──You go to see the cherry blossoms?
──To go count the petals of the Yaezakura.

In the middle of the opening ceremony.
A boy encounters another mysterious boy in the shade of the cherry trees above.

──She's only visible to me, right?
──The girl hanging there, I mean.

What he had seen, was it a dream or an illusion?
Or perhaps──it was reality?

Led by an eccentric woman called Kureha, both youths are confronted with real youkai – living, breathing dog spirits that appeared in front of their very eyes.

"You have incurred the wrath of the 'Inugamisuji'."
