Koro is made up of 4 parts easy parts. If you can remember these 4 parts, you can memorize this kanji very quickly.
For the left side, the top part is someone running on a tree, the bottom part. So, for the left side, think about Crouching Tiger Hidden Dragon or other such memorable movies that deal with people flying on the tops of trees and you will get it with ease.
For the right side of the kanji, the top part if a person on his/her hands and knees on top of a table facing the left side of the kanji next to the guy flying on top of the tree. Notice how the person's head is missing, that is because the flying man chopped his/her head off.
