Inside the basement of the mansion, Kazuya was given…

"Have you finished for the day, Nell-san?" Levin greeted her after she got out of one of the numerous devices that filled the area.

"Ugh… I still can't get used to this feeling…" she tried getting a feel of her own body.

"I know how you feel. While it may sound absurd when we heard about it, the amount of time we spend inside the machine learning with Rucy is indeed a lot more compared to the actual time that passes outside of it." Levin sympathized.

"That strange feeling is caused by the mental fatigue you are experiencing." A small holographic figure appeared between the two of them.

"Nell-san should be one of the toughest amongst us but how come she seems more worn out than us?" Levin curiously asked.

"It's because the time she spends inside there is double compared to most of you." Rucy answered nonchalantly.

"Huh?! Why?" Levin didn't expect such an answer.
