Some of the major events happened in manga may be reversed in this fanfic book. And also, some spoilers from the manga may appear in here as well. Kocho Shinobu really loves to tease Giyu Tomioka even she really hates him due to his personality and lack of communication skills towards others. But how she would react that behind that cold personality of Giyu, he has that kind of personality that she wouldn't have expected.

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? -Certain character ages may be changed for the sake of the story (specific birthdays will be explained later). -Manga spoilers (why would anyone read a fanfic about the end of the series if they didn't finish the story)
