A cute one-shot that just fills you with good feelings. That's it, really, but read on if you want to see just why.
Story (7) - The main two, Shiro and Kojiro (along with his good friend Saburouta), go to a small town renown for its water-themed entertainment. They partake in it as part of a small vacation, and encounter a cranky old woman. They find out that she used to be a rather popular dancer, but has since fallen out of grace due to her old age. Despite a promise to see the two with a new 'dance' when they visit again, she passes away;
However, her task is accomplished with a contraption of sorts that continues her life's work.
This isn't much by itself, frankly, but framing this against the general melodrama of Adekan makes it a breeze of fresh air. No crazy plot-twists or wily antics from Anri: Just a fun getaway for both the cast and the reader.
Art (10) - Since this one-shot is in colour due to its presence in an artbook, what is already stunning artwork becomes amazing. Tsukiji's wispy art-style mixes well with the murky colouring used in this piece, further amplifying the 'surreal' atmosphere the title is known for.
Character (7) - Probably one of the 'weaker' elements of the one-shot, but considering its nature, this makes sense. It definitely feels a bit more 'down to earth' and simplified compared to what is seen in the main story. A lot more quips and practical jokes are present than what would be in the title (which is already a fairly-comedic affair).
Enjoyment/Overall (6/7) -Like I said at the beginning, this is just a cute one-shot that makes you feel good. Read it regardless of your familiarity with the source material; It's worth it.
