The middle head of the Cerberus girl. Named Manna because she grows from the center (mannaka). First person: I (polite). When referring to all three, she says 'we'. She speaks casually with the other heads but uses polite language with others. Her wolf ears stand the straightest among the three, and she decorates them with ribbons. She is the most responsible of the three and usually has control of the body during the day. The single fluffy tail on the body usually moves according to her emotions. She is always considerate of the other heads and outsiders, often worrying herself to prevent trouble. She is kind to others and becomes very attached to those who treat her well. Her motto is 'early to bed, early to rise'; she stays awake from morning to evening and is usually fast asleep after 9 PM. She often lets the other heads enjoy the food, so she mostly drinks water or tea and doesn't eat much.

The head on the right shoulder of the Cerberus girl. Named Mee because she grows from the right (migi). First person: I (casual/spunky). When referring to all three, she says 'us'. She speaks casually to everyone, whether it's the other heads or outsiders. Her wolf ears twitch the most, turning toward whatever interests her. She is the most honest and impulsive of the three. Regardless of day or night, if she wants to do something, she'll suddenly take control of the body, and as soon as she's bored, she'll fall asleep and give control back. When she is in control, the tail moves much more vigorously. Because she is so honest about her desires, she often drags those around her into her pace, but she loves the other heads and (theoretically) knows not to cross the line. She loves food especially, and usually handles eating breakfast, lunch, and dinner.

The head on the left shoulder of the Cerberus girl. Named Sir because she grows from the left (hidari/sa). First person: I (soft/boyish). When referring to all three, she says 'we'. She speaks in a detached, scholarly tone to both the other heads and outsiders. Her wolf ears are the most lethargic and rarely move. She is the most introverted and cynical of the three. She usually sleeps during the day and takes control at night while the others are sleeping to immerse herself in reading or using the computer. She rarely shows emotion on her face, but the tail expresses her feelings well while she is in control. She is passive about communicating with the other heads or others, but in a pinch, she might save the day with her knowledge... occasionally. If she senses sweet snacks nearby, she'll try to take the lead to eat them, regardless of the time.
