"Muria, Miss Mikaela invites you to come to Cloud City and asks you to bring your weapon."
In the ancient stone palace, there lies a gigantic stone bed crafted from mountain rocks, upon which, a pile of sealed books that have been treated with protective magic such as "Dust-free" and "Immortal" accumulate like a mountain.
Above the books, a black-haired and golden-pupilled boy lay lazily on a pile of books, with a book of spells nearly as large as half a person floating in front of him, turning pages occasionally.
Right next to him are three red-haired and red-eyed lolis who look slightly older than Muria, each of them reading a book. However, in contrast to Muria who is reading with great interest, these three girls all look rather sleepy.
On the side of the boy, there is another white-haired and white-eyed loli who is exuding an icy cold aura, captivated in reading a book, seemingly not attracted by any external distractions.
