Local Heroes. From my understanding the idea of Local Heroes is that they're meant to specifically represent the culture of the area such as their historical sites or local industries to promote the community or generally advertise things like recycling, traffic safety, or other community efforts.
Kizuna Red would most likely just be a cosplay though given the vocational school seems proud of the mangaka they could very well do a promotional event with a pro cosplay of Kizuna Red.
