Description: Chidori • Eiso is a Lightning-based technique developed by Uchiha Sasuke. Sasuke is able to shape the Lightning Element to form an extending spear of lightning. Though unstated, this spear takes on Chidori's characterists, including it's ability to cut through anything which stands in its path, allowing the sword to strike its target with ease. This attack may also be similar to Chidori • Nagashi, causing the target to go numb from the electrical charge.
Users: Uchiha Sasuke.
