Nice mate...very nice. You know I am enjoying your story immensely, from the dialogue peppered with humour and intensity too the developing characters that I am enjoying learning about. To the unique notion of your storyline, articulated very well. But I do have a few suggestions...
-When you have introduced a character and established a definitive relationship between them and the reader. You no longer need to refer to them by their names. It is usually more grammatically fluent, and easier for the reader, if you refer to them as in Kazuki's case, "Him" or the "the pupil" or "gifted martial artist" or something else of that nature...
-It gives your story more substance if you add a bit more description i.e. what does the suit look like? The machine? Hiroshi? It will help the reader to engage into your story and such...

That's about all. I'm really enjoying this story mate, I can't wait for the next chapter! I especially commend you for your sue of dialogue, I'm completely inept when it comes to dialogue...lol. So kudos to you...it's witty and enjoyable...
