This is Nao Nagasawa. She's here to unleash fists of fury. And do so at the office, apparently! With Wong Kar-Wai's Grandmaster coming out in Japan, website Movie Enter! thought it would be a good idea for Nao Nagasawa to show off how Chinese martial arts can be used in your daily life—whether that's dealing with creeps, vending machines, or even office romances. The result is a series of amazing GIFs. (You might need to wait a few seconds for them all to load.) But what if you like your co-worker? Well... And after all that fighting, you get really thirsty. Of course, this isn't serious! And as far as movie promotions go, it's pretty clever. Nagasawa is especially good at pulling off the kicks and attacks. She's appeared in Super Sentai (Power Rangers) and Kamen Rider shows since 2002, so no doubt, she's had her share of martial arts training. オフィスでの護身術から恋愛術まで！ [Movie Enter!] To contact the author of this post, write to bashcraftATkotaku.com or find him on Twitter @Brian_Ashcraft.
