Kidō

is one of the four basic Shinigami combat forms, at least according to Captain Sōsuke Aizen.

Kidō is the technique that Shinigami use to focus their Spiritual Energy into magic spells of various powers. These spells serve a wide variety of uses such as healing, defense, or combat.

These spells are graded on a scale of 1 to 99, the latter being the most powerful and the most difficult to perform. In order to use Kidō one must say the incantation and state the name of the spell and it's number. For someone skilled enough in Kidō, the incantation is not necessary. There are three main types of Kidō: binding spells, destruction spells, and healing spells. Binding spells are a broad category referring to anything designed to halt or deter an enemy, destructive spells refer to anything designed to specifically harm an enemy, and healing spells, which do not require names, numbers, or incantations to cast, simply heal the Shinigami's comrades.

4. — An energy rope entangles a target's arms. Incantation: unknown/none.

Incantation: "Heart of the south, eye of the north, finger of the west, foot of the east, arrive with the wind and depart with the rain."(" 南の中心、北の目、西の指、東のフィートは風と、着き、rain."と出発する;)

Other
These spells are not explicitly stated to be in one category or the other.


 * — Momo Hinamori uses this spell while imprisoned to knock out a guard and destroy everything within a certain radius of herself. The anime suggests that it is a binding spell, but doesn't number it.


 * — Tōshirō Hitsugaya used this to seal Momo Hinamori's hospital room. It creates a glass-like barrier which is difficult to break from the outside, but quite simple to break from the inside.


 * — This technique nullifies an opponent's kidō by hitting them with a perfectly opposite surge of energy. Yoruichi uses this against Soifon's shunkō.


 * — As the name suggests, the Kidō Cannon is basically a high-intensity energy weapon powered by kidō in Bleach: Memories of Nobody. It consists of a crystalline focus point attached to the top of a massive pole, with several smaller crystal structures circling up towards the main one. It is powered by hundreds of shinigami working in concert, creating an energy blast capable of obliterating a small dimension. The blast forms into several animal shapes which roar just before contact. The power of the blast is such that, in addition to destroying its target, it also causes a small amount of damage to both the human world and Soul Society. Despite its power, it is not a reusable weapon, as it burns into a pile of scrap after being fired.
