Which Anime With Good Plot Has Deep Themes?

When I have a pen in my hand and paper before me, I think I want to write something to cast every despair in my pathetic life away. I have a figure of a depressed guy whose fate is too much: saving the world. He is not stupid nor even smart, he is not ugly nor even good looking. He is just a nijikon (A person who loves an anime character more than the real one) like me. He once thought to give up on life, but an event changes his life. I'm sure you guys start guessing how the story goes, but too bad, this one is different than the others.

All Seo-yeon ever wanted was to live freely. Away from the fear that stayed buried deep inside her. She hated being called the monster she was and yearned to live away from reality, no matter how much ignorant it'd make her. She believed that she could make a present that allowed her to cherish the various aspects of life. She was lost in her world and never wished to step out of it until the day she meets the guy of her fate. An unalarmed turn takes place and leaves a deep scar on her chest. Does his presence help her face off the brutal past that she's been trying to run away from? Or does it lead her to a door that directs her to an event that she could have never imagined of?

Our protagonist was living under the mirage of a false beautiful and happy life though in reality the world of that time was pretty corrupted by the evil leaders and higher ups. But one day the mirage broke when his beloved father killed his mother brutally in front of him. He then out of anger and sense of revenge also killed his evil father. And on that day he took an oath to annihilate the evils. But for that he didn't choose the righteous heroic path rather he believed "Only a Devil can annihilate evils." and he charged towards his goal of being a devil. To fulfill that goal he learned all kinds of fighting styles, martial arts, mastery of weaponry and with his smart, strategic, manipulative mind he started eliminating the evils a.k.a the leaders and higher ups. He also formed a small but most dealy group called "THE DEVILS" and stood against the whole world. The novel contains action, mystery solving, blood shed, assasination, humour, manipulative powerful badass protagonist etc. How will things end up for our devil disguised in the human avatar, will he survive against the world or will he fall by the hands of any angel will be revealed…….
