Crossover anime, a daily life that begins with hunting supernatural beings.

Carrying his shoulder bag in one hand, he walked past groups of classmates, not knowing a single familiar peer in this school, and strode towards Sakurai, who was heading towards the gate.

Then...

He was caught red-handed by the icy teacher with her arms crossed and a frosty expression.

First of all, one thing is certain: being blocked at this point is definitely not a good thing.

Looking at the aloof teacher in front of him, Sakurai, who was carrying his schoolbag in one hand, couldn't help but mutter something under his breath; he had a bad feeling.

“Come with me.”

The teacher, whose purpose was to help Sakurai from the beginning, left those words and then turned and walked away.

With a silent sigh, Sakurai suppressed the urge to run away and obediently followed his teacher.

As for why he, as someone from another world, is so obedient, and why he, all alone, still has to spend time learning this...

It's all thanks to the teacher in front of us.

The teacher's name is Kirisu Mafuyu. A month ago, she found him in the apartment where he was born, and he was suffering from amnesia. Whether it was his identity certificate or a series of other procedures, or even his survival until now, it was all thanks to the help of this teacher who is cold on the outside but warm on the inside.

Otherwise, if he couldn't even remember his own name and only had one place to live, he wouldn't have been able to survive in this world at all.

so...

Sakurai was very grateful to her, thanking this cold but very responsible teacher.

Even their speech, behavior, and lifestyle habits were learned from her.

So even though he couldn't concentrate in class like he was sleepwalking, he still came to school every day obediently.

Is there something you need from Mafuyu-sensei?

Following behind Mafuyu at a leisurely pace, Sakurai tried to glean something from the other's figure.

Sure enough, we couldn't see anything.

Kirisu Mafuyu's poker face far surpasses his level; trying to glean anything from her is simply too arrogant.

"Please take a seat."

Finally, the two arrived at an empty activity room, where Kirisu Mafuyu, who had sat down first, gestured for Sakurai to sit down as well.

"Yes."

Sakurai sat obediently opposite Kirisu Mafuyu, his head slightly lowered so that Kirisu Mafuyu wouldn't see his eyes, quietly waiting for the other's judgment.

"Have you found any clues from the past? Anything is fine. Have you remembered anything?"

Sitting upright, Kirisu Mafuyu looked at Sakurai with her back straight.

Looking at the somewhat restless Sakurai, Kirisu Mafuyu asked the question.

"No, I'm sorry, I still can't remember anything."

"My mind is still filled with memories of this month."

"As you know, Mafuyu-nee, the phone number the landlord left is unreachable."

"Furthermore, Mafuyu-nee has also gone to talk to the principal."

"Aside from the character 'Sakura' which can be vaguely discerned, the remaining three characters on both the electronic and paper files are garbled characters."

"I am a guy who has no memories or past."

Sakurai casually shrugged and answered Kirisu Mafuyu.

"It's as if some special power has erased my existence."

"All that's left are dregs that don't even know who they are."

"Isn't that why Mafuyu-nee named me [Sakurai Eito]? It's the same name as that Kamen Rider, Sakurai Yuuto, who burned his memories to become power, and it's only one character different from his name."

"I really like this name."

"Looking back, it seems I've still gained nothing."

That was more than three weeks ago; perhaps he, from another world, inherited this body.

A visitor from another world with no memories, and a completely new him who merges with a body that also has no memories.

He had searched the apartment thoroughly using his instincts, but the result was that he had nothing left except that single-person apartment.

Then, while he was lying in bed, so lacking in common sense that he didn't even know to eat, having skipped several days of classes, he welcomed his first guest.

They practically forced their way into his room from the property management office. Kirisu Mafuyu, who came to his door, seemed cold and aloof, but after learning about his situation, she still chose to do everything she could to help him.

Unlike others who, when faced with the same situation, simply hand him over to the police and then comfortably leave him alone.

