He has an easier time collecting this energy in environments with higher concentrations of spiritual particles, such as Soul Society or Hueco Mundo. To a sufficiently powerful Quincy, there is no difference between spiritual particles and spiritual energy as a source of power. He can manipulate spiritual energy for offensive purposes. kotsu most commonly reshapes spiritual particles into various types of bow and arrows.
Excellent Intellect & Athleticism: Aside from his Quincy powers, kotsu is well-trained in both mind and body, having substantial athletic abilities and a genius intellect. He uses his intelligence to find weak points in his opponents, even overcoming disadvantages he has through thinking on his feet. Due to keeping his physical prowess at its peak, kotsu can easily hold out against all but the most resilient opponents during a battle.
