Meili Portroute/Relationships

Elsa Granhiert
On Mama's orders, Elsa met Meili Portroute in a forest. At that time, Meili did not know how to talk or act like a human being. Because of the latter, she started to admire Elsa and began acting like her. Elsa quickly became Meili's purpose to live and could not imagine what life would be without her, as she taught Meili how to talk and live her life.

After Elsa's death, she was extremely troubled by this. In fact, she promised herself to she would kill the one that killed Elsa Granhiert.

Mother
Having ordered Elsa to retrieve Meili, she was indirectly responsible for Meili's "saving". Having showed Meili her place, the aforementioned Beast Master had a great deal of respect and awe towards her. If Meili ever failed Mother, she'd be turned into a bunch of frogs, greatly traumatizing the young assassin. After Elsa's death and Meili's defeat, she is currently hiding from the organization as appearing before Mother once again would lead to her certain demise.

Shaula
During her stay at the Pleiades Watchtower, Meili becomes attached to Shaula, who she refers to as "naked onee-san", and typically spends her time hanging on to her shoulder. After Shaula was reduced to a small scorpion Demon Beast with no sign of her original personality, Meili still takes care of her, carrying her around on her head.
