Usuke Devil is a nick name of a Japanese fashionista and model, he is quite popular in Japan and Asia. Usuke`s instagram has more than 100,000 followers, I guess most of them are girls. Asian people love to have big eyes, high nose, white skin, V-line face, he has them all. And I think this is the main reason he becomes famous.
If you are spending hours at the gym lifting to get a toned abs, being skinny is one of Asian trends among teens. So next time if you like to date an Asian girl who is not living in America, you know what you should look like to attract her ;)
