Kei Okano

Driven by a fierce and tomboyish spirit, this character displays an intense, almost possessive devotion toward Aikawa. Her personality is defined by a bold, energetic nature and an unexpected streak of jealousy whenever others get too close to her close companion. As a key figure in the story's social dynamics, her protective instincts and complex emotional bond with Aikawa drive much of her character development and interpersonal tension.
