Kodama

According to Japanese legend, a kodama is a peaceful spirit that lives inside certain kinds of trees. Those who have claimed to have seen a kodama describe it as a small white and peaceful ghost that syncs perfectly with Mother Nature. Nevertheless, according to legend, when someone tries to kill a kodoma (or cut down the tree a kodama lives in), the aggressor will be cursed and many bad things will happen to him. There are also claims of human blood coming out of trees inhabited by kodomas if its cut down but none of these rumors have ever been verified.
