Gentle
You've been ordered to spear this tree but you decide to be really gentle instead.
Imagine gently poking the tree with your spear. You glance around nervously, hoping no one notices how easy on it you're being.
じゅう, にゅう

None
You're being really gentle to the tree when a jewel (じゅう) falls out of its branches and hits you on the head.
The jewel has a little note on it, "Thank you for being gentle." Did... did the tree just reward you for being gentle?!
