This CM has been floating around since a couple of days ago… But in case there’s anyone unaware, here are the 2 versions of the CM.
Two things to pay attention to in the CM. Mizuki Nana fans will probably immediately take note of the BGM — which is among Nana’s latest (upcoming) songs — Jikuu Sapphire (literally translates to Time-space Sapphire).
The second thing to note is the seiyuu involved. As Nana wrote on her blog (and written in the title of this post), Sugita and Nana play the roles of Taiyou and Megumi respectively. I’ll be honest, despite the concept of the whole plot & twitter idea being very interesting and creative, I wouldn’t have cared about this CM if not for Nana and Sugita. XDD So good for them to get these 2 involved. XD
