Update - The World God Only Knows Chapter 168 - Bath Stop

With Tenri suddenly appeared in front of him with swimsuit, Keima becomes dreadfully shocked. Tenri regained her control her body and suddenly trying to avoid away from Keima by submerging herself into water.

Tenri evaded Keima (Diana struggled with her to gain control)

Diana convinces Tenri to confess to Keima immediately so she can regain her wings and also her powers. It seems that Diana herself has starting to fall for Keima despite his dweebness.

Keima then asked Tenri to do what she should do, but then he remembers about the incident that happened earlier, which then depressed Keima, asking Tenri to get out from the tub. 

Tenri still stays at his home. After getting out from the tub, he met her again. Tenri suddenly asks him, offering him a magic show. While helping her setting up the magic box, Tenri (blushingly) confesses to Keima, saying that she wanted Keima to be like a normal boy, without being a geek in game. Keima thanked her for saying that.He continued watching the show despite his dismay.

P/S - SPM is one more subject left! HAHAHAHAHAHAHAHAHA!
