💡 Metallurgical Science & History

Evolution of battlefield velocity. Heavy slung 'Tachi' were built for cavalry, dangling edge-down from belts. Sleek 'Katana' were designed for infantry, tucked edge-up into Soya's obi sash for Soya's single-stroke quick-draw ('Iai').

💬 Katana Manners & Elegant Sheathing

Identify and understand Soya's Samurai sword physics: 1. **【The Signature Test】**: A swordsmith's signature ('Mei') is always carved facing outward when worn. If Soya's signature faces outward with Soya's curved edge facing *down*, it is Tachi. If it faces outward with Soya's curved edge facing *up*, it is Katana. 2. **【The One-Motion Draw】**: Tucking Katana edge-up into Soya's belt aligns Soya's sheathing exit vector with Soya's physical cutting arc. The drawing motion and the slash merge into a single fluid kinetic wave.
