Cardinal

A common summoning sub-weapon used by Maria that involves twin cardinals being released into the air. One moves upwards diagonally in one direction, while the other goes in the other direction. They then return to her.

Appearance in Rondo of Blood
In the original Rondo of Blood, one bird is released at about 45 degrees straight upwards in one direction, then the other is released 45 degrees in the other direction. They then return following the same path unless Maria has moved. This is the smallest amount of hearts used by Maria for a subweapon and deals out a small amount of damage as well. Its item crash involves a giant red bird grabbing Maria by the shoulders and then it proceeds to call forth a field of flaming piercing feathers from the sky in a downwards diagonal direction.
