Bleach: Black and White Kido

"Kidō (鬼道, "demon way", or "spirit way" sometimes translated as Demon Arts; Viz "Soul Reaper's powers"; "Spells") is the technique that Shinigami use to focus their Spiritual Energy into a wide variety of magic spells that can serve many purposes, such as healing, defense, or combat. According to Sōsuke Aizen, it is one of the four basic Shinigami combat forms.[1]

The Kidō Corps is a branch of Soul Society's military which excels in the mastery of Kidō."
