Shimakaze-san, the everyday Office Lady

Are you... Shimakaze-chan!? It's been a while~!

Oh~?

You know, you used to wear all that risque clothing and say "Faster! Faster!" all the time, but you're like, a proper office lady now, eh?

Stop talking about that time! That was the peak of my youthful energy! My dark history!! Dark history (黒歴史) is a slang originated from the anime "Turn-A Gundam". It is referring to a part of history one wants to forget.
