Hunter x Hunter

Killua initially appears as a calm and reserved individual, possessing exceptional intelligence and formidable fighting skills honed through rigorous training within the Zoldyck family. During the Hunter Exam, his practical and logical side emerges, along with a touch of humor and sarcasm that reveals his unique sense of humor despite his violent background. As he embarks on his journey with Gon and Krieg, a more human side begins to surface: an internal struggle between his loyalty to his family and a genuine desire for friendship and freedom. Killua is highly independent and quick to assess risks, but he is also sensitive to his friends and demonstrates his emotional loyalty in subtle ways, such as protecting Gon or expressing concern for them. Despite his cool exterior, he possesses a childlike curiosity and a gentle nature, and his emotional vulnerability begins to surface, especially when confronted with family memories or constraints, making him more complex and authentic. Upon returning home, his struggle between familial duty and his desire for freedom becomes evident, but he ultimately chooses friendship and connection with others over blind loyalty to his family. Summary: Killua has a dual personality: a skilled and intelligent assassin, yet humane and emotional with his friends. He experiences a constant internal struggle between his violent upbringing and his desire for a normal life. His personality development is clearly evident throughout his journey.
