Tanjirou finished another grueling training session.
With brush in hand, he proceeded to write another journal entry despite the pain in his wrist after swinging a sword a thousand times.
He was determined to learn all he can to be a Demon Slayer.
There were times he doubted himself, yet he didn't give up. He can't, he won't.
The sleeping girl lying on the floor was the reason why.
Setting his brush down, Tanjirou gently ran his palm over the girl's forehead. "I'll keep working hard, Nezuko."
He was determined to save his sister.
And so, he endured another day.
