We went to `Pantoproject`. It is the company that makes the items of deer. There are something to drink, face mask, supplement, and so on. They are made of blood of deer. They have many effects like tonic and vasodilation. In Pantoproject, they collect blood of deer, and process them. I drank blood of deer. It was not so tasty. However, after drinking, my body became hot. Therefore, I bought it for my father.

Then, we studied the history of symbiosis of human and deer. I learned that human use all part of deer. I thought that human give many kind of mercy from deer for a long time.
