"yes."

In the training grounds of the castle, Satanie began her own training, or rather, to demonstrate her abilities... Unlike Vera, who received cramming education, Ira preferred to teach according to individual aptitude.

"Begin the test of Mana's explosive power... Flow the maximum amount of magic into my body within one second."

Ira, who was holding hands with Satan Ye, felt the mana flowing into his body. He nodded without comment and proceeded to the next test: "Next is control. Divide the amount of mana you just received into twenty portions and input them at a constant speed over twenty seconds."

"Next is utilization rate..."

"The most basic physical fitness test, but unfortunately there's not enough space; oh well, just punch me with all your might... Hmm, okay, I got it, so next..."

"..."

"..."

"Ha-hu... Ha-hu... Ha-hu..."

Amidst Satan's panting, Ira continued to write something down with paper and pen. Vera curiously leaned over to look, only to see a table composed of horizontal and vertical lines, along with a dense mass of numbers and symbols.

Hmm, I don't understand!

"So, how skilled is the Demon King?"

"She doesn't seem like a maid, more like a mother or older sister," Shirina asked with concern.

"It's so bad that it's impossible to pass without saying, 'Teacher, I'm willing to do anything as long as I can pass the exam.'"

Vera said this, even though she couldn't understand the data but could feel the flow of mana.

Sylvia: "Huh?"

Satan Leaf: "Huh?"

...

"Bang!!!"

"Ouch! Ugh... ugh..."

Ira delivered a chop to Vera's head, then grabbed the back of her neck and said, "It is indeed very bad, but for a Demon King, the key is not combat power but the minimum ability to protect oneself."

Sylvia: "So?"

So, if I work really, really hard, even if I don't say "I'm willing to do anything," I can barely pass... probably.
