Show your love of erotic manga and anime, and disdain of social conventions, with a T-shirt!
Anime or manga T-shirts, like band T-shirts, are a popular way of announcing to the rest of the world your interests and how you identify yourself.
No longer is that an issue, as an ahegao (the name given to faces showing unbridled lust in anime and manga) clothing range allows wearers to show their predilections, and look good, or more likely creepy, doing it.
Whether the clothes count as NSFW or even not safe for wearing outside the house, is up to you.
