Description
Hakua Igarashi is a member of the Third Division of the Defense Force, serving as a peer and contemporary to recruits like Reno Ichikawa. She is the younger sister of Jura Igarashi, who holds the position of Captain of the Second Division. This familial connection to a high-ranking officer is a notable aspect of her background, though she establishes her own identity within the Third Division under Captain Mina Ashiro and Vice-Captain Soshiro Hoshina.

Physically, Hakua is a tall and imposing young woman, a trait that sometimes leads to her being mistaken for male by outside observers. She has long blue or turquoise hair, which she typically sweeps back and secures with a mint-green headband, and she possesses similarly colored eyes. Her build is athletic, contributing to her commanding presence among her fellow soldiers.

Her personality is defined by a loud, lively, and strong-willed nature. Hakua is depicted as being energetic and positive, a trait that proves motivating to those around her. She possesses excellent social skills, quickly befriending other female officers in the division, most notably Kikoru Shinomiya and Akari Minase. The three are often seen training and acting as a trio, demonstrating a strong sense of camaraderie and mutual trust. She is also characterized as a hearty eater and shows a love for animals, as evidenced by her being drawn to Bakko, the pet of Captain Mina Ashiro.

As a member of the Third Division, Hakua participates in major defensive operations. She was involved in the Sagamihara Neutralization Operation, where she helped defeat a Fungal-type kaiju and celebrated the success of the mission with her fellow new recruits. Later, during the Raid on Tachikawa Base, she fought alongside her comrades to defend the installation from Wyvern Kaiju and the powerful humanoid Kaiju No. 10. During this intense battle, she witnessed the transformation of her comrade Kafka Hibino into Kaiju No. 8 as he intervened to save the base. The impact of this event is shown later, as she takes the initiative to text Kafka to thank him directly for saving Tachikawa Base and to wish him well.

Her key relationships are primarily with her fellow members of the Third Division's newest generation. She shares a close friendship with Akari Minase and Kikoru Shinomiya, and their teamwork is a recurring element. She also has a peer relationship with Reno Ichikawa, working hard and growing alongside him as they begin their careers in the Defense Force. The acknowledgment of her sister, Captain Jura Igarashi, by visiting journalists provides a glimpse into her family background, although she appears focused on her duties within her own unit.

In terms of development, Hakua transitions from a new recruit celebrating her first mission to a more seasoned soldier who has survived a major attack on her base. Her gesture of reaching out to Kafka Hibino indicates a growing sense of personal gratitude and solidarity among the division members, moving beyond simply following orders. She demonstrates a capacity for warmth and initiative outside of combat situations.

Regarding her abilities, Hakua is noted for her remarkable proficiency in swordsmanship, specifically kendo. Her skills with the blade are impressive enough to draw praise from journalists observing a training session, highlighting her as a talented close-quarters combatant even among the elite recruits of the Defense Force. While the full extent of her capabilities as a soldier is not exhaustively detailed, her recognized skill in kendo marks her as a capable and dedicated fighter within the Third Division.
