Our protagonist, Inoue Konoha is still being led around by his senpai,
the Literature Club's President, self-acclaimed "Literature Girl" who
loves stories so much that she can eat them, Amano Touko.
One
day, someone put in the Literature Club's "Love Consultation Post Box" a
bunch of paper scraps that have the words like "Hate", "Ghost is" and a
bunch of puzzling numbers on them. Calling the act as "picking a fight
with the Literature Club", Touko once again got Konoha involved in her
investigation; but when they found the culprit, this girl turned toward
them, smile, then said "I'm already dead."
This is the second arc of the popular bitter & sweet school mystery series.
