About Sarutobi Asuma

From Wikipedia
Asuma Sarutobi is the leader of Team 10 and son of the Third Hokage. He had a falling out with his father when he was younger, and briefly left Konohagakure in protest. The two had not completely reconciled by the time of the Third's death. Asuma is usually seen smoking a cigarette, but will temporarily drop the habit when something is bothering him, such as when his father died. Among all his students, Asuma shares a particularly close relationship with Shikamaru Nara, and the two frequently play shogi or the game "go" together. Asuma frequently appears alongside Kurenai Yuhi, leading many characters to assume the two are a couple. Both deny this and promptly try to change the subject whenever it is brought up. During Part II of the series, however, Kurenai is revealed to be pregnant with Asuma's child, making their relationship clear. In battle, Asuma wields unique brass knuckles equipped with blades that can be infused with his chakra. When infused with his wind-based chakra, Asuma can extend the blades' length and easily pierce through rock. After Asuma is killed by Hidan, a member of the criminal organization Akatsuki, these knuckles fall into Shikamaru's possession, and he uses them to defeat Hidan and avenge Asuma. Asuma's seiyu in the Japanese anime is Juurouta Kosugi, and he is voiced by Doug Erholtz in the English adaptation.

About Yuhi Kurenai

From Wikipedia
Kurenai Yuhi is the leader of Team 8. Of all her students, Kurenai is closest with Hinata, acting as a surrogate parent in the absence of Hinata's father, and helping Hinata overcome her weaknesses. Whenever Kurenai appears in the series, she is regularly accompanied by Asuma Sarutobi. Because of this, many other characters assume them to be a couple, though they both deny this. During Part II of the series, Kurenai is revealed to be pregnant with Asuma's child, making their relationship clear. In battle she specializes in casting illusions, and is shown to be particularly skilled with illusions involving plants. In the Japanese anime, her seiyuu is Rumi Ochiai. In the English adaptation of the anime, she was voiced by Saffron Henderson in episode three, and Mary Elizabeth McGlynn in all subsequent appearances.
