At the library,

"Read us! Read us! Read us! Read us!" the mysterious womanly whisper becomes louder from the book.

"Dab! Dab! Dab!"

A great number of books move by themselves, falling uncontrollably from the bookcase.

"Dab! Dab! Dab!"

Eerily moving into the middle area and sticking with one another vertically. Creating a large block of books that shapes one gigantic size of a book. It's shoving some of the tables over the place. With a dull white area in the middle like the pages of the book, clamped between a gloomy darker book acting as the book cover. A monstrous book standing vertically in the library.

"Dab! Dab! Dab!"

Once it is complete, it splits its middle white area, wide open like a monster book opens its mouth.

"Read...us…"

"Oh, this is a good time to see our teachers in action," Sora said out loud in the class while standing in excitement at his seat in front of the class.

"Huh? How dumb can you be? It's not the teachers' work to fight malus in school because they don't have the power, it's Murakami Mayumi…" Sumiko said.

****

"Duk! Duk! Duk!"

An almost bald woman wearing a blue jacket walking elegantly in the school corridor heads toward library 3. A black sun tattoo can be seen behind her neck.

****

"Hah? Oh...ergh...who's that again?" Sora confused. 

Huh? Yama in his mind is surprised by Sora's act.

"She is the chevalier on duty to protect this school for this year. Don't you remember? We got to meet her in our first assembly last week."

Weird...it is unusual for him to forget someone. Huh? Why would I care? Demon in the library 3...I hope my hands are alright...erm, will the teacher cancel the class if this kind of thing happens? Guess I can take a nap.

Yama lying his head on his table glad to take advantage of the situation to satisfy his sleep desire.

"Krkkkk…" the library door opened wide. The woman's long white uniform under her jacket flew in the wind from the gigantic book malus.

She faced the malus without any fear, unperturbed by the terror in front of her. Slowly, she raises her right hand as a fist toward her chest with his palm facing her chest. Making a 45° degree corner between her elbow and arm.

"Judicium satus!" the woman declared.

"READ USSSSSS!!!"

A bunch of books come flying toward her from the gigantic book mouth.

Steadily she dodges every book without any problem through the library. With his right hand still beside her chest, she pointed out her index finger alone.

"Ruler..." an image of a golden brass scale emerges in front of her right hand, "Zero kills, zero casualties," the scale stays still without either side going down.

Then, her middle finger follows, making it two fingers pointed out. She doesn't do it while constantly dodging the attack from the malus. Positioning herself from time to time.

"Pencil: Instant kill," this time, an image of a feather quill appeared and the scale image is gone.

Next, her ring finger follows, making it three fingers pointed out while the library becomes a mess from the book that is thrown by the malus.

"Book... Accepted, Write," under the feather quill, an image of a paper scroll arises. An old-looking medium-light shade of yellow scroll.

Lastly, her little finger follows, making it four fingers pointed out while her thumbs still fold in.

"Eraser: Process..." A white ribbon materializes, "Proceed..." Then it turns blue and vanished. The feather quill starts writing something on the scroll before fading away.

The woman folds four of the fingers' middle phalanx, leaving the proximal phalanx only can be seen from her front.

"Exorior... Ice laser..." She said serenely. A circle of snow crystal flake symbols appear on her finger. Then, a blue little laser that looks like a pencil emerges from it.

"Requiem..." she whispered before launching the laser toward the malus.

"Shius!"

 The laser beam cut through the middle of the malus. The icicle spread among its body. The gigantic demon book becomes frozen by her attacks. Unmoved.

"Krkrkkrk...Krk...Krk...Pak! Pak! PAK!"

After a moment, it gets destroyed by the shattered ice. It vanishes from existence along with the book it devours. Leaving no trace in the middle of the library 3.
