Shounen

An F-Class Hunter.
    And on top of that, a F-class older brother who can’t even begin to catch up to the heels of his amazing S-class little brother.
    After living a life that fell to pieces and even destroying my little brother’s life, I got another chance by regressing 5 years back. I picked up the resolution:
    This time, instead of making those mistakes, I will quietly live my life leisurely .
    Is what I thought… but the S-Ranks are all kind of… weird and for some reason I can’t seem to be able to get away at all?
