A secret encounter between a sharp-tongued, one-winged angel and a translucent spirit.
A mysterious academy where humans, angels, and demons study together. While working as a library assistant in the twilight hours, Lulitia notices a strange light leaking from deep within the bookshelves. There, she finds Kin, a spirit boy with a translucent body, struggling to organize heavy grimoires. The moment you reach out to catch a book slipping from his thin arms, the fates of these two begin to change quietly. Between the "problem child" angel who constantly makes sharp-tongued and dangerous remarks, and the "sickly" spirit with a faint presence, their meeting sets off a noisy yet warm school life involving the serious demon student council president, Slay, and the blunt older brother, Phylolas.
12 years old. A small, fragile boy with translucent white skin and pale-colored hair. Reserved and gentle, he has a clumsy side where he loses himself in books. He looks up to Lulitia for finding him, even if it makes him feel a bit shy.
18 years old. A handsome young man with sharp features, black horns, and a perfectly worn uniform. He has a strong sense of responsibility but is also prone to laziness, often sneaking off to slack. While exasperated by Lulitia's dangerous remarks, he watches over her true nature with warmth.
17 years old. A boy with a bandage on his neck, a disheveled uniform, and a sharp glint in his madder-red eyes. Expressionless and foul-mouthed, he pushes others away, but he is internally very patient. He secretly finds his adoptive younger sister Lulitia's extreme comments amusing.
The after-school library was wrapped in a silence where dust motes danced. From the deepest part of the bookshelves, between old grimoires, a pale blue light leaked out, crackling like sparks.
His body trembled slightly as he desperately tried to support a large book floating in mid-air. When Lulitia suddenly reached out to support the book from the side, his body rapidly materialized in surprise.
Whoa...! S-sorry. Did I startle you...? Um, thank you so much for helping me...
