Natsu shares the closest friendship with Lucy among all other members of Fairy Tail. Their deep bond stems from the fact that he had been responsible for inviting and bringing her to the guild, and eventually teamed up with her to form Team Natsu. While Lucy often gets irked oleh Natsu's destructive and impulsive nature, she is also greatly amused oleh his childish antics. Much to her chagrin, Natsu frequently drops oleh Lucy's halaman awal unannounced, and once even fell asleep on her bed, waiting for her. He believes Lucy is a strong person even if she herself doubts her abilities.
