The degree of isolation that Kojiro has with himself has created all of his abilities.
Isolation can have a profound impact on a person's development and capabilities. In the case of Kojiro, his self-imposed isolation has led to the cultivation of unique skills and qualities.
Perhaps through the solitude, he has been able to focus intently on honing his abilities, without the distractions of the outside world. This isolation may have also forced him to rely solely on himself, leading to a greater sense of self-reliance and independence.
However, it is important to note that excessive isolation can also have negative consequences. It can lead to feelings of loneliness, depression, and a lack of social skills. Therefore, it is crucial to find a balance between isolation and social interaction.
In conclusion, while Kojiro's isolation has contributed to the development of his abilities, it is essential to consider the potential drawbacks and ensure that he maintains a healthy lifestyle.
