After the day of school ended, Michaelus and Rias were heading back to the Ark, they witnessed two exorcists tied up by Bulkhead.

Their names were Xenovia Quarta and Irina Shido.

Xenovia: Hey! Let us go, Devils!

Ratchet: For the last time, for Primus' sake! We are Autobots! We are not from this planet!

Xenovia: YOU LIE!

Michaelus: MATRIX OF GENERALSHIP! I CALL UPON YOU!

The matrix glowed and Xenovia was shocked at the sight of the light of a Prime.

After the history...

Xenovia woke up and realized that what the Autobots were saying was true.

Xenovia: I-I'm sorry. I didn't realize how your people were robots. The church told me that you were all devils. I'm such a fool!*starts crying in regret*

Optimus: You were deceived by the church. The best way to learn about our race is from Michaelus.

Arcee: Michaelus becomes her teacher?

Ratchet: Oh Please! Isn't having teachers next to our base enough?

Everyone looked at him with an 'Are you kidding me' look.

Ratchet: What?

Michaelus Prime: Gramps, you really need to calm down. The way she needs to learn how the church has lied to them is by rebelling it.

Rias: He's right. As of right now, we must be ready.

Michaelus: Is Any Fallen Angel a Leader Class?

Xenovia: Yes! It's Kokabiel!

Fallen Angel Headquarters...

A Leader Class Fallen Angel named Kokabiel has been preparing for a new war. A war that will end both Autobots and Decepticons.

Kokabiel: At last, Earth will be mine to conquer as well as Cybertron.
