[@Akashi Mayhiro] 
I will respond to your various reviews/questions in the same order presented, I just don't feel like going through the hassle of quoting so I figured I would explain. Also thank you for reviewing so quickly. 

At the moment he does not have any other relatives to speak of, though while writing him I was developing a backstory for his family. So there is a distinct possibility that other family members could show up, it would not be a warm greeting however. 

If I understood your wording correctly you are saying that if an enemy gets in close combat with Daisuke they are done for? If so that is relatively correct, though of course it depends on the skill of the opponent and the number of them. 

Accounting for his affinity for Doton, his stamina/chakra reserves, and his still below average chakra control I would guess that he could maintain the C rank jutsu for an extended period of time, I do not know exact numbers off of the top of my head, B for just above average for that Jutsu, and A rank would be right around average with the possibility of being a bit under depending of course on how large/deep he makes it.

I placed Hammer as a B rank simply because that is what Savato suggested. Depending on what Partisian says I will change it accordingly. 

Once more thank you for reviewing my character.
