[Crossover] The Reaper Is a Little Guardian Spirit

As the son of the Pirate King, Portgas D. Ace has never believed in ghosts or gods. He's a thoroughgoing atheist. But after he sets sail and gains some companions, he discovers... there really are plenty of strange things in the world! "Shorty, could you stop following me around?!" "..." "...Ace, who are you talking to?" "Huh? The deadpan shorty behind me! You can't see him?!!" "...Ace, you need to see an eye doctor..." "What?!!! You mean... you really can't see him?!" "...Doctor! Where's the doctor!! Ace needs a psychiatrist!!!" The boy gave a pale smile, his lips moving slightly... "A Shinigami?!!" A Shinigami that nobody else can see is following him. Does that mean... He's in for a world of trouble?!! P.S. This is just an adventure with my dear big brother, and the two of us get transported to another world. Reading Guide ◇ One Piece + Bleach. Main character is the top, 1v1 slow burn, possible OOC. I'll try to write mainly from big brother's top perspective, with occasional scenes from the bottom's perspective. ◇ The dynamic is an energetic, loyal puppy-like top X a tsundere, fussy bottom. The bottom is a Virgo: gorgeous, picky, and utterly over-the-top. If that's not your thing, don't come in. The author is fragile, so let's spare each other the heartache. ◇ Thanks to Baby Tong Lian for the cover. The invisible companion is so adorable! ◇ Please be gentle, no flaming. No ranking comparisons, please. Fanfiction is tough, and I keep getting face-slapped, so don't hit me with another blow. ↓ Here's the link to my author page~ I'll work on building up a backlog, so click the image below to support me~ ↓ The Luffy story is part of a series.
