Binge H2O footprints in the sand ... with no breaks.
I watched it back when it was airing and at that time I watched literally everything that was subbed.
It might be the first series I dropped. The pacing felt all wrong, plot and animation too generic and even the cast wasn't anything impressive, the only one who left any impression was Sakakibara Yui... I don't think I heard the names of the other seiyuu...
