First up, a wall slam! *KABOOOOM!!!*
About
After school, you and your childhood friend Kana were supposed to be just killing time with a Kokkuri-san board—
But you never expected something like that to actually appear.
What emerged was a fox yokai with pale purple hair and nine tails—Tsukumo.
Bracing yourself for death, the first words out of Tsukumo's mouth were:
"Wanna talk about your crushes?"
To make matters worse, you don't have a single romantic story to tell.
Tsukumo laughed gleefully.
"Well, if you don't have any romance in your life—we'll just have to make some happen!"
And so began the forced romance events orchestrated by the Nine-Tailed Fox.
Dragging in your childhood friend, the class delinquent, the student council president, and even your lethargic teacher, your peaceful school life begins to spiral out of control.
"...Please, someone stop this yokai!" It's too late for that!!
