Life
The life radical and the life kanji are the same, so hopefully you now just know them both.
Study your radicals and you'll read good.
せい, しょう
い, なま, う, は, き
None
You can save life or take it away with your new saber (せい). This is the saber you got from doing the correct thing (remember?), and now you need to figure out how to use it with this life. So what do you do?
Imagine having someone's life in the palm of your hands. It's up to you whether you protect it with your saber or... well... do the other thing sabers are for.
