2nd Chances

Giyuu lay dying on his 25th birthday recounting all the good times he spent with his friends before and after the final battle with the demon king and his servants.

Yet, as he takes his last breaths and finally finds solace in the life he's lived, he is mysteriously transported back a whole 8 years in the past.

Now faced with a second opportunity to correct his mistakes and save the lives of those he felt indebted to, what would he do?
