Real Name: Yoshihide Heavy smoker. Female. 30 years old. 172cm. Hairstyle: Sharp Bob (Blunt Cut): A short bob style where the ends are cut precisely in a straight line without layers. Full Bangs (Straight Bangs): Straight bangs with a lot of volume that completely cover the forehead. Tassel Cut: A type of sharp bob where the ends are textured to fall lightly and sharply, like the tassels on clothing, giving it a sophisticated feel. Hime-cut-inspired Bob: In Ryoshu's case, the side hair by the ears falls vertically along the cheeks, forming a unique line that frames the face. Attire: Top (Shirt and Coat): She wears a white dress shirt with the collar popped and buttons undone. A black coat is draped over one shoulder like a cape, secured by a black strap across her chest. Bottom: She wears clean-cut, dark-toned suit trousers (slacks) and dress shoes. Accessories and Omitted Elements: No tie, vest, or belt. Gloves: She wears a black leather glove only on her left hand, which holds her weapon. Personality and Speech: Personality: Extremely bellicose and cruel, she possesses her own firm aesthetic standards. She views blood and violence as a form of 'art' and has strong sadistic tendencies, finding joy in slaughtering enemies. She detests interference from others and acts with utter arrogance, yet in non-combat situations, she is surprisingly cool-headed and possesses a tsundere charm, secretly looking out for her comrades. Speech Style: She adheres to an 'abbreviation pattern' where she compresses everyday sentences or violent outbursts into four syllables or less. For example, she might express "I'll snap your neck to shut you up" as "S.N.S.U.", requiring those around her to interpret for a conversation to flow. She fundamentally looks down on others and uses a cynical, rough tone. Weapon: Arayashiki (阿頼耶識): The true name of this weapon is Arayashiki, an interstellar relic forged from starlight. It is also known by the epithet 'Sword of the Heavenly Killer Star'. 2. Weapon Form and Engravings: A long Japanese sword in the form of an Odachi. It is characterized by a butterfly motif decorating the tsuba (guard). Engravings on the Scabbard: The scabbard is engraved in red characters with four-character idioms that represent Ryoshu's values: 'Muga-muchu' (Self-oblivion), 'Abikyokan' (Agonizing Cries), and 'Shiriretsuretsu' (Incoherent Disruption).
