Hotto Kaji possesses a nonchalant demeanor that often makes him come across as aloof or indifferent to the world around him. He's the kind of person who wouldn't bat an eye if chaos erupted in his surroundings. This laid-back attitude, however, is both a strength and a weakness.

1. Observant: 

Despite his apparent lack of concern, Hotto is highly observant. He often notices details that others might overlook. This is a trait that serves him well in battle, allowing him to anticipate an opponent's moves or spot weaknesses that he can exploit.

2. Short-Tempered: 

While he may seem indifferent, it doesn't take much to get under Hotto's skin. He's easily irritated, especially by those he perceives as foolish or by trivial matters that disrupt his day. When annoyed, his fiery temperament (pun intended) often results in sharp retorts or impulsive actions.

3. Independent: 

Growing up in the shadow of tragedies and challenges, Hotto has learned to rely primarily on himself. This has made him fiercely independent, often preferring to tackle problems on his own rather than seeking assistance.

4. Loyal: 

For those who manage to break through his indifferent facade and earn his trust, Hotto is fiercely loyal. He may not wear his heart on his sleeve, but he would go to great lengths to protect and support his loved ones.

5. Strategic Thinker: 

Hotto's nonchalance isn't born out of ignorance. He often uses it as a strategy, letting others underestimate him. He's adept at planning several steps ahead, ensuring he always has the upper hand, especially in battles.

6. Sarcastic Wit: 

Hotto's humor tends towards the sarcastic. He often quips and makes snide remarks, especially when annoyed. Though his sarcasm might rub some the wrong way, those who know him understand it's just part of his charm.

7. Dislike for Injustice: 

Though he might seem indifferent to many things, Hotto has a deep-seated disdain for injustice. He won't stand for bullies or those who abuse their power, and he's been known to intervene, even if it means drawing attention to himself.

8. Reserved Emotions: 

Hotto rarely lets his true emotions show. He's constructed walls around himself as a protective mechanism. This makes him hard to read, and only a few, like his brother Rakuda, can truly decipher what he's feeling.

9. Reluctant Leader: 

Despite his nonchalance, Hotto possesses natural leadership qualities. However, he's a reluctant leader, often shying away from positions of power or responsibility unless absolutely necessary.

10. Stubborn: 

Once Hotto sets his mind to something, it's nearly impossible to deter him. He'll pursue his goals with single-minded determination, even if the odds are stacked against him.

In conclusion, beneath Hotto Kaji's indifferent exterior lies a complex web of loyalty, passion, and strategic intelligence. While his nonchalance might be off-putting to some, it's a testament to his strength and resilience in the face of life's many challenges.
