Outlines
by Ana_RinRay
"Where did it all go wrong? Did Ishida’s arrow miss its target? Or Zangetsu didn’t strike true?It doesn’t even matter now. The worlds are slowly, inevitably falling apart.Kurosaki Ichigo and Aizen Sousuke, the last living beings in the dying Universe, are spending their last moments in quiet conversation." This is a Bleach fan comic, an alternate TYBW ending time travel fix-it. Plot-heavy angst with a relatively happy ending and a lot of sad music.Can be read as platonic AiIchi.Will contain some loose lore interpretations and OOC. Ignores CFYOW.No NSFW, PG-13 for canon-typical violence&gore. Mind the tags! 1 page = 1 ao3 chapter; posting roughly 1 new page per 1-2 weeks. Note: starting Jul 2026 I will only be answering direct questions in the comments!Just know that I treasure and re-read each and every one of your beautiful comments, they give me strength to continue 💖💖💖

I Went Down, Down, Down (the Flames Went Higher)
by northpeach, wolfsrainrules
When Ichigo coughed, he felt the familiar taste of iron slip from his lips. He inwardly cursed, both at his injuries and at the weak voices he couldn't make out. He shouldn’t have let his guard down, just because Ginjo and Xcution was dealt with. The Dangai was always dangerous. He shouldn’t have forgotten that. A brush of reiatsu and something moved in his vision- gray and purple. Ichigo pried his eyes open, catching a glimpse of a familiar face.“Jii-san.”Yamamoto Genryuusai placed a gentle hand on his face and Ichigo leaned into it, allowing the darkness to overtake his vision.

Except, how did he end up obsessed instead? “Why did you reject the captaincy position that I recommended you for? Do you know how much paperwork I had to fill out?” “But Kurosaki-taichō, if I leave your side, I suspect I’ll die of loneliness.” … What the heck?

As Urahara said back at the beginning, a soul in danger of destruction will manifest powers more rapidly.

So are his friends. Urahara lies in a pool of his own blood, his corpse holding out the tool Ichigo needs to fix it all- the hogyoku.It allows him to travel back in time, to the moment he climbed out of the shattered shaft, ready to save Rukia from her execution.Now he has the chance to change the future. He could stop Aizen, keep the war from ever happening, never have to use the final Getsuga... so many possibilities. But first he needs to save Rukia, and figure out who assassinated everyone he loved in the future.

Trade All My Tomorrows
