What are some light novels where the main character can't feel anything?

I can think of 'Emotionless Hero' where the MC is completely numb to emotions. The plot builds around his journey to regain his feelings.

One possible reason could be a powerful jutsu gone wrong. Maybe he was hit by an enemy's attack that was specifically designed to numb his senses. Another reason might be some kind of psychological trauma. For example, if he witnessed something extremely horrible, his mind might have shut down his ability to feel as a form of self - protection.

One such light novel is 'Sword Art Online'. The MC, Kirito, undergoes significant growth and evolution throughout the story as he faces various challenges and battles.

One such light novel is 'The Dragon's Legacy'. The MC is a powerful dragon and the story follows his adventures and growth.

One such light novel is 'The Ancient Magus' Bride' where the MC is a humanoid spirit. The story is captivating and the non-human MC adds a unique twist.

You could check out 'God's Legacy'. Here, the MC is an ancient god reawakened in a modern world and faces various challenges. The story has a lot of action and mystery.

One such light novel is 'The Solitary Hero'. The MC is isolated in a mysterious world and has to face various challenges alone.

One great light novel with a non - human main character is 'Overlord'. In this story, the main character is Momonga, who is a powerful lich. He gets trapped in the game world he was playing, and his journey to explore and dominate this new reality is really engaging. The story is filled with interesting characters, both friends and foes, and the world - building is quite elaborate.

Maybe he's been cursed by a powerful enemy. In many fanfics, an enemy might use a dark jutsu to take away Naruto's ability to feel. It could be a way to weaken him both physically and mentally.

One such light novel could be 'Divine Chosen'. In this story, the MC is picked by God to fulfill a special mission and embarks on an epic adventure.
