Milly Thompson works as a Bernardelli agent alongside Meryl, serving as her assistant and close friend. Despite being physically taller than Meryl, she deeply respects her senior and consistently calls her "senpai" (or "Ma'am" in English)—a genuine term of respect that shows where her loyalties lie.
She's got surprising physical strength, though she often comes across as spacey or a bit simple. Don't let that fool you though; Milly's got a genuinely good heart and an optimistic outlook that's hard to shake. The easygoing act can drop fast if someone disrespects her family or—notably—wastes food, especially pudding. When that happens, she's every bit as hotheaded as Meryl.
There's more going on in her head than she lets on. She's an accomplished chess player, which hints at buried intelligence beneath the ditzy exterior. She does have a weakness for drinking too much, and things can get a little messy when she does.
Milly actually figured out that Vash was the legendary Stampede before Meryl did, though she seemed genuinely shocked that her hunch turned out to be right. She comes from a huge family and keeps up with them through constant letters—something she's branded as "The Milly Monthly."
Perhaps her most improbable trait: she somehow conceals an enormous concussion gun under her coat. The weapon fires X-shaped claw projectiles with enough force to flip trucks. She's proud enough of this arsenal to call herself "Stun-gun Milly."
