After the battle with Lord Caspar and the whole conclusive arrangement with Lucas, everyone has gone back to the library to settle things.
Since bringing Cosette back to the dormitory will stir people's curiosity, especially the headmistress, they decided to let her rest inside the librarian's office for now. She was knocked unconscious a moment after her uproarious outburst, and as of this hour, she remained sleeping.
Fortunately, they have a summoned creature that possesses healing magic.
"I can't believe we'd be switching positions like this. Last time, your comrade was the one who needed healing, but now... Who would've known that we'd be indebted to you this way for the second time I'd be seeing this... bird. And you named it Calliope, huh?" Wes asked, awe and wonder faintly written over his face as he watched how the mythical bird serenade into the night.
