Tokyo, but I'm a deceitful fox

After traveling to Japan, where demons were rampant, Hoshino Hideyuki became a male fox and was almost slaughtered as game at the beginning.
Fortunately, I awakened to a system that allows me to become stronger by lying.
So, he started by stealing the first lollipop from a little girl on the street, tricking a bad high school girl into jumping around, and then turned a pink skirt into a suit and sold it to a fat-faced uncle, and calculated the time to make the spell fail in the street...
After some experiences, looking at the seventy-two transformations in the skill bar, looking at the flowers in the mirror, charming everyone... The fox put his hands on his hips, shook his tail, and felt that he could do whatever he wanted!
"We are all foxes. What's wrong with following our nature and deceiving people?"
"When cheating, we should be equal. We cheat ordinary people and beautiful girls. Is there any problem?"
"After I tricked the pretty girls, they kept it in mind. Once I failed, they came to me... Wait, no, this is a big problem!"
The boasting stopped abruptly. Looking out the window at the many victims, including the arrogant Yin-Yang Master, the stalker lady, the nymphomaniac scientist, etc., the fox's big fur tail began to wag:
"Don't come over here!"
