Do you know Night Head?
Night Head was a late-night TV series that became a hit in Japan about 30 years ago.
It was also made into anime.
"It's said that we don't use 70% of our brain's capacity.
It's believed that the mysterious power of human being is hidden within.
This unused 70% of the brain is sometimes called the 'Night Head'."
It's exciting?
I heard that the anime is going to be remade.
