What is shinji's bankai?

Answer 1

Sakanade (逆撫, Counter Stroke): In its sealed form, it resembles a normal katana. The hilt and sheath are red and its guard is shaped like an hour-glass. Sakanade's Shikai

• Shikai: The release command is "Collapse" (倒れろ, taorero).[68]In its Shikai its hilt becomes a large ring which Shinji places his hand in the middle of allowing him to freely control its movement without physically holding onto it if he so chooses. The ring is attached to a normal sword hilt with a normal rectangular hand guard. The first few inches of the blade are covered by a extension of the hand guard. Sakanade's blade is straight and slim with the tip ending in a slanted razor-like edge instead of being tapered to a point. There are five holes along the swords length.[69]

Sakanade's Special ability

Shikai Special Ability: Sakanade's Shikai ability creates an inverted world. The power is an optical illusion which is caused by the scent the sword gives off upon its release. It inverts an opponent's sense of direction. Shinji describes the release technique as something like a trump card. Up and down, left and right as well as forward and backward are opposite. It is not just the sense of direction that is changed; the opponent's eyesight and where they get cut is reversed as well. Shinji claims that countering the damage from the inverted directions simply by processing it all within the mind is not possible. No matter how powerful the opponent even if one is accustomed to fighting in that particular way, their body will not adapt and will continue to fight by reflex, which causes it to continuously succumb to the power's effect.[70] The effect of the inverted world can be targeted at a specific opponent, making it ideal in use of group fighting.[71]
