Rise of the Red Ninjas

I'm curious about the creative process behind designing the ninjas and their skills — did the author draw from traditional ninja stories or invent everything from scratch?

Their teamwork and loyalty really stood out to me, but I wonder if the author based it on personal experiences or observations of kids working together.

The pacing kept me engaged, but I noticed the mix of intense ninja battles and funny banter — was that a deliberate choice to keep young readers hooked?
