Demon Slayer: Ghost Hunting Demon

[The male protagonist has no CP+first person+growth and upgrade type+friendship and family orientation+the goal is to kick most people out of their lunch boxes] Tsuki City never thought that he would become the ghost he hated most. His obsession overcame his hatred of ghosts, so that before the obsession was completed, he would want to live more than anyone else. From Spider Mountain, to Infinity Train, to Flower Street and Knife Forging Village, and the final battle, the human heart is gradually recovering. He has been afraid, angry, jealous, and escaped. But in the end, he chose the path he expected - he will use his own life to protect his cherished companions. Even if he becomes a ghost, he will still follow the path of protection. [The protagonist has a sensitive and dark personality and is easily jealous and envious of others, but has a high moral level and is good at patience and self-criticism. He will be relatively weak in the early stage. In the later stage, he will think that he is weak. He thinks that he is strong because he cheated or became a ghost. But in fact, he is very strong. It is probably the final state where he can fight to the death with his complete body. However, his inner thoughts are more deceptive. In fact, the protagonist is also very talented. ]
