Mary Cagle, also known as Cube Watermelon, is an American webcomic artist known for creating Kiwi Blitz, Let's Speak English, and Sleepless Domain.
Cagle was raised in Corpus Christi, Texas and developed a strong interest in Japanese pop-culture, including both older and more modern anime and video games.
The webcomic, titled Let's Speak English, shows Cagle dealing with subjects such as Japanese pop-culture, toilets, thin walls, and the language barrier.
The story, set in a city that is invaded by malicious monsters on a nightly basis, features a group of magical girls and their interpersonal issues.
[15] In a review of the first collected volume, Publishers Weekly praised the comic for its darker take on the magical girl genre, noting its exploration of themes such as survivor's guilt, power, and exploitation.
