Ichigo has come with all the female Shinigami to the beach after their Soul Society pool got destroyed by Byakuya. Renji and some of the other guys have come along too, as have Inoue, Sado, and Ishida. With everyone gathered, Ukitake announces a seaside art contest with a cash prize, and several of the Shinigami are enticed enough to participate, including Rukia and Byakuya. It’s Kiyone and Sentarou who inadvertently end up building a sand coffin around a sleeping Ukitake that judge Unohana thinks are the winners though. All of this is interrupted when a monster suddenly attacks and captures Nanao and Isane. Unohana isn’t surprised because she had heard of a strong Hollow here, they have a hard time fighting it because it can absorb spirit attacks. A second one then appears, but fortunately Yoruichi and Soifon show up and are able to use direct attacks to take both down. Afterward, Ukitake wakes back up and, with the other captains who knew about this, explains that this was actually all part of the watermelon splitting activity. These particular watermelon monsters were created by the Research and Development Institute to fight Hollows, and Ichigo and company have several more to take out.
As a fun fanservice episode, I think this worked quite well. Even though I was familiar with the omake chapter from volume 29 of the manga, I found the Ukitake coffin joke to be hilarious and really couldn’t stop laughing at how they did it here. Hitsugaya serving as basically an ice machine was pretty amusing too. And as expected, there was plenty of cleavage and revealing swimsuits, and they even kept in the breast buckets joke and added tentacle monsters. So I really don’t have much to complain about this, and I suspect that a fun episode like this will look really good when we’re deep in the anime original stuff that’s coming soon.
Speaking of coming soon, it looks like next week will be another one-shot about Keigo’s sister Mizuho (we already had one back in episode 133), and the new ED should start the week after that, probably along with the new anime original arc.
