Kurama (蔵馬, Kurama), known as Shuichi Minamino (南野秀一, Minamino Shūichi) in the human world, is a demon who fused himself with an unborn human child. Kurama is originally a cold-hearted demon thief who becomes injured by a bounty hunter. He fuses himself to the unborn child of Shiori Minamino, and plans to use the body to recover. After living as a human, he eventually becomes attached to his mother and his lifestyle, which causes him to continue living his human life as Shiori's son. He is highly protective of those he cares about and is often merciless to anyone that poses them a threat, a shift in his usually friendly manner. His human form is voiced by Megumi Ogata in Japanese media and John Burgmeier in the Funimation dub. His demon form is voiced by Shigeru Nakahara in Japanese media.
Kurama is generally regarded as calm and level-headed compared to other members of the group. His analytical nature is present in battle where he prefers to study the strengths and weaknesses of his opponents before devising a strategy of his own. Kurama's special ability is that he can turn plants into deadly weapons by manipulating his energy into that plant. Kurama has complete control over any Human Realm plant and has some control over Demon Realm plants. His main weapon is a Rose Whip (ローズ ウイップ/薔薇棘鞭刃, Bara Shibenjin, lit. Rose Thorny Whip-blade), which is able to easily cut through steel. Under certain circumstances, he is able to change into his demon form, whose personality has split from the human Kurama. His demon form is much stronger and he has better control over Demon plants. Kurama eventually decides to never return to this form again and remain completely human.
