Haha, I've just watched it. Lolarious. It's a dream remake of the Soul Society arc and gave me all sorts of mushy nostalgic feelings. Also ... the ending was clever as hell.
That firebird really pecked the hell out of RukiRuki's forehead! ROTFLMAO.
I loved all the Ishida-ness and the naked Chad, of course--especially, omg, the sexy way CHAD RUBBED THE KON LAMP JUST BEFORE RENJI APPEARED... did anyone else find that unusually hawt? Ha.
I'm on cold meds at the moment so when Seaweed Ambassador appeared I think I had flashbacks to other peoples' parents Woodstock euphorias. (I'm not that old!)
eta: Ah ha, Sensei is tweeting about how he liked Rukia's costume in the episode--and Urahara's hat! Ah, I love this episode! The animation isn't great, but the concept beats everything and the IshiHime shipper in me just noticed on the third watch that Urio and OrI Mei call one another by their first names and that Ori Mei calls Chigo "Chigo-kun" ROTFLMAO. Oh there are some really cute gifs by Maskonna from BA here. Please pause the vid in the Urahara's treasure room--HAHAHA, there are some interesting treasures there!
eta2: BWAHAHAHAHAHA, Sensei not responsible for Renji costume travesty! Nacchan translation: "living world members+Yoruichi's outfits were based on my spread, I get to check others too except for Renji's modification" 現世組＋夜一は、俺が描いたポスターの衣装を着てるから、デザインっちゃーデザイン。そ
