Your story is really amazing! Unlike other fanfics, your creation of Harry’s personality is unique. It also melts my heart deeply. I hope for the sequel of brutal Harry.
I love finding great writers, and while I wish you had more books, brutal harry is amazing! I wish you had more books because you are one of the best writers that I have seen! I hope to read more of your works in the future.
You are an awesome awesome awesome writer! I love your story! I don't know, but it encompassed all my favourite genres and defintely is the best HP fanfiction I've ever read. Totally worth the 7 hour read.
I think your story may come under the 'harem' category, though.
It's got Japanese swords, guns, armour, sci-fi and magic. All in a Hogwarts castle where Harry is one badass hero. Just.... whooo! I'm gonna die of joy.
