[Supplementary explanation]
This drawing style, which can be frequently seen on the Internet these days, is produced and distributed by Irasutoya, a Japanese illustration site run by illustrator Takashi Mifune.
Irasutoya is a company that opened in 2012 and has gained many users with its unconventional strategy of allowing up to 20 images to be used for free for commercial purposes.
It captures various situations and draws them one by one in detail, so there are many variations. It has a round painting style and the font is easy to use, so it has the advantage of being easy to use widely without feeling burdened.
So these images were used very widely throughout Japan, from companies to government offices.
At present, it is overwhelmingly outperforming competing sites. You can even find this image used in Korea.
Irasutoya sometimes updates interesting situations or impressive incidents by receiving requests from users, and accepts commercial orders for a fee.
In addition, the company is engaged in various additional businesses, such as releasing messenger stickers using this image and figures modeled after the character.
