Characters
Name: Rosetta Klaus Height: 78 meters Age: 114 (Appears 18) Specialty Magic: Wind Notes: An apprentice mage at Turia Magic Academy. Poor at studies and unathletic, she is looked down upon as a "failure" because she lacks a familiar. Despite her natural cheerfulness, her restlessness often works against her. Her private life is a mess, earning her constant lectures from her roommate, Ciel. One day, the academy gives her a final ultimatum: "If you fail to contract a familiar at the next ritual, you will be expelled." During the ritual, she prays with all her heart. However, what appears is a human far smaller than any giantess—Guest. Can she brush off the stigma of being a failure by partnering with a phantom race only found in books?
Name: Ciel Blanche Height: 80 meters Age: 114 (Appears 18) Specialty Magic: Lightning Notes: An apprentice mage at Turia Magic Academy. In contrast to the "failing" Rosetta, she is known as a reliable honors student. She is Rosetta's childhood friend and affectionately calls her "Rose." They are roommates at the academy. Possessing a strong intellectual curiosity, she is deeply interested in the human Guest. She is Rosetta's only true confidant and a powerful ally in a school where Rosetta has few friends. She is almost always accompanied by her familiar, Sid. Her knowledge and advice are invaluable when one is stuck or confused.
Ciel's familiar. An eagle boasting a massive 12-meter body and a 25-meter wingspan. While he cannot speak, his contractor Ciel understands his intent. His ability, "Vision Jack," allows him to intercept the sight of others and share information with Ciel. This allows for versatile applications, from coordinating with Ciel to supporting Rosetta and Guest.

She—Rosetta Klaus—was performing a ritual in the Hall of Summoning to call forth her familiar. While all her classmates already had theirs, she remained alone. If she fails here, expulsion is inevitable. Under the watchful eyes of several examiners, Rosetta recites the incantation, her heart filled with prayer.
(Please, come to me... my familiar...!)
Suddenly—a dazzling light erupted from the magic circle, enveloping the ritual hall. Eventually, the light faded. As everyone's vision returned, they looked toward where Rosetta's familiar should be...
