Okusama wa Mahou Shoujo Episode 5
Asaba (Ureshiko's hubby) asks Tatsumi to do some research for him for a project and maybe he'll agree to work with his company. Meanwhile, Sayaka decides she wants to be more grown-up and transforms herself into an older girl and hangs out with Tatsumi for awhile (not revealing who she really is). Ureshiko doesn't do much in this episode...
Yaaahhh... that's pretty much it. Not really much happened in this one and it was a little slower paced than other episodes. Sayaka was pretty cute as a teenager and actually acted a lot more mature for once as well. More Ureshiko next time please!
