Vol 3 Chapter 26 – All Female Knights Have Weak Butts【Vol 3 – The First Knight Commander is a Dark Elf Half-Succubus Who Hates Men】

The night of the day when I worked up a good sweat for the first time in a while against Shion and Yuna-san.

At the campsite deep in the forest, just as I was about to sleep, Yuna-san called me out.

The fact that she didn’t call me out early meant she wanted to avoid being seen.

After all, the Knight Order Commanders’ mock battle drew tremendous attention during the day.

The three of us—Yuna-san, Shion, and I—sat by a small stream a short distance from the campsite.

Even after sitting down, Yuna-san kept looking around.

She seemed quite concerned about being seen by anyone from the Knight Order.

“Yuna-san, there’s no one around, so it’s fine.”

“If Master says so, I’m reassured. …I know I’m being too cautious, but I really don’t want my weaknesses overheard. Please forgive me.”

“Weaknesses?”

“Yes. I want to hear your honest impressions from fighting me, Master. Bluntly—where do you think my weaknesses are?”

“Hmmm.”

Weaknesses, huh.

Yuna-san’s combat style had no openings with both long-range magic attacks and close-range combat, her combinations were good, her attack power was strong, and her defense was skillful.

Since there was nothing particularly outstanding, my impression was that she was an excellent, solid all-rounder.

The polar opposite of Shion, who was like a romance cannon specialized in talent.

“Yuna-san’s weaknesses… I can’t really think of any?”

“Please don’t say that. After all, Master is much stronger than me and has keen observation. I believe there must be something that Master can see that I haven’t noticed myself.”

“Even if you say that…?”

“Anything trivial is fine. Master is the only one I can rely on.”

Being begged and bowed to like that, I’m weak to that.

After thinking back to this afternoon’s sparring session multiple times, trying to squeeze out some opinion:

“Well, if I had to say… your body’s a little stiff, maybe.”

“What?”

Yuna-san blinked, as if she’d been told something unexpected.

“Does it look that way to Master? But I make sure to do flexibility exercises every day…”

“For a typical knight’s level, it’s plenty. But at Yuna-san’s level, you need to aim for far greater heights in flexibility too. Your attacks are mainly close-quarters combat, after all.”

“Hmmm… I can’t readily believe it, but if Master says so…”

“Well, to be precise, it’s not just flexibility in the general soft-body sense. It’s more like a mix of muscle and tendon elasticity, range of motion, and various other microscopic output factors.”

“Hm?”

“To put it simply, level up the quality of your muscles, tendons, joints, and bones. If you level up the quality of those areas, flexibility will naturally follow.”

“Wait a minute. How do I train something like that…?”

Well, you’d think that.

Normally, training muscles equals increasing muscle mass, and it’s impossible to improve the quality itself without increasing muscle volume.

Training tendons, joints, and bones is also impossible, of course.

But here’s the thing.

During my time in what felt like an eternity in that subspace darkness, I devised a revolutionary training method that improves the quality of muscles, tendons, bones, and everything else all together.

However, this method puts quite a load on the body, so I can’t recommend it to amateurs—their bodies wouldn’t hold up.

It’s only possible with someone whose body is as thoroughly trained as Yuna-san’s.

When I explained that (excluding the subspace stuff), Yuna-san opened her mouth in shock.

“I-Is such a thing really possible…? Is Master a god…!?”

“That’s way too exaggerated. Well, I think it’s possible for Yuna-san, so you could give it a try.”

“Me too, me too! Master, I want to do it too!!”

“For Shion… it’ll have an effect, but not as much as for Yuna-san.”

Shion’s been abnormally flexible with great spring in her body since childhood, and she had natural talent from the start. Even I was surprised back then.

Thinking about it now, this might also be a succubus trait.

“However, this training method has a slight problem.”

“What kind of problem? No, whatever the method, the training Master speaks of is far too attractive. I swear I’ll overcome any hardship.”

“No, it’s not that difficult, but it’s more about how to teach it…”

Specifically, if the other person were a man, there’d be no such concerns at all.

This problem only arises because the other party is Yuna-san or Shion.

“Uh, it looks like a normal massage. But since I have to thoroughly massage even the muscles deep in the body…”

“I don’t hear any problem at all?”

“For example, I really massage the pectoralis major and gluteus maximus. Very vigorously.”

“Huh!?”

“Also, for example… to loosen deep into the anal sphincter, where I need to deeply insert my fingers… well, that sort of thing.”

“Y-You mean the butt!? Is it butt confirmed!?”
