Kouga

鋼牙

Kouga, the young leader of a yourouzoku (youkai-wolf tribe), wishes to avenge his fallen comrades who were slaughtered by Kagura, one of Naraku's minions. Though brash and arrogant, he is shrewd enough to flee a fight if he believes he cannot win. He possesses a Shikon shard in each of his legs, which makes him stronger and faster. Although he constantly bickers with InuYasha, the other will lend a hand when one of them is in danger. He considers Kagome his woman, which irritates InuYasha to no end. Koga constantly confesses his love to Kagome, but she does not share his affections, having eyes only for InuYasha. As the series progresses, Koga gradually lets up on his affections for Kagome. Eventually, in chapter 466 of the manga, he leaves her behind with the statement "if InuYasha ever starts getting on your nerves, you can come to me." ("Koga" means "steel fang.")
