This is a new sweet being offered by Family Mart that is made up of a combination of chocolate cake, vanilla cake and banana cream. It can be yours if you live within traveling distance of a Family Mart in the Okinawa or Hokkaido area and have 157 yen (about $1.60) burning a whole in your pocket and a yen (no pun intended) for a carb and sugar bomb.
It may seem rather unassuming, but, when I saw this picture, I thought, "you're getting very sleepy". Either this is meant to be a delicious Swiss-cake-roll-type treat from Family Mart or an implement of potential evil with which you can hypnotize people and convince them to do your bidding. Perhaps the people at Family Mart would say, "why can't it be both?" Indeed.
