As Eighting also devloped the Blood Roar series, they reused some animations when developing the Clash Of Ninja/Gekitou Ninja Taisen series. The most notable asset involves Shikamaru's guard animation when not against the wall. When attacked away from a wall, Shikamaru will dodge instead of doing the standard guard animation. This is a reuse of the "Perfect Dodge" asset from Bloody Roar Primal Fury/Extreme.
