In 2021, an overworked and tired 26 year-old woman named Reiko Ikeda cares for her comatose brother who was injured in a gang fight. Reiko blames herself as she had abandoned her younger brother when her parents divorced, leaving her brother to eventually fend for himself and become involved in gangs. Thus, she has spent the last eight years waiting for him to awaken to make up for her selfish youth, but learning that all she has worked hard for may never come to fruition, Reiko feels hopeless and contemplates suicide. However, somehow, she dies while saving a little girl's life and returns to 2011, the day when her parents divorce. This is her chance at a redo, a chance to live her life as she has always wanted, and a chance to save her brother's life!

In her quest to change her brother's fate, Reiko must get involved in the gangs of her hometown that run deeper than she imagined.

Author's Note: At an anime con, I saw so many people wear the Tokyo Revengers Outfit even though I didn't know where it was from, and I thought it looked cool! So I watched the anime with my S/O and got an idea in my head, so here's the result of imagining a new story inspired by Tokyo Revengers! (Also I very much dislike the Tokyo Revengers MC, so... this was also an emotional outlet from the frustration he gave me lol.)
