The first 11 seconds come from Rideback, an anime premiering on January 11. This preview is unmistakably MELL, even without the credit at the bottom. Is it I’ve? Who cares? More MELL is always a good thing. It sounds a little bit bright for what we expect from her, but then again, we’ve only heard 11 seconds.
The other twenty seconds come courtesy of Web Giga and the preview to their Comiket offering, the theme song single to BALDRSKY, “Restoration ～沈黙の空～.” Since the file might be hard to locate, here’s a direct link. Restoration, as opposed to the unnamed MELL preview, is exactly what we expected, with hints from C.G Mix of Face of Fact and his Prism Ark themes.
