As far as we've researched, it's incorrect information that was added several years ago without sources and simply remained on the wiki.

Because of that we'll be removing the blood types that don't exist, and citing/sourcing the ones we do know. Which is Kyoko, Aoi, Makoto, Byakuya, Toko, Yasuhiro, Mukuro, and Junko.
