Sumiko's Team

Sumiko Sumimura generally refused all job offers from The Shadow Organization, though for some reason agreed to take part in a single one involving a Shinyuuchi god that needed to be calmed. Instead, however, she killed the god and cut its child from its body, allowing the child to become the new master of the Shinyuuchi.

Combat Strength
Sumiko was originally intended only to seal off the area while her teammates calmed the god. This implies that they were considerably powerful as a unit, though Sumiko's individual strength clearly shocks them all.
