EDIT: I read about 1 or 2 volumes when I originally made this review and now I've completed reading the whole series. One of the best action manga I've read in awhile. Extremely recommend. All the things in the old review still stand. Probably rating this way too high (in other people's eyes) but I'm pretty specific with what I like. I barely give any manga a solid 10/10 unless they somehow manage to amaze me to hell and back (not including this one, I gave 8 manga a 10/10.) I am a sucker for action like this. I'm sure there's many many things out there thatfollow a similar plot of "adult and child hitmen" or something along the lines but this was really good, even if it is possibly unoriginal.

It IS unfinished and I've only read the first volume in its entirety but even then, this still is a great manga series and I highly recommend it. The characters are awesome and I love the little girl, "Miharu". Probably a terrible comparison but she's pretty much Spike Spiegel here......or something along the lines, as said, probably terrible comparison.

Anyway, as of what I've read, this is a really easy 10/10. So far in vol. 2, my opinion's not changing. Sucks this is so underrated.

Also, I really really hope this doesn't get an anime adaptation. Please don't ruin it, big studios.
