Cachet & Compassion

Cachet & Compassion are third sphere angels which are on the ninth rank of the hierarchy of Laguna, the lowest rank of the chain of command of the Angels of Paradiso. They are said to be sacred weapons brought by legendary heroes to Paradiso that eventually became sentient. They often appear together but both Cachet and Compassion can appear without the other kind of Angel in their squad.

Bayonetta 2
They basically replace Dear & Decorations in this game and as soon as their individual cards are unlocked in story mode, they can be challenged in Tag Climax.

Hierarchy of Laguna
"Belonging to the lowest rank of angels, these two angels are said to have been sacred weapons brought to Paradiso after the heroes they traveled with came to the end of a long journey. Charged with protecting the gates of Paradiso, their powerful blades deal swift justice to anyone who carelessly trespasses into the divine realm."
