Full Summary
After Ainz Ooal Gown dismissed everyone to rest, Aura who was about to retire to a room notices Shalltear with her notebook filled with notes she made of Ainz. Though initially teasing Shalltear’s obsessive thoroughness, Aura offers to help Shalltear review the notes she made from watching Ainz.

Whilst going over Ainz’s words and actions, their discussion somehow leads both women fantasizing about being useful to Ainz.

For Shalltear she imagines a scenario of Albedo being overwhelmed by the enemy causing Ainz to call for Shalltear’s aid to defeat them instead. After subduing the enemy Shalltear’s longingly imagines Ainz praising her and derogatorily comparing how useless Albedo was in the situation. And when asked what king of reward Shalltear wanted the vampire would decline as there no need. This would amazed her master who then asked Shalltear to always remain by his side.

In Aura's imagination, she envisions defeating the enemy with her many pets, and also depicting Albedo of being useless due to arriving late when the enemy is already defeated. For her reward, Aura relies that she wanted to spend a day with Ainz. This request makes Albedo in her imagination feel jealous and also asked the same thing only to be refused by Ainz since Aura did her job perfectly. When asked if Aura also had any other wishes, Aura requests to be petted on the head which Ainz complies.

In the morning, Ainz finds the two women have stayed awake through the night. While the undead is curious as to what the two were discussing he decides not to pursue the issue as he felt it was inappropriate to ask about it due it being private.
