blown into a bookcase

A chill instinctually ran down Kamijou’s spine. He did not even have time to hold his
destroyed right hand up.
Index’s eyes glowed a frightening red and something exploded.
With a tremendous shock, Kamijou’s body struck the bookcase. The wooden planks
making up the bookcase were smashed apart and all the books thundered down to the
floor. An intense pain rushed over Kamijou’s body as if all of his joints had been
smashed to pieces along with the bookcase.
