A yokai-flea who is InuYasha's source of information. He usually runs away from dangerous situations. He was initially charged with protecting the remains/gravesite of InuYasha's father which held the Tessaiga. The Grave was hidden inside the black pearl in InuYasha's right eye and was opened during his first run-in with his elder brother, Sesshoumaru. Myouga also enjoys drinking yokai blood, and actually saves InuYasha's life at one point by drinking the poison out of his blood. Because of that, he often gets slapped by InuYasha (and sometimes by Kagome too), but never dies from it since he's immortal.
