Sno's voice was so abrupt that Klein reacted as if his parents had suddenly walked into the room while he was reading an illicit novel as a student, instinctively trying to hide the book behind his back.
However, since the book had no physical substance to collide with, Klein's instinctive movement passed straight through it, grasping at empty air.
Still, it was only a reflexive reaction. Once Klein's thoughts cleared slightly, he gave up on the idea and awkwardly looked toward the source of the voice. Then he saw Mr. Devil crawling out of a drawer that had suddenly popped open from the desk.
Did you come from Doraemon or something? Klein inwardly mocked, his gaze toward Sno becoming somewhat strange. Sno, who had just jumped out of the drawer, brushed at the hem of his clothes and, seeming to see through Klein's thoughts, said:
"This is a transport window designed by my ancestor. Altering it would mean renovating the entire transport route, and both the construction time and cost would be considerable, so we can only make do with it."
"..." Klein stared at the drawer and suddenly felt that this senior had quite a sense of nostalgia.
But when Sno gestured for him to jump into the drawer as well, Klein immediately pointed at the illusory books on the bookshelf and asked tentatively:
"These books..."
"My ancestor made these using some kind of secret technique. You need the abilities of a Marionettist to read them, though in fact, possessing a Marionettist's Beyonder Characteristic is enough. However, these books can't be taken out of the Ancient Tower's illusory space, and their contents aren't particularly important, so they were left here. Of course, I copied all their contents. If you want to read them, I can lend them to you."
