>Scanty sees the use of having a human companion due to Brief always helping Panty
>Finds her peak specimen after humorous selection process
>To contrast Panty/Brief the romance is actually really wholesome
>Kneesocks gets jealous of onee-san spending too much time with someone else
>confronts Scanty and BF about it

>Episode ends with Kneesocks blushing profusely as Scanty and the BF surround her
