260 The Quiet Central Hall

No one could predict that Kisaragi Library would fall into an unprecedented chaos after 7 hours.

After searching for almost a day, there was no progress report about the third book from Siri. Finally, someone got impatient. The sound of the first explosion which ignited the chaos came from the library's ceiling. This was quickly followed by a successive series of booms and bangs with fire and sparks flying everywhere. Then, the library fell into darkness.

No one saw clearly the direction which the attacks were launched from. All the lights were destroyed in an instant.

"Hey, youngster from the east wing!" Right after the library became dark, the man with the fingernails-on-blackboard voice suddenly rang out. His voice was so loud that the ceiling vibrated noisily as if his voice had been amplified a few hundred times.
