Kanako is well educated in the ways of science. Ass crack hair traps oily secretions that carry scent, while also providing an environment for bacteria that consume these oils and generate yet more smells. Ancient ancestors use this odor to mark their territory and attract mate so it is historically advantageous to leave butt crack hair. Butt hair also serves to reduce friction and chafing as we move around. By trapping the aforementioned stinky oils, hairs ensure that our cracks remain nicely lubricated, thereby protecting us from irritation and rashes.
