Lovely performance, but did she make a mistake or was it the lyrics? Around 4:19, the lyrics were jishin motte, yume wo motte, tobi tatsu kara. She said jishin motte, akiramenaide, kageyake mirai.
It's the first time I get to hear it fully and properly too, I like it!
Edit:
I see it has been picked up by someone else, aichan :3 I wish she'll have a solo career too, where she still sings.
It seems like they're treating her really well. You don't reckon her going on her own on a show and singing her song, is an indication of what's to come? And the fact that they have a solo calender for her...We might have a good singing career out of her and not having her fade in the dark. I really hope that's the case.
