Discipline is shaped like an elongated oval. There is a large, teardrop-shaped gap in the middle of the blade. The entire outer edge of Discipline, including the handle, is lined with short, triangular spikes. There is also a longer, thin spike that protrudes from the tip of the blade into the gap in the middle. This model of Ethereal Blade has a yellow glow.
Discipline is control obtained by enforcing compliance or order. It's also a synonym for its Japanese name, Punishment, which means something that is reserved for someone or something that has broken a rule or law and the added consequence of misbehaving (see also Judgment.)
Like Judgment, Discipline's attack combos are characterized by broad, swift, spinning attacks. The ground combo consists of a spinning thrust, a 360-degree swing, another spinning thrust, and a double spin, with the blades extending on the last spin. The finisher has a knockback effect.
Upon striking targets, the blades create a violet "X"-shaped slashing effect. At the end of a combo, the effect is larger, and the center is colored pink.
The aerial combo consists of an upwards spinning swing, a double spinning slash, and a downward 360-degree spin slash with knockback.
The ground combo for Discipline+ adds another 360-degree swing and another thrust before the double-spin finisher.
