Eye of Heaven
Shiro (by Yudai)
Byakuya has short black hair, and he is also wearing glasses.
Byakuya is logical and very intelligent. He views a battle as a mental game and believes that the winner is the one who better understands their opponent. He was able to deduce that he could defeat Ikki within 23 moves if Ikki doesn't use Ittou Shura or Ittou Rasetsu. Byakuya is friends with the former Seven Stars Sword King Yudai Moroboshi, who views him as a little bit of a weirdo.
Byakuya joined the 61st Seven Stars Sword Art Festival, reaching the finals before losing to Yudai Moroboshi. Byakuya's ability gave him an edge over other contestants, as he could just teleport them out of the arena upon contact. He was considered part of the "Golden Generation", the three strongest students of Bukyoku Academy, along with Yudai Moroboshi and Momiji Asagi.
Party Crashers Edit
Conclusion of the First Match Edit
Byakuya met his next opponent, Ikki Kurogane, in the bathtub, alongside Nagi Arisuin. He first teases Ikki for already thinking about the semi-finals. Byakuya then starts touching Ikki, being amazed by his body. Yudai, who had just entered, stops Byakuya and scolds him for bothering Ikki. Byakuya gives Ikki and Nagi cups of coffee, which he summons with his Noble Art, God Hand.
Before his match with Ikki, Byakuya speaks with Yudai and tells him that Ikki won't use Ittou Shura or Ittou Rasetsu, because he will need them for his match against Sara Bloodily, and because of this Byakuya will win in 23 moves. Byakuya is proven wrong, when Ikki uses Ittou Rasetsu, winning in 0.8 seconds, as Ikki too knew that he couldn't win without using it. Byakuya is then eliminated from the Festival, because of his loss.
