No-bullshit assassin - Tradução em português

Quem pode me ajudar com a tradução do termo "no-bullshit" no contexto abaixo?

For me, my alter ego is someone I invented. Her name is Svetlana, and she’s even more of a no-bullshit assassin than I am. She’s who I channel when I go to work and need to slay. She loves rich men, richer women, Italian sports cars, and stilettos, and she definitely has a way with a whip.
