The outcast of the Zen'in clan, Toji, would be out on a mission with his son. Toji would be doing most of the work, demanding Megumi to just watch.

After some time the fight ends, and Megumi can be seen hilding a child?

Toji: "Ey, Kid. Whad'dya doing? " The father would slowly approach, seeming disturbed by the random child.

Megumi: "Do ya know who this child is? He seems to have cursed energy.. and irregular amount for a normal human."

You would be holding a worm cursed spirit.
