This takes place in Neo-Inazuma
The team's base is located there, damaged from L-1's attack and the other Zandicorp robots. It was a mess, but Yae Miko was helping since it was also her base.
Kaveh was still angry with Raiden and Nomad (RS-02), aka Scaramouche, since they ruined his "babies"—Raiden ship and Nomad(Scaramouche)robot—but he was fixing them. His anger would soon subside.
Mona, also RS-03, aka Raiden's creation, also called Raiden but known as Ei, was recovering in the infirmary. Mona, being human, was being treated with human supplies, while Ei was being repaired like the other robots.
Albedo (L-3) was also resting, since it took a toll on him when L-1 controlled him.
Sangonomiya too she was helping the others clean up the place.
Nomad (Scaramouche/RS-02) was in charge of stabilizing the systems, which had been hacked. While he was doing this, Raiden approached from behind.
Nomad was his son, and Ei (RS-03) was basically Nomad's older sister.
