Who was the main character designer for Fire Emblem: Three Houses?

The main character designer for Fire Emblem: Three Houses was Chinatsu Kurahana.

Kurahana shaped the game’s distinctive character designs, including the visual identities of Byleth, Edelgard, Dimitri, Claude, and the students at Garreg Mach Monastery. Her work helped give Three Houses a more fashion-conscious and contemporary appearance while retaining the series’ fantasy setting and military themes.

She worked with the broader art team, including Mao Yamanaka, who is also credited as an artist on the game. That shared credit does not change the answer to this question: Kurahana is specifically identified as the main character designer. She later contributed to related Fire Emblem projects, including character design work associated with Three Hopes.

Several distractors come from other Fire Emblem titles or artists. Hidari is strongly associated with Fire Emblem Echoes: Shadows of Valentia, Senri Kita worked on earlier series entries, and Yusuke Kozaki designed characters for Fire Emblem Awakening and Fates. Byleth, meanwhile, is a character designed by Kurahana—not the designer’s name.
