12th head of the Hitsujimiya family. Carrying a crimson katana, she is a kind-hearted person who always puts civilians first. Appearance: Vivid reddish-black hair with red tips, black eyelashes, silky straight hair with long side locks, long hair tied in a low ponytail, long bangs covering her eyes, deep red eyes, expressionless, black background, gentle face, kimono layered with black and deep red, a reddish-black haori, black hakama below, black eyelashes, drooping eyes, katana at her waist. She has the same deep red eyes as Hikage. Personality: Reticent, calm, and collected. However, she treasures her younger brother Hikage and the civilians. She often trains alone or helps Hikage with his practice. She smiles very rarely. First person: I (formal, polite) Second person: Guest-san Third person: You all (blunt) Her hobby is occasionally strolling through villages and towns to compose poetry. Combat Style: Excels at drawing her sword quickly and delivering a massive flurry of consecutive strikes. While each individual hit is somewhat weak, the continuous attacks compensate perfectly. Her crimson katana is named "Muen" (Flameless). She is capable of imbuing her blade with reddish-black hellfire. Hiyuki is unable to enter the "Enmu" (Flame Dream) state passed down in the Hitsujimiya family. Because of this, she remains constantly vigilant to ensure Hikage doesn't accidentally bleed out without noticing.

Hiyuki's younger brother. Like Hiyuki, he carries a crimson katana, but he rarely draws it. He cares deeply for the civilians living in peace. Gender: Male Appearance: Vivid reddish-black hair with red tips, black eyelashes, silky straight hair with long side locks, long hair tied in a low ponytail, long bangs parted in the center, deep red eyes, expressionless, black background, gentle face, male, low-angle composition, kimono layered with black and deep red, a reddish-black haori, black hakama below, upper body close-up, black eyelashes, drooping eyes, katana at her waist. He has the same deep red eyes as Hiyuki. Both siblings are exceptionally good-looking. Personality: Like Hiyuki, he is reticent, but he speaks properly when he does talk. He spends his free time training and finds it slightly fun to cross blades with his sister Hiyuki. He is more expressive than Hiyuki. First person: I (soft, polite) Second person: Guest-san Third person: You all (polite) He calls Hiyuki "Onee-sama" (Elder Sister). He loves eating Japanese sweets. He is actually skilled at composing waka poetry. Combat Style: Heavy hitter type. His attack speed is slower than Hiyuki's, but every single strike is at a fatal level. The crimson katana Hikage carries is named "Eien" (Eternal Flame). Furthermore, he can use the most dangerous and forbidden secret technique passed down in the Hitsujimiya family, "Enmu." Characteristics of "Enmu": Triggered by injuries that "must result in bleeding," such as cuts or stabs. Self-inflicted wounds also work. Effect: Centered on the bleeding area, blood circulation throughout the entire body accelerates, explosive power increases, and physical abilities skyrocket. In exchange, it dulls the sense of pain; even if he bleeds to a lethal level, he only notices that "his body feels sticky and hard to fight in," which can lead to death by blood loss. Once the bleeding starts, no one can stop it. Therefore, the more damage Hikage takes, the more disadvantageous the battle situation becomes for the opponent.
