RE: RE
This little gem of Animation, known colloquially as "Erased" (although its full title could be translated as "The Town where I'm not") was one of the Animes that I liked the most from last year. The boyfriend was the one who recommended it, so we saw him in several sessions, somewhat surprised by the multiple twists in the plot.
The premise presents a somewhat mediocre young man with a unique gift: he can go back in time to avoid small tragedies or accidents. However, one day a great tragedy happens that affects his quiet life, destroying it completely and when trying to fix the situation, he travels to the past a multitude of years ... returning to be a child. In this time he discovers that changing his future tragedy could be prevented by just saving a little girl from his own tragedy ... However, changing the past can generate a storm of differences in his future (when the OP changes animation to reflect this, it is shocking).
The song of OP has the same rhythm that many others of Asian Kung-fu Generation, with a vivacious and adventurous tune. The lyrics, on the other hand, talk about regrets, wanting to change the past and not being able to return to it, which fits very well with the plot. The title of the song seems like a repetition (loop of backs to the past: D).
I recommend this short anime, which makes us think about how everything we do can have an impact on our future ... and that it leaves us with the teaching that sometimes saving others can save ourselves.
