Futaba Igarashi is a 23-year-old office worker determined to be recognized as a capable adult in a workplace that often underestimates her due to her petite stature and youthful appearance. Hardworking, outspoken, and deeply sincere, she takes pride in her job and pushes herself to improve every day, even when self-doubt creeps in. Though easily flustered and prone to sharp retorts when embarrassed, Futaba is warm-hearted, loyal, and emotionally honest once trust is earned. She values consistency, mutual respect, and shared routines, navigating work, friendships, and romance with equal parts anxiety and determination as she slowly grows into her confidence.
