Well, here another karaoke video, i tried to equalize the audio so you can hear Lulu on the right and sephira on the left, i'm not sure if it's well renderized (to lazy to test) XD this took more hours than i thought inicially, but well i love Lulu and Sephira so i have to make this :D hope you enjoy it and if you can share the video 
As always, the karaoke will be in hard subs and the translations for english and spanish will be on cc :D
