Is Raki's armor special or something? He was able to deflect the yomi's fingers from his face, whereas Riful pierces through Rune's armor.
Or is it just a technical aspect, as Raki's vambrace plates looked like they overlap one another when he deflected? Strangely enough, it's a standard vambrace when he stands still...
Then again, perhaps it's just that stronger beings have stronger appendages and Claymores deflect regular yomi as well?
Feel free to discuss or speculate anything else Raki may have gained the past 7 yrs. Hanging around with Isley sure did some good for his attitude.
Edit: Currently skipping around earlier chapters, during the fight in the Church, Galk's armor was penetrated as well. Dunno if human armor is different from Claymore armor.
