Jinenji

Jinenji (地念児) is a half-human, half-horse demon who lives in a hut with his human mother. Together they grow a variety of medicinal plants, including some known for being powerful against poisons. He is first seen when Kirara is poisoned by Naraku's shōki and Kagome and InuYasha travel to the village to find a cure. When they find him, they also help to clear his name as he was being falsely blamed for people's deaths in the village purely because of his demon blood. Jinenji is depicted as a gentle giant who is initially scared of humans because of the way the villagers treat him. Upon meeting Kagome, he is surprised to find that she is not frightened by his appearance at all and willingly helps him collect herbs. InuYasha, having also dealt with abuse at the hands of humans when he was a child, attempts to convince Jinenji that he needs to be more forceful towards the villagers, especially after he rescues them from a demon. In the end, Jinenji decides to continue his more gentle approach, giving the men injured during the demon attack the herbs they need to heal themselves. Like InuYasha, Jinenji becomes fully human one day a month. In the animé: during one of these times, Rin visits his home searching for the same cure to heal Jaken, who was poisoned by the saimyoushou while protecting her.
