Ore no Imouto ga Konnani Kawaii Wake ga Nai – 10
「俺の妹がこんなにコスプレなわけがない」 (Ore no Imouto ga Konnani Kosupure na Wake ga Nai)
“There’s No Way My Sister’s This Into Cosplay”
I felt a bit shortchanged by an episode title that clearly suggested a certain younger sister would be doing some cosplaying, but where Kirino didn’t dress up as Meruru (or Rinko, lol), Kanako of all people made up for it. Things would have never gotten there if it wasn’t thanks to Ayase, whom I’m surprised Kyousuke will still meet up with and help out after that… incident.
