Japanese game publisher D3 Puplisher Publisher has posted this short clip of someone wearing a hug pillow cover case of Dream Club character Mian as she walks through what looks like Tokyo's Shibuya.
The case then visits D3P's offices. As it would. Dream Club is a Japan-only virtual hostess game for the Xbox 360. Hug pillows are body pillows that are used for hugging.
