Architect, an F.A. Girl without a physical body, intrudes on Gourai and Jinrai's battle, attacking with clones and pre-programmed subroutines that adapt to the situation. After Gourai and Jinrai manage to win the battle, Architect experiences an error in her programming, which Gourai manages to fix with her act of friendship. Afterwards, Architect receives a physical body and is delivered to Ao's place. Later, as the cleaning robot is fixed and given the name Sleipni-taro, the F.A. Girls hold a race to buy some vinegar for Ao, with each team facing their own troubles except for Architect.
