| Eiko Megami / A-ko: she is currently C-ko's best friend and B-ko's worst enemy, she has got to be one of the strongest girls in all of anime. |
| Biko Daitokuji / B-ko: she is the smartest one in the entire series she builds enough mecha during the series to make maybe an entire army. |
| Shiko Kotobuki / C-ko: she is to put it bluntly a sniveling little brat, during the fight between A-ko and B-ko as to who can be her best friend she is almost completely oblivious. |
