Shinrei

Shinrei is an ex-member of the Goyousei who has great loyalty to the Mibu Clan. He hates Kyo for abandoning the Mibu and ruining their plan for domination. He dislikes Hotaru (Keikoku), as the latter always provokes him and has no loyalty to the Mibu. The eldest son of a noble man of the Mibu and his official wife, Shinrei was the rightful heir of his branch. He has been taught to be totally loyal to the Mibu and has devoted his life to them. He has a cold and serious personality; though sometimes he loses his cool easily, especially if he is provoked by Hotaru (Keikoku), his rival and half-brother. Shinrei was told about his relation to Hotaru in his youth.

After learning that fact, he has kept his eyes on his little brother from the shadows. It was Shinrei who stopped his father from sending assassins to kill Hotaru and who secretly helped Hotaru participate in the competition for a position in the Goyousei (which is only open to competitors from noble families of the Mibu). However, he never showed himself as Hotaru's brother until his last fight with Hotaru and Kyo. Despite their contradiction and contrast, Shinrei and Hotaru hold a strong bond between them, but they consider each other as siblings and rivals. After their final bout, their bond becomes stronger and the two even start to fight together.

Shinrei fights with a "dancing sword technique" as his fight looks much like a dance. The technique is dangerous and nearly overwhelms Kyo. Being of incredible skill, Shinrei's abilities increase as the skills of his opponent increase. The technique is based on a seemingly simple, but rather impossible, practice. He first slashes, and his opponent moves accordingly to counter his attack. While his opponent is moving to counter his attack, Shinrei redirects his attack with near impossible speed so that although it appears as if his opponent is blocking, that opponent will actually get hit instead. This is soon countered by Kyo who simply closes his eyes and "senses" Shinrei's blade.
