Ok, finished watching HPH #7!
Risa's Koi no Hana was pretty good! I don't actually like the harmony clutter in the original version, so it was nice to hear the song with just one vocal melody. I was somewhat disappointed with Risa's performance otherwise though, it seemed like she was in her own world instead of performing the song to others. Either way, she was pretty and stuff.
Once again the talk with Risa and Eri included some video footage which I dislike. So let's skip to Kanna. Her replies mostly consisted of "hai" and "aaa~" so she seemed a bit nervous, but she was so cute! It was funny she accidentally called Risa "Niigaki-chan", although I think it was honestly more a tongue slip than a mind slip.

She seemed to loosen up towards the end too, so I guess Risa has the ability to make the other person relax in an interview. I also think Kanna's reactions to Niigaki were funny at times.
Kanna's version of I WISH was vocally pretty bad, her voice is kinda whiny and not that strong. However, there was obvious change in her voice and the mood of the song when the chorus started and for some reason her performance was pleasant to watch. She was actually performing instead of just standing on stage. Loved the smile on her face. I felt the performance was more than just a karaoke version of a MM song, even if the vocals weren't that good. So Kanna continues to be one of my favourite kids.
Now, I found the talk with Risa and Eri surprisingly boring, heh. So I haven't really got a lot to say about that. Eri's version of 100kai no kiss was pretty lovely, however. I love the little vibrato thing she has going on. I kinda hoped for a bit more strength in some parts though (her voice sounded so 'breathy' at times), but the wow-wows made up for that a bit. In any case I like Eri's voice a lot.
In sum, this HPH was very nice. The talks were a bit more boring than I expected, but the perfs were quite special and cool.
