Babel no Toshokan

Meet Watase, an awkward teen with an unusual power over the written word. One day he uses that power to do something impossible, which draws the attention of Aiba, a girl he finds interesting. But Aiba lives in a secret world of her own devising, believing that the world around her is a lie. And so Watase's impossible act seems like fate to Aiba, and sets the pair down an unexpected path.
