This is not terminology for anime fans, but they do know what it is. Yes, パセラ[pasela] is a chain of karaoke. The reason why this is so popular among anime fans is, that it has far more songs than any other chains of karaoke since it equips all the types of karaoke such as Joysound, DAM, UGA, or U-kara. So I’m sure you can find any songs you want to sing no matter how minor it is. Also, what gets anime fans the most is its awesome video. Yes, some anime songs play with a certain video of the anime on the screen such as Evangelion, Gundam series, BLOOD＋, Saint Seiya, Cowboy Bebop, Idolmaster, and so on(I can’t even count!). The number of anime video allowed to show, is increasing more and more. I really want them to get a lisence to show Haruhi video because currently there’s no Haruhi songs with its anime video available. That’s a shame.(つД`) But I hope it will come to pass.
The sad thing is that those chains of the karaoke are in Tokyo only(of course there’s one in Akihabara)…so if you come to Tokyo, you should definitely give it a try.
