Choji and Choza in “Unfinished Business”

Choji

I thought it was just an oath, part of a ritual. Now I hereby swear as the 16th leader of the clan, I will pass on this oath entrusted to me by the 15th, and I shall carry it onto the 17th leader, my child to be. [flashback ends] Thank you Ino, and I'm sorry, but I'm okay now. You can go back. In order to protect the Yamanaka and Nara clans and the Hidden Leaf Village, I, Choji Akimichi swear to transform from a lowly caterpillar to a powerful butterfly and take flight!

Choji!

Choji

It's time to change.

He grew wings without even using the pills!
