Backside Smiles (バックスマイル, Bakkusumairu, lit. "Back Smile") are enemies featured in killer7. They are a variety of Heaven Smile which first appear at the KAKU Building during the second half of Target01: Sunset.

Backside Smiles are unique in that they appear to float several feet above the ground, unlike most kinds of Heaven Smile. They are virtually indestructible; however, if the player repeatedly shoots the sickles on their wrists enough, they will spin round, turning their back to the Smiths and exposing a vulnerable tumour-like growth on their back. Shooting this weak point will kill them instantly.

Aim for its wings. What a fool for showing its rear to the enemy. Just aim for the weak point, and it'll be over in an instant. In the name of Harman...
