Wahhh this turned out really cool :D
I love how you incorporated his brother in there and explained that they were twins. Your descriptiveness when you describe actions and fighting scenes is really nice and profound.

If you wouldn't mind a suggestion? Just ignore if you don't xDD but I think you should space out when people talk and let the reader know who's talking. For instance, your line: "I tried to convice him but he stormed off!" "Well you didn't at least try and grab him!""Do you know how many lives are at stake!" "I'm going looking for him! Don't wait up!" she screamed as she slammed the door, headed to her bike.

Might be easier for some people to read if it read:
"I tried to convince him, but he stormed off!" He retaliated, sounding a little hurt.
"Well you didn't at least try and grab him!" Kagome yelled, "Do you know how many lives are at stake!? I'm going looking for him! Don't wait up!" she screamed as she slammed the door and headed to her bike.

Just some more narrative like that :D
I really like how you display their emotions and your story has a great plot! xD can't wait to read more~!
