Tamotsu Denkigai is just another otaku, prowling the streets of Akihabara for elusive rare figurines and other treasures. However, the streets of Akihabara aren't what they used to be - pretty cosplayers are ripping each other's clothes off!

The cultural cleansing of Akiba is turning into something more closely resembling an ethnic cleansing operation, and Akiba residents are being rounded up by the police. Can Matome and Tamotsu defeat the mastermind and save the day?
