Kaji finds himself wanting to become a gambler who not only gambles, but knows what it takes to win. As a first step towards that, he recklessly confronts the Nitro loan sharks without Baku's help. He is luckily saved by Baku by the end of the chapter through a lottery ticket bluff.
This shows how much Kaji wants to change his own life and become someone like Baku, to the point of confronting danger without seeking help from Baku first.
