Without Alona, ​​I can only use the airdrop system.

A month passed after the teacher and Hina returned to their own world.

Nothing significant happened during that time, and there was no news of the last student from the parallel world arriving here.

The teacher's job consisted of daily routines, including spending time with Hina and delivering food.

The only thing worth mentioning is that Zhang Ziling brought another Nikki to Kivotos as a guest. This Nikki's name is Helen, and she has blue hair and looks very beautiful in her white naval uniform.

During her week-long trip, Helen promoted the concept of a navy to several colleges, arousing the curiosity of many students, but also surprising that most colleges in Kivotos did not have a navy.

The only group that could understand and plan to put Helen's ideas into practice was the student council of the Odyssey Maritime College.

After hearing Helen's idea, they came up with the plan to build the naval force that Helen had mentioned.

However, the teacher did not stop them, but only warned the Odyssey students not to use it for wars between schools.

In addition, Zhang Ziling and Helen also lived in the same room.

Sometimes, when teachers go back to their rooms to sleep after working the night shift, they can hear the sounds of men and women having sex coming from outside their rooms as they pass by.

Upon seeing this scene, the teacher felt an overwhelming sense of sympathy for Labi, Anis, and Nien.

In short, every second we spend now is a peaceful daily routine.

Until that evening.

Within the Arian Academy, in a dense forest.

Arius's special squad of four was training right there.

"Today's training is complete, everyone. Let's go back."

Saori reminded the other three team members present.

"Ugh... It's finally over..." Hiyori leaned against the nearest tree, panting heavily.

"Since the Arios Academy was reorganized, we haven't had any proper training in a long time, and our combat skills have become quite rusty," Misaki complained.

“However, I feel that life has become more fulfilling than before,” Yazuko said softly. “Thanks to the teacher, the conditions at Arios Academy have improved a lot compared to before.”

“…The princess is right.” Saori looked relieved. “Looking back, if it weren’t for the teacher’s suggestion, we would probably be homeless.”

"Moreover, he also taught us a move called 'half-reverse,' which we all found very useful."

"No matter what the outcome, as long as we don't separate, that's fine." Azuko's gentle smile also healed the other three people present.

Just as they were about to go back to rest, a black hole suddenly appeared, and one of the students, covered in wounds, rushed out of it!

"Hmm... do I... count as being back...?"

The student had black hair in a ponytail, and beneath her well-equipped gear was a toned figure and a resolute, golden gaze that seemed to have been tempered by war.

However, when she saw Saori and the other three, her tense expression suddenly began to relax.

"It's Saori-neechan! Thank goodness, I did it..."

Before he could finish speaking, the other person fell into a deep sleep due to complete relaxation.

Fortunately, Saori caught her in time.

"That's strange." Saori was a little confused, then looked at the three people behind her. "Do you know her?"

All three of them shook their heads.

“I’m still wondering why she knows you,” Misaki added.

"Could it be... that she's the student from the parallel world mentioned in the Federation Student Council's announcement?" Saori suddenly remembered the notice sent by the Federation Student Council more than a month ago.

At that moment, Saori took out her phone and dialed a number:

"Teacher... um, it's me. I have something to report to you..."

Some time later, at the Arius College infirmary.

The black-haired girl with a ponytail slowly opened her eyes, and what came into view were the four members of Arius's team.

"Sister Saori!" The black-haired girl with a ponytail immediately became alert, grabbed Saori's arm, and said to Saori, "Please, please don't aim at the teacher's head, or you'll regret it!"

"What are you talking about, classmate?" Saori looked at the girl with a blank expression. "Why would I hurt the teacher? Besides, I'm no match for the teacher right now."

"???" Now it was the girl's turn to be confused. "No, Saori-nee, I'm also Arius's student! My name is Emiya Harumu, and you're the one who picked me up! You taught me a lot of my moves!"

“…” Saori shook her head. “I’m sorry, but at least in this Gevotos Arios Academy, there isn’t a single student named Emiya Harumu.”

"Did I fail to return to the past...?" Emiya Harumu lowered her head, her hands clenched tightly. "Damn it, was it all for nothing...?"

At that moment, a golden light flashed, and when it dissipated, the teacher's figure was revealed.

"Hello, Harumu Emiya, I'm the teacher of this Gewatos." The teacher then asked Harumu Emiya, "Could you tell me what happened in your world?"

Emiya Harumu looked at her teacher, who was completely different from the one she remembered, and immediately realized her current predicament.

“It seems I’ve entered a parallel world…” Emiya Harumu’s eyes dimmed. “It’s all too late.”

“It’s okay, I believe our teacher can do it.” Saori said seriously, which was unusual for her. “He is very strong, and he can also invite a lot of powerful companions.”

"I believe the teacher can solve the problems in your area of ​​Kivotos."

"But it's too late!" Emiya Harumu suddenly shouted, "They're all dead here! They were all killed by those two bastards Beatrice and the Underground Living Beings!"

"Even if I could go back and kill those two newborns, what then!?" Tears streamed down Shinobu Emiya's face. "Everyone who sacrificed themselves for me is gone..."

"I failed to protect them; I let them down..."

At this moment, Harumu Emiya was crying her eyes out, and no matter how much Saori and the others tried to comfort her, Harumu Emiya couldn't stop sobbing.

Fortunately, the teacher had already extracted the key information from Emiya Harumu's words—Beatelitch and the two underground dwellers.

These two, like the two she encountered, have likely gained power outside of the world of Giwatos, and this power is something Emiya Harumu would find difficult to deal with.

However, we'll probably have to ask the child about the exact timing once he's calmed down.

To solve Emiya Harumu's problem, the teacher will probably have to use the power of time travel.

However, currently, the only power teachers possess related to time is the control over the flow of time; they have not yet grasped the ability to travel through time.

As for time travel, the teacher thought of two people.

"Saori, you guys keep an eye on Harumu, I'm going to make a phone call." After telling Saori and the others, the teacher walked to the door, took out her phone, and dialed the number for Drunken Mist Ghost Island.

After contacting Drunken Fog Island, the teacher then used a walkie-talkie to contact Zhang Ziling.
