Current Team :Team 8 (Kurenai Yuhi, Shino Aburame, Hinata Hyuga, Kiba Inuzuka)
Yuhi Kurenai is the Jonin in charge of Team 8, which consists of Kiba Inuzuka, Shino Aburame and Hinata Hyuga. Relatively little is known about her, other than the fact that she only became a Jonin recently. She cares a lot for her students and develops a strong bond with them, particularly Hinata. She also seems to have some sort of relationship with her fellow Jonin Asuma Sarutobi, but neither will admit to anything.
While she has a close bond with all of her students, she seems to especially favor Hinata. Kurenai knows how Hinata is viewed by her father, even though she is technically the heiress of the clan since she is the eldest child. When Kurenai went to inform Hinata's father, Hiashi Hyuga, that Hinata might end up being killed during a mission, he told her that he didn't care since she was even weaker than her sister, who is five years younger. Hinata overheard the conversation. She is also somewhat aware of her student's tremendous infatuation with Naruto Uzumaki. When Hinata tries to offer Naruto some medicine after his fight with Kiba, it is Kurenai that convinces him to take it.
Hints throughout the series also suggest that she has a romantic relationship with Asuma. The two tend to be seen together often, so they clearly enjoy each other's company, and she blushed on one occasion when Kakashi Hatake suggested a connection between the two.
During the Chunin Exam, Kurenai watches her pupils from the sidelines. After Shino's battle, she comments on how it suddenly got cold in the room, in reference to his rather unmerciful defeat of Zaku Abumi. During Kiba's fight with Naruto, she thinks to herself (and to Kakashi) that Naruto can't possibly beat Kiba, only to be surprised over and over as Naruto takes everything Kiba throws at him. During Hinata's fight with Neji Hyuga, she remembers the terrible relationship Hinata has with her father. She also notes the stark contrast between the current Hinata, who refused to give up, and the former Hinata, who would give up easily. When Neji is sent into a blind rage by a comment of Hinata's, she helps stop him along with every other Jonin present, save for Asuma.
Just before their battle with the Akatsuki members and , both Kurenai and Asuma are seen at a dumpling shop. Kakashi happens to notice and comments that they are acting friendly as usual. Kurenai blushes and protests at this, saying that it was Anko that wanted the dumplings. Asuma changes the subject quickly by asking Kakashi why he's there, and notes that Kakashi doesn't like sweets.
During her and Asuma's brief battle with Itachi and Kisame, Kurenai manages to trap Itachi in her Demonic Illusion: Tree Bind Death, only to have him reverse it with his Sharingan. Itachi mocks her for the low level of her genjutsu techniques compared to his seeming mastery and yet seemingly hesitates long enough for her to escape. After Asuma is injured in his own fight with Kisame, Kakashi comes to the rescue.
Kurenai makes her Part II appearance in chapter 313 of the manga. Asuma visits Kakashi in the hospital, saying he has something he wants to talk about. Kurenai shows up just before they can start, looking for Asuma. When Kakashi asks her if she needs something, she says no. She simply came because she had heard Asuma was there. When Kakashi asks Asuma to continue, Asuma hesitates and says he'll talk to Kakashi later when they have more time. Both Kurenai and Asuma then leave together, leaving Kakashi even more curious about what Asuma wanted to talk about.
As Asuma and his team leaves to hunt for Akatsuki, Kurenai looks on from her apartment, giving a curious yet uncertain gaze.
