About that guy in the gifs... I think it's just a preview of another PV, because 「Microphone」box fades away on that moment
Maybe off topic, but I found this on
Avex Avexnews on facebook (it's linked with
their twitter):
浜崎あゆみ 3/19(金) 日本テレビ 25:00～25:55 音楽戦士 MUSIC FIGHTER 番組開始から５年半、これまで出演してくれたアーティストとのスタジオトークを振り返る超豪華 総集編！！
This is what I get from the online translation:
