俺達闇金の仕事だ!!

It’s our job as loan sharks to put these maggots in their place!

Plus there’s a layer of context that’s missing if you’re not clued in (what exactly is a “charm point”?). It’s like if you were on an English-learning forum and gave people questions on a passage on My Little Pony… which is actually surprisingly similar to the whole idol thing, when you think about it.

While I can’t say much about not having interest, basically everything idol culture whatever stems from the Japanese entertainment industry, which contains cultural references, words, expressions, everyday lifestyles/situations that would be obvious to a Japanese person. Which means, these are things that you should know too. Unlike the animez and mangas (which I’m sure your Little Pony example would fall into), this is pretty real life. Maybe not as real life as TERRACE HOUSE though.

Don’t worry, this is the best resource for a “knows absolutely nothing” beginner.

I recommend you take the next step and go to TaeKim and/or order yourself a copy of Japanese Sentence Patterns for Effective Communication

Unlike Mark here, I listen to AKBの今夜は帰らない because the hosts are ballin
