Goro and Andy, thank you for the chapters.
I'm a bit shocked to see it: Kaito is taking a step in the right direction, and working out. He just has to remember that Rome wasn't built in a day--this is actually something a lot of people who start training fail to understand, which leads to impatience that ultimately results in quitting.
He should also be doing his best for Sylphy. Imagine her cheering you on as you work out.
