"Rock, Scissors, Paper" known as the greatest mathematician in the Andromeda galaxy,
came down to Earth with a dream of conquering the universe!

Earth's friends were "losers" recognized by their "F" grade scores,
but with overnight study and the help of a neighboring village tutor,
they rose to a "B" grade level on their tests...

"Still... not enough."
"They are at a level of the top 1% in the country..."

With the help of Dr. Einstein, Earth's friends received gloves
that enhanced their learning ability through battles of rock-paper-scissors.

And so, their long and arduous mathematical war against the extraterrestrials began.
