The conclusion to Banner II: Lafiel crying when she reunites with Jinto after he survived three weeks on a prison planet. She even sheds Tears of Joy, despite the fact that "Abriels don't cry". Jinto dries her tears despite his starvation weakness and reminds her of this while calling her "my precious princess". What happens next? Tears and her affectionately calling him an idiot. What comes after this is also heartwarming. Lafiel leaving the Star Forces in order to accompany Jinto to his recently reconquered home world. She says it's only temporary and it wouldn't affect her career and asks him (again) if he wants her to come in a manner that doesn't accept "no" as a answer. He responds that he wants her to stay with him.
