Bleach

Bleach is a fantasy anime about a teenager named ichigo kurosaki(voiced by johnny yong bosch...ONE OF THE POWER RANGERS FROM THE FIRST POWER RANGERS SERIES) and his power to see ghosts. one day she see's a girl in a black hakama who is suprised as no human should see her. after getting attacked by a creature called a hollow, the girl while injured tries to give a bit of her power to ichigo, but suddenly is shocked that all her power is taken and ichigo uses said power to fight the hollow. During the course of the series ichigo loses his powers and has to find a way to get his powers back, and some ex soul reaper told him of a way that involved him being in his normal spirit form but trying to search for his powers deep inside him. Because of this method ichigo becomes part hollow and has to fight to maintain his good side or give in and let the hollow side slaughter everything around him even his loved one's. Bleach while a fantasy anime shows situations in life where you may have to do something similar, basically telling us while the answer may not be the best, they don't care and will push forward. this is my example of key concept 2
