Did You Know?


The word "sarazanmai" is a portmanteau of Japanese phrases:
  • "sara" means plate. In Japanese mythology, kappa (water demons) have a plate on their heads that contains water. Whenever a kappa is on dry land it must keep water in the plate; if it ever dries out the kappa will lose its power and eventually its life.
  • "zan" means "three" (in Japanese either "zan" or "san" is used for the number), referring to the three protagonists.
  • "mai" means "real love" ("ma" meaning "real" and "ai" meaning "love"), referring to the connection between souls.

I honestly thought I had high hopes for this anime, but it turned out disappointing instead as I went along......
3 May 2019 | by IrishchatterSee all my reviews

After watching 4 episodes of this anime, I found that it kept having the same format on each episodes. We are hearing the same two songs again from the characters, as much as they are catchy and good, you want others too! I'm not saying to keep producing new songs and then the rest is forgotten but I would like to have at least more new songs on the anime to add freshness to it. When I first looked at this anime, I was blown away and fell in love with it straight away! I also was surprised to find out director Kunihiko Ikuhara also directed "Revolutionary Girl Utena" which I loved and I was so disappointed I didn't like this one. This anime was so colourful, had great Japanese voice actors as well as involving their singing voices and the characters were good. Unfortunately I felt the storytelling was rather too vague by not thinking outside the box to add more new ways to attract viewers like myself to keep watching it.

I think its best to stop watching this anime and hopefully find other "over the top" ones that are way better then this!
