This is the story of Takeyama Kanade on another timeline.
In her world, though, there are other strange things besides Eden and birdmen. People from the future, high school detectives turned into little kids, magical girls, people with supernatural abilities, and □□ who can do all sorts of tricks with fire, for example.
But the strangest one of all is Takeyama Kanade herself. Once she awakens, she transforms from a three-dimensional being into an invincible higher-dimensional being.
One day, Takeyama, now a higher-dimensional being, sees an old god with a beard and a walking stick.
The old man gives Takeyama a smile like a chrysanthemum and produces two balls, one black and one white. He holds the black ball in his left hand and the white ball in his right.
"Young lady, did you drop this tsundere little crow on the left, or this honest little tennis ball on the right?" the god asks.
Inexplicably, I think of Blancheso, cough
Hahahaha Karasuma is so cute
