After introducing herself as Keima's sister,
Elsea follows Keima home, moves in and tries to act like a real little sister would. Keima on the other hand refuses to accept her. Ultimately he gives in after Elsea completes the requirements that he believes a little sister must have.
After the sister issue is settled, the second target appears: Mio Aoyama, the daughter of Aoyama Central Industries' president. To Elsea this seems like a hard capture, but Keima begs to differ. He knows that behind the tough exterior there's a soft and innocent side. So now it's off to plan the best route for capture.
