Quick question (sound file included)

Ok so I've listened to this a thousand times, but for the life of me I can't tell what they (Natsumi and Strike-Man) are arguing about back and forth at the end. Strike Man keeps shouting "SEIGI-DA!" but I can't for the life of me figure out what Natsumi is saying back to him. Any help with this would be awesome. Sounds like "KIKYOMERO" but then again, I haven't studied too much Japanese so I have a hard time pin-pointing words/syllables.

I've uploaded the full sound clip but what I'm referring to occurs within the last ten seconds or so :x But it's fun to listen to anyway!

Thanks!

Sounds like kikyou mono to me. 奇矯 + 者

Konnichiwa ImNotJapanese-san!

She said "Hikyou-mono" and means "coward".

NANGI

Ah, I was close. I was thinking it might be the "h" instead of the "k," but I wasn't too sure. They can sound really close sometimes.

Ahhhh awesome, thanks everyone!
