    • A short time later, after correctly deducing that Smog was the assassin who poisoned the entire class with the virus, Fuwa mimics Yako Katsuragi's Catchphrase by pointing at the culprit and dramatically declaring, "The culprit was you!" She then makes this not-so-subtle statement:
      Fuwa: Eh, Jump's mysteries? I dunno, but I hear their paperback edition is out, so maybe I should buy it.
