Charm

How is this unknown group connected to Wingless Crow?

Souta on their way to the Wingless Crow base asked the leader various questions. He learned that the Wingless Crow wanted to take over the Mine Valley but they were too weak. So they just hid in the dark manipulating the event before they take a move.

Their plan was perfect. Various powers would fight for the three cities and once they exhausted their strength the Wingless Crow would appear to dominate the Mine Valley. Unfortunately, Souta discovered them before they completed their plan.

They even bribed some City Lords to join their forces. The three City Lords that attacked Bland City and the City Lord of White Line City were all bribed by them.

"Are you working for some people?" Souta asked.

"No," The leader answered decisively.

"Then, why do you want to occupy the Mine Valley?" He asked another question.