They carefully taught him everything, including basic common sense and other aspects, teaching him how to dress, wash, and clean his body, as well as how to speak and write.

After confirming that he had basic self-care abilities, they even contacted trustworthy police officers to help him find clues about his past.

To be on the safe side, he even acted as a middleman between him and the police officer, relaying messages between them and avoiding direct contact between them.

In the end, he gained nothing, but the gratitude he felt for being helped made Sakurai willing to follow Kirisu Mafuyu's plan and try his best to live on.

Sakurai had thought about it too. Even if he could never remember his past memories, it wouldn't be bad to live like this.

After all, the forgotten past wasn't really his, right?

Sakurai Eito's name is surprisingly nice, isn't it?

However, unlike Sakurai, who simply let things take their course, Kirisu Mafuyu didn't think that way.

Even if it meant squeezing out her leisure time outside of school, she spared no effort in helping Sakurai find clues about the past.

Not letting go of even the slightest possibility, expending heart and energy, sacrificing their free time and personal connections—this is the teacher named Kirisu Mafuyu.

He was also the first trustworthy person he met in this world.

So, even for the sake of such a teacher, I still have to find my past.

Even though his body was instinctively resisting, he would still try his best to continue searching.

"Teacher, please rest assured, I will continue to strive to live in this world."

In order not to let this sentiment go to waste.

Picking up his schoolbag, Sakurai stood up and gave a strong thumbs-up.

3. Tutoring and Hunting

"That's good. Now let's get down to business."

Kirisu Mafuyu nodded, satisfied with Sakurai's answer, and then said this expressionlessly.

What...what?

Sakurai's smile froze as she opened her eyes wide. She turned to look at Kirisu Mafuyu, who had put down her lesson plan. Was what she had just said not the important matter?

Mafuyu-nee isn't just here to check on my memory problems, is she?

Sakurai, who had just relaxed, tensed up again.

“I know about your situation, Sakurai, but apart from world history, you haven’t listened to a single word of any of the other courses, have you?”

"You're completely out of it in class. Other teachers have already complained to the principal about your situation. If this continues, you could be expelled for 'disobeying the teaching arrangements'."

Kirisu Mafuyu stated this cruel fact in her still icy tone.

"But..."

I didn't want to go to school in the first place.

He opened his mouth, but ultimately didn't say the second half of the sentence.

“I understand your situation. Due to amnesia, you missed out on elementary and junior high school education compared to other students.”

"But you should know that this is not a reason."

Kirisu Mafuyu quietly watched Sakurai.

"Yes, I understand."

Nod honestly.

"To help you catch up with the teaching progress, I have applied to the principal for this activity room. You will need to come here every day after school, and I will help you catch up on the lessons you have missed."

As a qualified teacher, Kirisu Mafuyu believed that there should be no problem with the elementary and junior high school curriculum, and made this decision after talking with the principal.

She was unwilling to give up on a talented student like Sakurai.

"If Sakurai can learn how to survive in modern society in just one day after losing his memory, his study habits shouldn't be too bad."

"Catch up on your studies before the next test."

As she said this, Kirisu Mafuyu handed a stack of notebooks to Sakurai.

"Yes."

Although somewhat reluctant, it turned out...

I don't want Mafuyu-nee's hard work to go to waste.

Even if it's difficult, just try to learn it.

Big deal...

I've tried a little harder.

Sakurai also knew that if he really wanted to put in the effort, given his circumstances, he wouldn't be so unwilling to listen.

......

......

The two hours of study time passed quickly. Sakurai, having declined Kirisu Mafuyu's offer to take him home, watched Kirisu Mafuyu leave after finishing his tutoring session.

"So..."

"I should get ready too, go home."

Sakurai patted his face, feeling a little dizzy and lightheaded after the tutoring session, and rubbed his temples.

Sakurai breathed a sigh of relief and couldn't help but turn around to look at the classroom behind her.
