I'm in a crossover anime world, and I've been transported to Hogwarts twice.

"What a lovely girl. But could it be you who encountered a ghost?"

"Yes, it is."

Erina Nakiri looked somewhat haggard; she had never believed in ghosts or anything like that before.

But after witnessing it with her own eyes time and time again, Erina Nakiri realized that ghosts and monsters probably really exist in this world!

Give me your hand!

Erina Nakiri, without suspicion, reached out and handed it to Genichi Hanyu.

He grasped Erina Nakiri's hands with both of his, but after a moment, Genichi Hanyu released them.

"I can tell you for sure that you have not encountered any ghosts, and there are no marks on your body. So, Ms. Erina, are you sure you have encountered a ghost?"

"I'm sure, absolutely sure!"

Upon hearing what Genichi Hanyu said, Erina Nakiri instantly became agitated, and Genichi Hanyu quickly tried to calm her down.

"Okay, okay, calm down first."

As he spoke, Genichi Hanyu took a bottle of medicine out of his pocket and handed it to Erina Nakiri: "This is a tranquilizer, it won't have any side effects, drink it first."

Erina Nakiri took the potion but didn't drink it; instead, she looked at Senzaemon Nakiri.

Senzaemon Nakiri nodded, and Erina Nakiri then drank the medicine.

After drinking the potion, Erina Nakiri, who had been agitated by the ghost, instantly calmed down.

The medicine, once swallowed, transformed into a cool current that instantly spread throughout the body.

The final rush of energy converged in Erina Nakiri's brain, giving her an immediate sense of coolness.

"Thank you!"

Once she regained her composure, Erina Nakiri immediately expressed her gratitude to Genichi Hanyu.

"Where did Miss Erina encounter the ghost?"

"My room!"

How many times have you encountered this?

"three times!"

"Were all three times in your room?"

"Yes, it is."

Hanyu nodded.

"Then you don't mind if I come to your room to take a look?"

"Of course I don't mind. Please come with me, I'll show you the way."

"Commander-in-Chief Nakiri, please excuse me for now. I need to take care of Ms. Erina's matter first."

After saying a word, Genichi Hanyu left the commander-in-chief's office with Erina Nakiri.

Yukino Yukinoshita stood silently behind Genichi Hanyu, without saying a word.

They quickly arrived at Erina Nakiri's room.

Erina Nakiri was a little scared.

"Could that ghost be in my room?"

"Don't worry, even if it's true or not, I wouldn't mind letting the other party die again."

He pushed open the door and went inside, and then Genichi Hanyu saw Erina Nakiri's boudoir.

He looked around, but Genichi Hanyu did not find any ghosts.

Close your eyes, spread your magic outwards, and sense whether there is any negative energy in the space.

However, Genichi Hanyu did not sense any negative energy.

It wasn't on Erina Nakiri's body, nor in Erina Nakiri's room.

"I'm sorry, Ms. Erina, I didn't sense any ghosts in your room at all!"

"Impossible, I've seen it three times!"

Erina Nakiri was a little agitated, but thanks to the tranquilizer, everything seemed normal.

“There is another way to verify whether what you said is true, Miss Erina, but I need your permission to do so.”

"any solution?"

"I have a way to read your memories, so..."

Erina Nakiri understood instantly.

Yukino Yukinoshita recalled the encyclopedia of spells she had read the previous night, and then remembered what spell Genichi Hanyu had mentioned.

"Leechism?"

Yukino Yukinoshita asked Genichi Hanyu.

"Yes, Legilimency. Yukino, you're really diligent. You didn't finish reading the entire book of spells last night, did you?"

Faced with her childhood friend's teasing gaze, Yukino Yukinoshita blushed slightly and turned her head away.

Yukino Yukinoshita admits that she is a little too curious about magic.

"Isn't there any other way?"

Erina Nakiri naturally didn't want her memories to be seen by others; what difference was there between that and being seen naked?

"I have no other way for the time being. According to my investigation, I have not found any ghosts in this room or on you, Ms. Erina."

After hesitating for a while, Erina Nakiri finally agreed to let Genichi Hanyu read her memories.

"Then I'm going to start."

"Legilimens!"

Genichi Hanyu waved his wand, his consciousness instantly entering Erina Nakiri's memories, but...

Looking at the naked body in the bathroom, Genichi Hanyu couldn't help but sigh, "Even though Yukino is a year older than Erina,... she's completely no match for her."

Then, with a thought, the scene changed continuously, and soon Genichi Hanyu found the memory he was looking for.

Having exited Erina Nakiri's memories, Genichi Hanyu acted as if nothing had happened, as if he hadn't seen anything he shouldn't have.

"I have good news and bad news. Which would you like to hear first, Miss Erina?"

"Good news."

Erina Nakiri spoke decisively.

"The good news is that you, Ms. Erina, are not haunted by ghosts."

"So what's the bad news?"

