To me the Cloche-sama in Japanese characters is far more baffling than the Raki bug...I mean, I can see how the Raki bug could have been missed. Heck, I missed it myself the first time I fought her...it's really not hard to beat her in time. But though the effect is much more minor, I just can't see how the Cloche-sama thing could have been missed. It only comes up every single time you save an I.P.D., and there's what, 100 of them?
But yeah, it seems like NISA has been doing much better lately. Heck, even Last Rebellion has a pretty good localization from what I've heard, though I do have to question their priorities as to why they would spend the time to make a good localization of what is such a bad game.
