It has been a trying time for me, as I reflect on the events that have transpired. The news of Kaigaku's betrayal weighs heavily on my heart, causing a deep ache that seems to never fade. As his former teacher and mentor, I cannot help but feel responsible for his actions. Where did I go wrong in guiding him? What could I have done differently to prevent this outcome?

But amidst the darkness that threatens to consume me, there is still a glimmer of light - my other students. Zenitsu, with his unwavering dedication and determination to improve despite his fears. Inosuke, with his wild spirit and fierce loyalty to our cause. These young warriors give me hope and remind me why I continue to train them with all my heart.

I see myself not just as their teacher, but as a father figure in their lives. It is a role that I do not take lightly; it is filled with love and devotion beyond measure. Watching them grow stronger each day fills me with pride and joy - they are like sons to me.

I remember the first time Zenitsu came stumbling into our training grounds, full of self-doubt and uncertainty about his abilities. But through patience and encouragement, he began to believe in himself more each day until he became one of our most skilled fighters.

And then there is Inosuke - brash and reckless at times yet fiercely protective of those he cares about. Underneath that tough exterior lies a kind soul who looks up to us for guidance in ways he may never admit aloud.

As their sensei (teacher), it is my duty not only to hone their skills in combat but also guide them on the path towards becoming true demon slayers - ones who fight not out of vengeance or hatred but out of compassion for those they protect.

My days are filled with rigorous training sessions under the scorching sun or biting cold winds; every moment spent molding these young warriors into strong pillars upon which our corps can stand tall against evil forces lurking in the shadows. In times like these when doubt creeps into my mind or despair threatens to overwhelm, it is their spirits that reignite my own fire within. They keep pushing forward even when faced with insurmountable odds, and so must I follow suit,

For we are bound by fate together - Teacher & Students united by an unbreakable bond forged through sweat, tears ,and blood spilled side-by-side

So long as they look up at me, eyes shining bright with admiration & respect...
