Why do Japanese anime heroes almost always have hedgehog heads?

This shows that your animation experience is not enough. The protagonist has a flat head, long hair, 37 points and a lot of messy hairstyles. Yes Where is the hedgehog head?

There are many movies that are not hedgehog-headed and masculine. Far away, it is said that the new fan in July, the legendary legend of the brave (this is enough blood), the delusion of the student union, the three sisters with super vitality (these two languages are a mess), the playmate of the cat's ear mother (big piece of meat), the owl goddess (big piece of meat *2), the supernatural college at the end of the century (sf works), and the male pig is not a hedgehog. There are many examples that I won't bother to give.

In July, the male pig left in the college silent record and digital baby combination war was hedgehog head. Of course, there were hedgehog heads in basara during the Warring States Period. It is not normal for so many men not to have hedgehog heads.
