Kurona Yasuhisa

Biodata

Background / History

Kurona and her younger twin, Nashiro, lost their biological father while young. Akihiro Kanou subsequently occupied the Yasuhisa estate and used its basement as a secret experimental facility. Unaware of his intentions, the sisters came to regard him as their father 26 42.

Both sought Kanou’s approval through academic achievement, aiming to take first and second place between them. Byakuya’s arrival threatened that goal, explaining why they were hostile toward him even before his shooting-range taunt 43 44.

Original-story fate recalled by Byakuya

The following events are explicitly recalled from the original story, rather than shown occurring to Kurona in the novel’s current timeline 44:

• Artificial ghoul transformation: Kanou used Rize Kamishiro’s kakuhou and kagune to turn both sisters into one-eyed ghouls.
• Defeat by Juuzou Suzuya: While protecting Kanou during the discovery of his laboratory, the twins fought Suzuya and were badly beaten. Nashiro suffered life-threatening injuries.
• Kanou’s abandonment: Kurona sought his help, but he ignored the dying Nashiro.
• Attempt to save Nashiro: Kurona absorbed her sister into her abdomen. Nashiro ultimately merged with her without retaining consciousness or vital signs.

Byakuya questions whether these events can still unfold after his rescue of Rize makes her unlikely to become Kanou’s experimental donor 12 44.

Appearance

Kurona closely resembles Nashiro, with delicate facial features and an almost identical height and build. Their contrasting hair and clothing make them easy to distinguish 20.

• Hair: Black, contrasting with Nashiro’s white hair 20.
• Clothing: Black dress at her introduction 20.
• Height and build: 160 centimeters tall, with a slender figure 20.
• Dominant hand: Left-handed; Nashiro shoots right-handed 21.

Personality

Kurona is reserved with strangers, though initially more approachable than Nashiro. The sisters largely keep to themselves and are usually inseparable. Her competitive streak becomes particularly pronounced when Byakuya surpasses them: she treats his taunt as a challenge and insists that he remember her name as his opponent 20 21 22.

Her ambition is tied to a need for paternal approval. She initially rejects Byakuya’s suggestion that she lacks affection, but later acknowledges that he may be right and explains why their rankings matter so much to her 42 43.

Kurona struggles to admit romantic feelings. She enjoys Byakuya’s compliments while protesting them, becomes jealous of his closeness with Hajime Iba, and repeatedly qualifies her admission that she might like him. She is also strongly self-critical when her mistake causes Nashiro to fail alongside her, but responds to encouragement and resolves to improve 30 31 32 33.
