Okay. The ringo catalog parts: The first one with tsumiki asobi is at the section with mm after the first vocal part. The one with the guitar part is at the bit where ksk and some parts of ss are playing. And the ichijiku no hana part is at the complete end of the song. Playing it backwards makes the inh part first.
The XXX honnou thing is when you do something to the song and some notes show as xxx around the part with the xxx action in the video.
Is that better?
