Bc he is the antithesis of our actual MC.
Katsuya is the embodiment of a generic, Mary Sue Shonen protagonist. Everyone looks to him as a leader bc it's a generic shonen trope.
- He being constantly surrounded by a harem at all times, generic trope.
- Him getting an "unexplainable" power up in a life or death situation, another generic trope.
- Rescuing a random stranger who happens to be a girl, you guessed it another generic Shonen trope
It's actually a major reason years back that I followed and still read this story today. The difference in character is so apparent thanks to how vanilla Katsuya is in this story.
