“What’s an “Animus”?’ asked Mad Dog.Literally, it means “animating spirit” – that’s the essence of your core being, the spirit that defines you as a person,' answered Yazuki. 'But it can also mean “animosity” which is why the animal shadows only usually come out in confrontational situations. For centuries, Ninja have looked to the earth for inspiration in ways to live and fight. This is why you see us all giving off animal shadows. We each study the species that mean most to us. We each have an “Animus” that is unique...”

“Think about Praying Mantis. The deadliest ninja predator. Why isn't his animus a lion or a polar bear - two of the most successful killing machines in the animal kingdom? The answer is that these animals would not be right for him. Think how a praying mantis is invisible on a leaf, how they are carnivores who will devour their own species. The female will even eat her own partner once they've mated and, as hatchlings, their first meal is often one of their own siblings. These are the things that matter to Praying Mantis - and if you study his attributes, they are elements that will help you defeat him.”

“Just as I was thinking I would never find my animus, I caught sight of my shadow and laughed out loud. I'd thrown myself onto the floor in frustration - my head resting on one arm and waving the other to cool myself down. There on the wall was the perfectly formed shadow of a cat, curled up - with a swishing tail! ...I even heard myself purr!”

“When all else fails, when you hit a brick wall, let the enemy reveal themselves by giving them what they're looking for.”

“What don’t we realize is that we are a strange and forbidding species to wild animals. We fill them with fear. They avoid us as much as possible. It took centuries to still the fear in some pliable animals – domestication it’s called – but most cannot get over their fear, and I doubt they ever will. When wild animals fight us, it is out of sheer desperation. They fight when they feel they have no other way out.”

“We're only passers-by, and all you can do is love what you have in your life. A person has to fight the meanness that sometimes comes with you when you're born, sometimes grows if you aren't in lucky surroundings. It's our challenge to fend it off, leave it behind us choking and gasping for breath in the mud. It's our task to seek out something with truth for us, no matter if there is a hundred-mile obstacle course in the way, or a ramshackle old farmhouse that binds and binds.”

“And we mean to treat you all,' added Lydia, 'but you must lend us the money, for we have just spent ours at the shop out there.”
