Comments of chapter undefined of Full Counter in Fairy Tail

I plan for the MC to have like two side of himself which you can sort of see in the first chapters I have written. They will be very conflicting in their views but similar in ways as well. Yes kill. And not lighthearted world view. Power of friendship may come into play down the line when the lighter side of his character develops away from his dark. I have not decided on the romance side of it kind of just seeing where it goes. I will have him join sometimes with the maincast for big canon adventures events but also want him to have his own adventures in places not visited in manga or anime if possible. Thank you for your questions!
