So, I have been a user here for quite a while, observing the changes that occurred over the time, helping whoever I can, and writing my independent opinion for polls. You know, "kimi no tame ni dekiru koto mitskeru no sa"*. but unfortunately, "itsu made mo nante nai nda"** - life has led me to a new chapter, in which I would not be able to be here. "Ashita ga kuru kara"***, and we should adapt ourselves. "Kujikecha dame da yo, jinsei to wa sou iu mono dakara"****. Will I ever be able to return? "dōse darenimo wakaranainda"*****. So yeah, it was pretty much impossible to miss the music references I made here by now. This is my parting gift - these songs not only match what I wanted to say, they are also some of my favourite anime songs. Every one of them inspired me in a different way, and is from other musical genre. Note that number 5 and number 2 contain heavy spoilers if you watch the video instead of still image. Number 3 is especially recommended, including it's long version. (This opening also got the title of the third best opening of the year by a Reddit contest involving thousands of voters and dozens of openings).
