Undertale: The Soul of Compassion

The Underground was no stranger to humans. Six humans, all children of varying ages, have fallen down, and have perished.

Those unfortunate souls were either too naïve or did not understand that every action has consequences. Some were overconfident. Some...were never taught the concept of right and wrong.

One day, however, a human adult, through unfortunate circumstances, also found herself in the Underground. She has far more life experience than any of her predecessors, and as a result, is far more cautious. She too, however, can be somewhat naïve and idealistic, but knows when it's time to call it quits and live to fight another day.

She forms unlikely friendships, from two lovable skeletons...to an ambitious ghost turned robot and an awkward scientist...even a young human girl with enough determination to save two worlds.

When she finds herself falling for one of her friends, she starts to question what she truly wants. Does she really want to leave the Underground or is she willing to stay behind with the one she loves and wait for someone better suited for the job of liberation?

Better yet, will she and her friends even make it out alive?
