This is Shinji Ikari from Evangelion. He says “Iya, ano“ as long as the button is pressed, then “boku wa betsu ni!“ when the button is released.
This is from the scene when he walks in on Misato Katsuragi in the shower and is apologetically stammering.
This is a “Sound Drop“, a Japanese toy that comes inside toy capsules called Gashapon. It plays music or voices from
popular anime series when the big button on the front is pressed! They are official, licensed toys from Bandai.
There are a lot of different types of sound drops from various anime including Evangelion, Naruto, One Piece, Dragonball, etc.
I carry a ton of sound drops on my eBay a look if you’re interested!
