"Where is Nathan?" Sera asked while looking around.
Selena glanced at her mysteriously, as though something bothered her mind. Ultimately, she said, "He is in the bedroom, absorbing some cores. Unlike us, he needs more cores to have the same amount of Ena as us.
"That's why this trip is for him to have the time to swallow those cores.
"It's quite stressful mentally and physically, so absorbing it here will help a bit. The school is pretty chaotic after all."
"Fair enough." Sera looked surprised that Selena gave all that information. She soon smiled and gently pushed Selena from behind. "Now, now. Selena. Why don't we train? I have heard that the sea can be used to train our bodies. Let's do it, shall we?"
Selena looked down, falling into deep thought. She ended up sighing. "Sure. Let's do it."
Sera smiled and led her to the beach.
