Leon Alex, the strongest warrior of the Eastern Kingdom—a swordsman renowned across the world, a transcendent Sword Saint—was now doing something he could hardly have imagined himself doing before—

Walking through the women’s section of a hot spring, on his way to secretly check on a girl and see what she was doing.

He was simply too worried about whether Fio and Vivian might do something strange in their luxury private room. He had to see for himself.

On impulse, Leon had bought an invisibility potion from a black-market merchant, intending to sneak into Fio and Vivian’s hot spring.

But now that he was already inside, there was no point in backing down.

This invisibility potion was a little unusual. It wasn’t like the invisibility spells mages used in actual combat—

“Sword Saint, remember: this invisibility potion erases your presence. It doesn’t actually make you invisible. You can see little stones by the roadside, for example, but no one pays them any attention… That’s how this potion works. So if someone takes particular notice of you, the effect will wear off. Please be very careful when you use it.”

That was what the black-market merchant had told him.

But the potion couldn’t erase the presence of his clothes. So after entering the men’s bath, Leon stripped, drank the potion, and made sure other people could no longer sense his presence before finally working up the courage to sneak into the women’s section.

Leon figured this was probably the craziest thing he’d ever done in his life. Even going alone to fight the Demon King Diablo seemed like nothing by comparison…

Surrounded by a group of women, Leon felt like he was going insane.

Leon told himself that none of the other women were worth looking at. Only Fio, with her petite figure, was truly worth admiring.

Even as he repeated that to himself, women kept passing in front of him, making his blood race and his body grow hot and restless.

The room was filled with a dangerous fragrance, almost too much for Leon to bear. To calm himself down, he started another round of self-suggestion.

Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women. Find Fio. Don’t pay attention to the other women…

Leon fought to keep himself in check, and finally managed to suppress the restlessness in his heart.

After what felt like an age of torment, Leon found Fio and Vivian’s room. He swallowed hard, then slipped inside with the resolve of a man going to his death.

“Ahaha… This is my first time at a hot spring!”

“Have you never been to the City of Sunrise before, Fio?”

“Mm. Before, I always stayed in the Land of Everlasting Snow—uh, never mind.”

Leon heard his younger sister and Fio talking. Through their shadows on the glass, he saw the two of them changing clothes. He quickly lightened his steps, eased the door open little by little, and slipped into the hot spring first.

Since this was an expensive luxury private room, there was no one else here besides Fio and Vivian… and one suspicious Sword Saint.

That must be Fio. She’s coming. I’d better hide farther away so she doesn’t spot me.

Leon tucked himself into a corner of the hot spring, away from the center. That way, even if Fio and Vivian came in, they wouldn’t see him.

Leon lowered his head, determined not to look at the two girls as they entered the bath.

He absolutely wouldn’t commit such a shameless, perverted act of peeping. He was here to confirm a few things. Otherwise, what made him any different from a creep?

Leon, a man of unshakable principles, declared that he would never do anything so ungentlemanly.

The sound of bare feet pattering against the damp floor reached him. Hearing that heavenly sound, Leon raised his head.

He saw two pairs of girls’ legs, but all his attention went to the smaller, fairer feet. At a glance, he knew they belonged to Fio.

If not for his Mind Like Still Water skill, he probably would’ve exploded like a bomb by now.

Fio and Vivian entered the hot spring, chatting and laughing. Their voices weren’t that far away, but Leon couldn’t make out what they were saying.

The two of them didn’t notice Leon at all. Even though he was standing right there in the hot spring, they paid him no mind. The knot of fear in his throat finally loosened a little, and he began to feel grateful to the black-market merchant.

Growing bolder by the moment, Leon started thinking that since he couldn’t hear their conversation, he’d have a better idea of what was going on if he got a little closer.

Should I get a little closer? Just a tiny bit.

Leon slowly shifted through the hot spring, inching closer in the most careful way he could, making sure the two of them wouldn’t notice him.

It’s fine. The invisibility potion is reliable. As long as Fio and Vivian don’t become aware of you, they won’t find you. Leon tried to soothe his own nervous, excited feelings.
