Yeah for Pikari! <3 I don't mind the translation, 'What do I have to do?' To me, it completely implies that Kurogane isn't even bothering to ask what the price is- the idea of NOT paying the price doesn't even cross his mind. And when Kamui refuses to let Subaru give his blood, the translation, 'If he becomes an interference like that hunter,' makes a lot more since than, 'if that hunter becomes a hindrance again,' since Seishirou isn't there. XD
...I'm still loving the idea of Syaoran and the X characters standing there thinking, '...Yep, they're gay.'
