In what can only be described as inspired advertising, mobile game World of Tanks Blitz is promoting itself in Japan with a dating sim browser game entitled Tank Head Girl ~I Want to See Your Smile~ which encourages players to step into the shoes of a high school boy attempting to ask out a girl with a FV214 Conqueror tank on her head.
In Tank Head Girl ~I Want to See Your Smile~, the object of your affection is Ayano Kintou (voiced by Ryoko Shiraishi), a girl with a strong sense of justice and a mania for military weaponry who always wears a tank mask in public, earning her the nickname of “Tank Head Girl”.
You can check out the game (in Japanese) at the official promotional web page here.
