Sento Ryu

The study of zero range combat principles


The Samurai were the strongest military force to have stride across Yatan. When Samurai were first trained, they quickly filled Yatan’s ranks. Before Samurai, soldier’s were mostly just typical medieval soldiers. However, there were many periods where specialized soldiers were favoured, but nothing like the all-around usefulness of Samurai. In modern Yatan, Samurai have been made null, but nations still trained and maintained large Samurai armies. The Sento concepts and principles date back as far as the 12th century until the late 1870’s.
