I have to admit I'm not a fan of anime. Or at least I tried to in order to fit in a little more with my age group. About 5 years ago I remember having my first go at this brand of cartoons with ninja 'Naruto' and alien frog invaders 'Keroro Gunso' (ケロロ軍曹), but I eventually gave up as I found that the story lines became more and more twisted, difficult to comprehend and just plain weird as it progressed.
Then came The Law of Ueki (うえきの法則). Like Keroro, I was introduced to it via this manga comic book by the name of CO-CO/COCO... the much slimmer Singapore version of it unlike the ones they have in Japan. Man, those there are as thick as phone books! But anyway, having discovered that there was an anime - or to me back then, it was just known as a cartoon - based on this manga by Tsubasa Fukuchi (福地翼), I decided, "Hey, why not? The comic (manga) seemed pretty interesting anyway!" And so I did watch it. 51 episodes long with a plot heavily emphasizing on justice/righteousness, it wasn't too bad... I liked it.
Hitomi Shimtani's (島谷ひとみ) 19th single 'Falco - ファルコ -' served as the series' theme song for the first 32 episodes, and it also caught my attention with its use of instruments like the sitar and its exotic, middle-eastern/Indian arrangement. An intriguing song to say the least and it at its chorus it sounds like your typical catchy anime song... or anisong, as I think they are known as. And I would say that it was one of the more memorable theme songs I had heard then. Another one being the 5th theme song for 'Keroro' 'You-You-You' by the rock band Polysics... although I never actually made it that far into the series.
Just a about a week ago I revisited this relatively old anime (aired in 2005 and ended in 2006) and listening to 'Falco' again just brought back all those cherished memories from the last year of primary/elementary school... back in the good old days. Hmm, I wonder if my friend watched it. I knew he watched 'Keroro' but I'm not sure about 'Ueki', never did ask.
For the song's stats, it was released on 10th August 2005 and peaked at 11th place on the Oricon weeklies, eventually settling at 265th place by the end of the year. It was written by this songwriting duo BOUNCEBACK (yes, in all caps) and was composed by Kazunori Watanabe (渡辺和紀). The video below shows the anime's opening sequence, by the way.
