Episode 11 add's its' own brand of silliness to the series; Girls being Girls.
Yamada & Tanishima still hold fond memories of the CrossDressing from Episode 9 and Tanishima trys to have her way in re-creating this again. During a break, Ghost Stories terrify the girls as to where even Yamada doesn't want to stay in her room alone. She follows our newly found couple to his sisters house and discovers something she's been missing in her life. Its' all for a good purpose so, the girls don't mind/notice a guy in his room. -- trying to study! Oh, did I forget to say that he brought his girl friend with him; now that she understands that he's not leaving her any time soon?
The girls sorta stopped him from going as a guy by dressing-him in girls clothes after dunking him with ... a pot of water! When you first look at who dunked him, you'd swear it was Yamada; till she comes in the room behind her
all in all, a fairly strange series which was silly. 3/5
