Mechanical Marie(2020)

Kikaijikake no Marie

He was a boy. She was a robot. Well...not really. In all actuality, Marie is completely, totally, 100 percent human, but because her strange new employer seemingly despises humans, the powers-that-be are paying a handsome sum for her to pretend she's the latest and greatest android while protecting said eccentric master from the seemingly endless attempts on his life. Which is fine, but they forgot to mention one tiny seemingly insignificant detail-this dude absolutely dotes on inanimate objects like Marie can't believe. She's not sure what will kill her first, the assassins or his affections...?
