Timewarp-Tan

Timewarp-Tan is a personification off the modified code used for Katawa Shoujo depicted as a Yamaku student.  TimeWarp-Tan gets her name from the "time warp" functions used by Ren'Py.   As Delta wasn';t good at matha dn didn't fully understand how the code would work, peices were added on to the code until it basically did what it was supposed to.  This was invisioned as a young girl that struggled to do her best whenever she was called, which Delta describes as being "quite moé." Timewarp-Tan is also referred to as "The Little Function that Could." 

TimeWarp-Tan in Yamaku

TimeWarp-Tan has been featured in multiple images on the shimmie created and/or uploaded by the Devs.  In these TimeWarp-Tan is shown to be a shorter tha average Yamaku student who experiences a delayed reaction when responding to stimuli of any kind (for instance, not being able to feel being hit by something until several moments later.) 

Sometimes TimeWarp-Tan is shown wearing a maid costume.

There are no canon color picture of TimeWarp-Tan, so her actual hair color and eye color is unknown.
