The walls of the stairwells in Akihabara's multi-storied stores are littered with game and anime posters. Whether one is going up or down, he or she can't help but notice anything that stands out, making these narrow areas the perfect place to advertise to the prospective consumer. Alchemist decided to go one step further and hang an actual promotional item - in this case, a Suzunone Seven oppai mouse pad. Luckily for us, the developer's marketing department saw this as an opportunity to capture some interesting promotional video material. The result is this clip that features hidden camera footage of passers-by reacting to the free-to-touch display.

note: The "action" starts at around a minute in, so feel free to skip ahead if you don't free like sitting through some close-ups of the mouse pad.
