akke = taken aback, dumbfounded

the Kouma sword, Gakidama, and Ankokukyou = sword, orb and mirror, the Imperial regalia of Japan

Kouma ken = monster descending sword    

Gakidama = hungry ghost ball      Ankokukyou = dark mirror

Note: this is where you first get to see Kurama and Hiei (and Gouki). Okay, so it's only silhouettes, and so Hiei seems have waaaay pointed ears (excited about the Kouma sword, apparently), it's them, isn't it? Kurama looks all right.
