This is a nice story line but the grammar issues make it difficult to read and enjoy. I’m guessing that English isn’t your first language. Translators don’t catch the correct placing of words and phrases. you should probably look into getting a beta reader to help you with that. Good Luck with your writing. I hope you keep writing. If you can, read other fanfics and see how some things are worded. That might help. 

Nice chapter. It is very interesting and would love to read more. I am no grammar expert or a writer or a beta but I think there are a few errors in the chapters but it does not take away from what your are conveying in this story. So far you are doing very well. 

If you want to you might want to find a beta to help you along. Is English your main language? The reason I ask is that for many cultures our language tend to be somewhat confusing so you can imagine how the grammar and sometimes the spelling of some words can be confusing, especially American English, to other people from other countries.

If Inuyasha was suppose to be watching out for Sesshomaru why did he let Kagome take him out of the barrier? Was he cursed or something like that? These and other questions have piqued my interest but I know you will answer these and other things will become clear as you continue your writing of this story.

Keep up the good work and I will be looking for future chapters as you get a chance to post them. Great writing!

A thrilling little tale. What year is this setting? Could the man in red be Inuyasha and the child with the furball be Sessho when he changes or something like that? This is interesting. Nicely written and would like to read more soon. Good job!
