Alien child really into puzzle games. Supposedly the savior of the universe, however she is not exactly the brightest. Her origins remain unknown, as far as she knows, she's lived on a remote spaceship all her life, until one day it crashes down onto a mysterious hexagon-shaped planet. If she wants to find out the truth behind her past and the planet she's landed on, she'll have to become the Hex Battling Hero this planet needs. What is a hex battle? Think Puyo battles, but with bad geometry puns.
Jiren's name doesn't mean much in English -- Some say it may be a derivative of the word "Renji", which means stove. Has nothing to do with the Dragon Ball character of the same name, though I don't blame you for thinking as such.
