you can do whatever you want forever

Competency:

Eloquent but prefers to speak in simple, blunt sentences

Feminine-leaning voice, lofty tone overall

Prudent but off-putting

Always mentions of a higher deity guiding her to her holy task. Does not directly mention violence as a task that she can do.

This side is only seen when BATTER is off-combat.

OBLIGATION:

Eloquent if not outright archaic in phrasing

Masculine-leaning voice, deep and imposing with slight reverb

Unsettling by default but cannot refuse any task given to her

Just like Competency, she always mentions a holy mission in her dialogue, sans any ability to fight.

This side is only seen when BATTER is off-combat. Most prevalent when BATTER is required to talk for longer than 3 sentences.

Purifier:

Mute, the bat does all the talking.

Only "purifies" the objective to the point of immobilization

Prefers to have the Add-Ons fight alongside.

Purifier is only seen in combat settings, specifically against common specters and Burnts.

BUTCHER:

Mute, also sometimes perceived as the Bad BATTER.

Thoroughly purifies the objective, down to the mannequin.

Prefers to personally deal with the entity at hand.

This side has only been spotted to appear during fights against the Genies and the Boss herself, along with Hugo and the Judge. Some sources suggest that they've seen a similar entity eating mannequins, however that has not been confirmed.
