Summoned as a Heroic Spirit in Anime World

"Yes!"

Saeko Busujima stepped into the bathtub without hesitation.

Marikawa Shizuka quickly followed, giggling as she ran into the tub.

Only Yotsuya Miko hesitated.

"Miko?"

Kaito turned his head.

Miko let out a startled cry, crouching down and covering her chest.

Her face, neck, and even her ears were flushed red.

"S-Sensei, don't look," Miko whimpered softly.

"You can't temper your body while wearing clothes," Kaito said helplessly.

"You can start cultivating directly if you want, but the effects will be much worse than after tempering."

"It's up to you."

Miko bit her lip, hesitating for a few seconds before finally standing up, still hunched over and covering herself.

Kaito turned his head away, not looking at her further.

"Hehe, Sensei can look at Shizuka~"

As soon as Kaito turned his head, he heard a splash of water.

Shizuka lunged at him, wrapping her arms around his waist and pressing her full weight onto his legs. She looked up at him with a mischievous grin.

"Sit down properly!"

Kaito gave her a light knock on the head, scolding the three-headed monster.

"Ow, Sensei is mean!"

Shizuka's eyes welled up with tears as she sat back down, pouting.

Watching Shizuka's retreating figure, Kaito couldn't help but reflect.

Should I have imitated Master Subodhi and knocked her on the back of the head three times?

But then he realized that with Shizuka's brain, she probably wouldn't understand the meaning behind three knocks. Instead, she'd likely just cry and ask why he hit her. With that thought, he let it go.

By now, Miko had also entered the tub, her face still flushed with embarrassment.

"Relax your body."

"I'm going to start the tempering process."

With that, Kaito channeled lightning energy into the tub.

The three women immediately cried out.

"Huh?!"

Saeko's reaction was relatively normal.

Miko tried to suppress her voice.

But Shizuka...

Kaito's face darkened as he looked at Shizuka, who was blushing and moaning.

Can you not sound so... indecent?

People who don't know what's happening might think we're doing something inappropriate.

Soon, all three women were immersed in the tingling sensation of the electric current.

Kaito controlled the lightning, using it to activate the medicinal properties of the herbs in the tub while simultaneously stimulating their bodies. He slowly unblocked their meridians and blood vessels, cleansing their bodies of impurities.

Humans consume grains and breathe in polluted air, which over time leads to the accumulation of toxins in the body, blocking meridians and blood vessels.

Even Saeko, who had the best physique among the three, had many blocked meridians.

Kaito's task was to clear these blockages, nourish their meridians with the medicinal herbs, and infuse their bodies with lightning energy to make it easier for them to cultivate the Thunder Spell later.

Time passed minute by minute.

After about half an hour, Kaito spoke.

"That's enough."

The three women seemed reluctant to stop.

At first, the process had been painful, but as Kaito gradually increased the intensity, they began to feel a strange pleasure, becoming addicted to the mix of pain and euphoria.

However, when they opened their eyes, they were shocked by what they saw.

The once-clean tub was now filled with murky, muddy water, as if someone had dumped a bucket of dirt into it.

"Wash yourselves off."

Kaito left the bathroom, grabbing a bottle of cola from the kitchen fridge before sitting on the sofa.

He sipped his drink while flipping through TV channels, eventually settling on a celebrity prank show.

I have to admit, even though the people here aren't great, their variety shows are pretty entertaining.

Kaito, who had never been interested in variety shows before, found himself unable to stop watching.

As he laughed, the three women emerged from the bathroom.

They were all dressed in yukatas, and even Miko, who had been the most shy earlier, looked excited and thrilled.

"Sensei, you're so good to us!"

Shizuka cheered as she rushed over, throwing herself at Kaito and hugging him tightly.

At 27 years old, Shizuka was nearing her thirties, just like Hiratsuka Shizuka.

Despite her natural beauty, her skin couldn't compare to that of a younger girl.

But after washing off the impurities, Shizuka noticed that her skin had become smooth, radiant, and elastic, almost like a newborn baby's!

Saeko and Miko also didn't pull Shizuka away this time, instead looking at Kaito with gratitude.

Saeko, who had been practicing swordsmanship since childhood, had accumulated many hidden injuries over the years.

Her hands were calloused from years of training.

But after the tempering process, all her old injuries had disappeared, and the calluses on her hands were gone, leaving her skin smooth and soft.

Miko felt the least dramatic change but still noticed a surge of energy in her body.

She even felt like she could run a kilometer without stopping!

No—she wanted to run a marathon!

And despite staying up late last night due to excitement about learning the Thunder Spell, she now felt completely refreshed.

Kaito smiled and patted Shizuka's head, enjoying the sensation of her ample body pressing against him.

But soon, things took a turn.

"Hehe."

"Sensei is reacting~"

Shizuka giggled as she reached out to grab him.

Miko turned her head away, her face red, but couldn't resist sneaking a glance.

Saeko, on the other hand, watched openly, a smile on her lips.

Kaito had given her such a great gift, and his swordsmanship was incredible.

Plus, he was handsome and around her age.

Even if he asked her to sleep with him or bear his children, she wouldn't refuse.

"Smack!"

Kaito gave Shizuka another light knock on the head.

"Go stand over there."

"Ow?"

Shizuka pouted, clutching her head, but obediently climbed off Kaito and stood with Saeko and Miko, looking both defiant and submissive.

"Now, I'll teach you the proper Thunder Spell."

"Saeko, you should learn it too."

"Even though it might be difficult for you, it'll still be beneficial."

"Yes!"

Touched by Kaito's kindness, Saeko knelt down and bowed deeply in gratitude.

"Saeko thanks Sensei for teaching her."

Miko and Shizuka followed suit, kneeling and bowing as well.

"Miko/Shizuka thanks Sensei for teaching us!"

"Alright, no need to be so formal. Get up."

The three women stood up, kneeling respectfully on the floor and looking up at Kaito with admiration.

With the curtains drawn and the dim lighting, Kaito, sitting on the sofa, couldn't help but feel like a cult leader with hypnotic powers, secretly brainwashing the three of them in the villa.

"Listen carefully..."
