And it translated so well int animation, plus you gotta love Miki just continuing even while Chihaya is trying to stifle her laughter and Haruka is dealing with getting booped.
The funny thing is this is actually happened to the seiyuu of Haruka (Nakamura Eriko) and Chihaya (Imai Asami) in their radio show. So this segment was a genius xD Oh and Imai Asami is also the voice of Kurisu -tina- and Noire
Please vote for the funniest part of this segment. a. Haruka getting hit in the face by the box lid b. Chihaya desperately trying not to laugh c. Miki just not caring d. All of the above
Apparently this actually happened to the Harukas Seiyuu. It was her birthday and Chihaya's seiyuu was also there when she got hit trying to open the box.
In fact, this scene was come from the real life in a radio broadcast which the voice actors of Haruka (red) and Chihaya (blue) hosted. See 【比較】アイマスとゆうパック
Hilarious. Also, noticeably if you slow down the animation, the box immediately flies open and upright instead of gradually doing it frame by frame. Wow. Who cares. It's a hilarious scene :)
Moe! And Kisaragi, hilarious! her curiosity... Gotta hate the moments you try desesperately not to laugh, when you shouldn't. How embarassing! And Miki, how can she keep it all that natural?! "this ice-cream is kinda weird" xD
