Fami Can Also Replicate Devil Powers & Contracts And Give it To Other People. This is where Fake Chainsaw Man and The New Girl Come in (Theory)

Fujimoto Is Trying to Trick Us Into Thinking Fami No Longer Has any roles to play, but she orchestrated everything in the beginning of Part 2.

With her ability she gave the chainsaw man abilty to someone in her church and she gave the contract Kobeni Had to the new girl.

The rings in her eyes could be the result of getting the power from Famil.

Fake Chainsaw Man and her are going to play the final role against the Death Devil.

That's why Fami Can Now Relax and enjoy the festival while she leaves it up to them
