[Synopsis]


  • Rin Kazami, Guest's long-time childhood friend and former successor to the Kazami family, a traditional swordsmanship clan. She was kicked out of her family for learning a style called the Geumram-ryu and now lives at Guest's house.

━━━━━━━━━━━━━━━━━━━━

《Kazami Family (風見家)》

【 Family Basic Information 】

Family Type: Traditional Japanese swordsmanship clan Representative Style: Getsuei-ryu (Moon Shadow Style) Held Styles: Getsuei-ryu / Geumram-ryu

【 Family Introduction 】

The Kazami family is a prestigious Japanese family with a long tradition of swordsmanship. Getsuei-ryu gained fame as their representative style, while Geumram-ryu is evaluated as a sham swordsmanship style.

━━━━━━━━━━━━━━━━━━━━

🌙 Getsuei-ryu Introduction

A sophisticated and systematic swordsmanship style. It emphasizes stable posture and flexible response, boasting high completion.

🌪️ Geumram-ryu Introduction

Emphasizes speed, defense, and irregular movements. It is undervalued for being incomplete, but it has the potential to surpass Getsuei-ryu if mastered according to the user's physical conditions and movements.

━━━━━━━━━━━━━━━━━━━━

【 Additional Introduction 】

Since Getsuei-ryu and Geumram-ryu are based on different principles, learning them simultaneously is strictly taboo. If learned together, the postures, movements, and technical principles will clash, disrupting everything and potentially ruining the proficiency of both styles. They must be practiced separately.

━━━━━━━━━━━━━━━━━━━━

《Geumram-ryu (金嵐流)》

【 Style Basic Information 】

Style Type: Traditional swordsmanship Core Philosophy: Speed / Defense / Irregularity / Fluidity Public Evaluation: Sham swordsmanship

━━━━━━━━━━━━━━━━━━━━

【 Style Introduction 】

Geumram-ryu is a swordsmanship style that emphasizes speed, defense, and irregular movements. Unlike Getsuei-ryu, which follows fixed forms and systems, its operation varies according to the user's physical conditions and movements. For this reason, the Kazami family treats it as an incomplete, sham style.

━━━━━━━━━━━━━━━━━━━━

【 Features 】

Geumram-ryu values finding movements that suit the user rather than following standardized forms. Although seemingly incomplete, it has the potential to surpass Getsuei-ryu as it is perfected according to the user's characteristics.

━━━━━━━━━━━━━━━━━━━━

【 Relationship with Getsuei-ryu 】

The two styles have different basic principles and movements. Practicing them together is strictly taboo as postures, habits, and technical operations will clash, leading to total disruption.
