Asterisk is a great song, and the visuals on that opening were great, too. Opening 15 definitely carries a lot of nostalgia, with bits of the intro throwing back to the first opening. And yeah, Harukaze is one of my favorite opening tracks. Ranbu no Melody is good, but I feel it's the top-notch visuals of that intro which drive the song into near-and-dear territory.
In my case the funny is that when I watched Bleach I just hated to watch the openings(and endings).I didn't watched any of them and I didn't care about the music.It was just losing time for me.Until Shojo S(10th).One day I decided to watch the opening and I just loved it.Then I liked Anima Rossa(11th) and ChAngE(12th).
After I finish the anime one day I saw a gif of 13th opening(Ranbu No Melody)and I decided to watch it...now I know the lyrics by heart
And it's same with ChAngE and Shojo S and Velonica.I listen them and sing them all the time.And actually i think I like all of them.I just don't know why I hated the openings in the beginning
