In NAC's secret arcade mode there is a weird mid boss. From what i have gathered the Damiens armies Neco arc chaos's are just a ton of coppies from NAC using 22B and C that just wondered off after every time the attack was used. During the dialoge the other NAC clearly said "(Two arrows down) B or C".
I think this is pretty funny. Any body who can read the kanji let me know what it is generally saying.
