Tusk is frustrated because he didn’t get any. Stupid lizard priestesses interrupting them.

They are captured, and somehow Tusk ends up in this position.
The princess who piloted the mecha before saves them from being executed.

In returned, Ange tries to take her hostage.

Her friends take Tusk hostage in return, but Ange doesn’t mind if they kill him.
The princess tells Ange the truth of the world. Ange came from a false world created by Embryo, who is really evil and stuff. The norma actually powered mana by killing dragons.

The princess asks Ange to stop killing her people.

Ange refuses to stop killing her people and picks a fight.

She gets the crap beat out of her. (Also, she deserved it.) Not sure how the lizard princess managed to put her in this position but whatever!

When Ange wakes up, Tusk is teaching all the lizard girls about sex.

Ange joins in on the fun.

…
This show is kind of getting too normal, with an ordinary plot. Could have been the new Gundam series. Or more like Tales of Symphonia lately. But it still has some terribleness like Tusks’s sex education which makes it amusing to watch.
I also enjoy how consistent Ange’s characterization is. No matter the situation, she makes the bitchiest move possible.
I know this was way after the end, and you’re kind of being facetious here, but the scuffle, which was handled a little haphazardly (Ange had just been HORRIFIED when she found she had been killing sentient beings, and had been forced to as part of living on Arzenal), was over the siege in episode 11, and IIRC the fact that Riza had been spying for them. Sala also had a one-sided advantage in that fight being able to fly.
