Milly Thompson

Despite physically towering over Meryl, Milly looks up to her and always refers to her in a respectful manner. She appears rather simple, but has a kind heart and also reveals a strength of character and genuine optimism. Milly comes from a very large family, and writes letters to them constantly (known as "The Milly Monthly"). Milly manages to hide a very heavy concussion gun, referred to as a "stun-gun", under her coat. The shots, which pop out into the shape of an X-shaped claw, are so powerful they can even knock over trucks. From Trigun Wiki