"The bad news is that you've encountered something even more troublesome than being haunted by a ghost, Ms. Erina."

Genichi Hanyu looked at Erina Nakiri with a sympathetic expression.

After viewing Erina Nakiri's memories, Genichi Hanyu naturally discovered what the ghost she was referring to was.

07 Erina, how about mana replenishment?

The only aroma in the commander-in-chief's office was the wafting scent of tea, and Senzaemon Nakiri's brow was furrowed.

Erina Nakiri was also pale.

Only Genichi Hanyu leisurely sipped the tea brewed from leaves that were worth a thousand pieces of gold.

Yukino Yukinoshita simply watched silently as Yukino was healed.

"If you are already mentally prepared, let's talk about Ms. Erina's problems now."

"Please speak, I am mentally prepared."

Setting down his teacup, Genichi Hanyu looked at Erina Nakiri: "Ms. Erina's problem is more troublesome than being haunted by the supernatural. If it were the supernatural, I could easily solve it."

"But what Erina possesses is not supernatural, but a substitute, a power that belongs to Erina."

"A Stand is an image formed from life energy, which can be used to perform various special abilities or interact with a target. You can think of a Stand as a kind of superpower."

Upon hearing this, Senzaemon Nakiri did not show any joy on his face. Instead, he asked, "Since it's a superpower, why do you say it's not a good thing?"

"To form a substitute, it is necessary to absorb the user's life energy."

Looking at Erina Nakiri, Genichi Hanyu had previously noticed that she looked unwell and assumed it was due to lack of rest caused by the ghost, but now it seemed...

Senzaemon Nakiri and Erina Nakiri understood instantly.

"You mean Erina's life energy isn't enough to awaken her superpowers?"

"Yes, Erina's life energy alone is not enough to awaken a Stand. If it were an ordinary person, their energy would be completely absorbed in an instant, turning them into a dried-up corpse."

"The reason why Miss Erina is still alive is probably because of the nourishing diet she has received since childhood, but even so, Miss Erina's body must be very weak now."

"Lord Genichi, I will spare no effort to save the Erina Nakiri family, no matter the cost."

Senzaemon Nakiri stood up and bowed to Gen Hanyu.

"Sit down. I didn't say I wouldn't help, but how you choose to help is up to you."

Senzaemon Nakiri was stunned, looking at Genichi Hanyu incredulously and asking, "Are there really many other ways to save us?"

"The way to ensure Erina's survival and awaken her superpowers is to replenish her with enough life energy."

"However, simply supplementing Erina's diet with the life energy she has accumulated since childhood is only enough for her Stand to manifest three times. The next time her Stand appears, Erina's life energy will not be enough, and it will then drain Erina's life force."

"The most obvious manifestation is aging, such as wrinkles, gray hair, and a shriveled body."

Erina Nakiri's body trembled for a moment.

If a young girl like her were to end up like what Genichi Hanyu described, she might as well be dead.

"So I can brew potions to replenish Erina's life energy, but the ingredients for the potions need to be collected by the Nakiri family themselves. I will help brew the potions and then charge a certain fee."

"However, it's uncertain whether the Nakiri family has the resources to gather all the materials needed for the potion, and there are some materials that the Nakiri family is unlikely to obtain."

"Moreover, no one can say for sure how many times Miss Erina will need to replenish her life energy."

Senzaemon Nakiri's expression darkened: "Then may I ask what the second path is?"

"To replenish Erina's mana, the simplest way is to transfer someone else's life energy into Erina's body to replenish the life energy that Erina has lost."

"But for ordinary people, the life energy lost cannot be recovered, so it's like exchanging someone else's life for Erina's life. And I don't know if Erina can accept the method of replenishing mana."

Senzaemon Nakiri suddenly seemed to have aged several years.

"Are there any other options besides this?"

"Unfortunately, I don't. If I had a magic stone, I could easily refine an elixir of immortality to solve Erina's problem, but unfortunately I don't."

"Erina, please go out first. I need to speak with Genichi alone."

"Grandpa, I'm the person involved!"

Erina Nakiri refused to leave. As a party involved, she had the right to know and make choices about her own destiny.

Then, ignoring Senzaemon Nakiri, he asked Genichi Hanyu, "Genichi-sama, what method of mana replenishment did you just mention?"

The Nakiri family is wealthy enough to buy lives from those who can't survive.

"Body fluid exchange!"

Senzaemon Nakiri's pupils contracted instantly.

"Fluid exchange?"

Erina Nakiri looked at Genichi Hanyu with confusion.

"Simply put, it's about human reproduction, such as kissing, and for example..."

Erina Nakiri was stunned for a moment, then blushed and shouted, "Stop talking!"

Yukino Yukinoshita, standing to the side, also stared at Genichi Hanyu in disbelief.

Although she felt it was immoral to replenish mana by absorbing other people's life energy, she had nothing to say if the other person was willing.

But she never expected the method of replenishing mana to be so... filthy!
