Exchanging tarantula with human might be his best option, but the poor boy didn't think of it. Jason decided to set her humanity back to 100%. This might improve his situation and revert her humanity again. Unfortunately, Jason could not properly see the display though the silk chords. He thought that he deleted the 5 and wrote a 10 but instead he misplaced the cursor and just added a 1. With this, he actually changed 50% with 150% instead of 100%. Without proofreading, Jason committed the change.
After the common white flash, Jason checked out the girl in the middle of the room. He was a bit shocked, when the formerly tiny shop keeper has changed into a huge girl. She must have doubled in size and stand almost 7 feet. Her former much to large tent-like cloth were skin-tight now. Her midriff was fully exposed. Jason felt a big relief, as he realized, that her spider features were reduced a lot.
Mia was almost back to human again. She was standing back on two feet and had two human arms. Her butt was back to a normal size and her facial features were almost completely human again. Jason noticed that she still had 4 big spider legs, which were coming out of her lower back. All 4 ended in a pointy spike. 3 were folded on her back, one was stretched out forwards. With her human hands Mia examined it with a happy grin on her face. There were also smaller spider features like a dark hue of her skin, which were not pitch black as before, but still visible. Beside this, she had sharp fangs and long sharp nails. Ignoring the 4 additional legs, she could be rated as human again. Even if she was about 7 feet tall.
Luckily, he changed the correct percentage and did not increase it to much or select the wrong percentage by accident.
Jason pondered, if she had more "invisible" spider features like poison, shooting spider silk or the ability to climb on wall.
Feeling his first step completed, Jason decided to...
