Iiwaken is a cute Shiba Inu puppy. His name translates directly as "Excuse Dog".
Iiwaken's owner is a business man who has trouble waking up sometimes. Iiwaken makes his master play with him in the morning, often making his master late for work.
This is okay because Iiwaken will use the Crayon he wears around his neck to write a late excuse for his master.
Iiwaken is also excellent at drawing and, I believe, is also very good at math.
