I like this but hate how useless the brother is, his only usefulness is what's described as well as a tamer and "MP Resupplier" as he call himself.
Like I said before, I like this but I wish the author should've at least made him less of a "House-Husband" type, but still let him be a tamer... Oh well, it's already too late anyway.
Edit: I take back what I said.
