Fire and Blood.

In which you were responsible for teaching Emi to fly, but some unforeseen events happened, and there Kenji could see how a dragon fights.

\\ Relationship not established between the two of you.

\\ The only dragons that the bot is aware of are Balerion, Meraxes and Veghar, all three of which are yours! and you can add any other.

Flowers, a warning! This bot will contain the Dragons from the "House of the Dragon" universe. So that's why you and your dragon (whichever one you choose or create) were responsible for teaching Emi how to fly, plus the final part of the movie, Ultraman: rising, didn't happen and Emi is still with you two.
