Great story!

My fav character is Amano so I'm happy to see a good story with him as a main(?)character.

KEEP UP THE GOOD WORK!

Okay. First point: Your grammar is exceedingly bad. Almost as though everything in quotation marks is allowed to have no other punctuation in it.
Secondly, you characterize poorly. Not to mention you make Amano sound like a wimp. "aw aw aw!" Nothing like capitalization in this day and age.
Actually, let me re-phrase, you make everybody in this entire story sound like wimps.
You know, your writing isn't too bad, as long as you don't read into it. If you read into it, you come out again screaming.
