Actually that isn't even my favourite genre XD But in Japan, every season there are at least 2 or 3 detective dramas, so...

But we're gonna watch almost the same dramas!
(I've just seen that there's already the raw of the firs ep od Swith Girl. Didn't remember it started the other day O_O)

Mmmh, yes, I think? Scrap Teacher was aired douring... 2008, maybe? I'm pretty sure it was before Hidarime Tantei. And in that period his voice was definitely not low XD
