"I'm the only one who can research the mystery of this book. Take care of yourself, Miaka. Your big brother will rescue you!"

—Keisuke in Fushigi Yuugi: Volume 3, Chapter 17Keisuke Yuuki (夕城 圭介 Yūki Keisuke) is Miaka Yuki's older brother in Fushigi Yuugi: The Mysterious Play. He conducts research surrounding the history of The Universe of the Four Gods while he reads along as his sister's adventure inside the book unfolds.

Appearance

Keisuke is depicted as a typical twenty year-old in school, dressing in mostly hoodies, t-shirts, and the occasional turtleneck and casual button up with jeans. On occasions, he dresses up his outfits with a nice jacket or blazer. On the taller side, he has a slim build and is shown to have light brown hair and dark grey/black eyes.

Personality

Keisuke is selfless, brave, and surprisingly grounded for being a humorous and easy-going college student. His genuine attitude and comedic jokes make him well-liked and respected by others.

Keisuke wears his emotions on his sleeve as he openly cries over character deaths inside the book and in reality. He is also shown to get obsessive and fan-like, especially when Tamahome arrives in the real-world and he begins to hero-worship him.

He is very aware of his limits and abilities in the face of powerful celestial warriors and beast gods. He understands that his strength lies in his intellect.

Story

Fushigi Yuugi: The Mysterious Play

Keisuke first makes his appearance at the dinner table following a full day of college classes at Seinan University. When their mother berates Miaka for her low test scores, an understanding Keisuke assures Miaka that “I wouldn’t tell you [your scores were bad] even if I knew.”

Following Miaka's disappearance inside the book, Keisuke joins Yui's search for her and uses his mother’s trust in him to come up with an excuse for his sister’s absence.

When Miaka returns, Keisuke is not quick to believe her tale about The Universe of the Four Gods, however, he still cautions her even in his doubt. It is not until he watches her disappear into the book at the National Library that he is convinced of its power.

Keisuke defers to researching the history of the book, playing detective as he teams up with his best friend, Kajiwara Tetsuya.

Relationships

Miaka Yuki

Keisuke's dynamic Miaka is a typical sibling one (teasing, sarcasm, etc.). But, from the beginning, there is an air of sympathy around Keisuke‘s interactions with Miaka. He finds himself fulfilling the role of their absent father.

Kajiwara Tetsuya

Keisuke and Tetsuya are shown to be best friends. Both humorous in nature, Tetsuya is the cool-headed and skeptical Watson to Keisuke’s inquisitive and dramatic Holmes. Keisuke even has a "spot" in Tetsuya's car and they both share a mutual love of beer.

Trivia

• In the Filipino dub, he was renamed as Kenny.
• Throughout the series, he goes to university and majors in Chinese philosophy.
