You can't just become a university teacher. It's highly likely that Ryoko Tamiya's predecessor didn't have the required high-level degree; otherwise, she wouldn't have been teaching at an ordinary high school.
And in human society, academic qualifications are a crucial stepping stone. It's become a widely accepted notion to look at qualifications first, regardless of knowledge or ability.
If you don't have connections or acquaintances, a lack of qualifications can be quite despairing.
Ryoko Tamiya's answer made Kurozawa inwardly chuckle; he couldn't help but laugh out loud.
She looked at Kurozawa, first saying with a serious tone, "This body's qualifications are insufficient." Then, her tone shifted, and she said, "So I forged them."
"While this carries the risk of exposure later, I don't plan on staying long anyway."
As they spoke, the two walked into Higashi Fukuyama University.
University campuses are relatively loosely managed, and even an outsider like Kurozawa easily blended in.
Wide, clean paths, rows of cherry trees adorned with vibrant blossoms, and the youthful energy of students sweating on the nearby basketball courts filled the air, bringing a hint of nostalgia to Kurozawa's eyes.
He didn't wander around the campus but followed Ryoko Tamiya directly to a spacious classroom that could accommodate over a hundred people.
The seats in the classroom were arranged in tiered rows.
Because they arrived just in time, quite a few people were already in the classroom. An elderly lecturer with temples streaked with white, wearing black glasses, was already standing at the podium, his back to the class, writing on the blackboard.
As soon as she entered the classroom, Ryoko Tamiya effortlessly sat in the front row, sitting upright and proper. She even took out a pen and a small notebook, looking as if she intended to take notes.
Kurozawa, on the other hand, suddenly felt a bit sleepy.
Although Kurozawa came here out of curiosity about what Ryoko Tamiya wanted to hear in her last class, for some reason, as soon as he was in this academic atmosphere, he couldn't help but yawn continuously, feeling incredibly sleepy.
Of course, with Kurozawa's self-control, he could easily dispel the drowsiness and regain his energetic demeanor, but he didn't. He simply leaned lazily on the desk, supporting his head with the back of his hand.
Soon, the old teacher finished writing the topic for the class, then turned around, took a sip of water, and cleared his throat.
The old teacher seemed to recognize Ryoko Tamiya; he gave her a gentle smile before looking up and scanning the young university students.
"Altruistic behavior, that is, actions undertaken for the benefit of others."
He pointed to the words written on the blackboard, [Altruistic Behavior Among Biological Populations], and began.
Kurozawa opened one eye slightly, showing little interest, then closed it again, looking drowsy.
He withdrew all his Fighting Spirit, minimizing his presence. Even though he was in the noticeable front row, the old teacher only glanced at him before looking away as if he hadn't seen him.
Ryoko Tamiya beside him, however, was listening intently. Coupled with her youthful appearance, she blended perfectly into the classroom environment, looking somewhat like a female student.
Without actively clarifying her identity, it's likely few people would take her for a teacher.
"Opposite to altruistic behavior is self-interested behavior. Most organisms act based on self-interest."
"However, altruistic behavior, which damages one's own interests and offers no benefit to oneself while helping others, is also not uncommon in human society and happens frequently."
Ryoko Tamiya bit the tip of her pen, scribbling in the notebook she carried with her. She wasn't sure what she was recording; perhaps it was the old teacher's words, or perhaps some of her own thoughts and insights.
On the podium, the old teacher's expression remained unchanged as he spoke fluently.
"And outside of humans, many animals also exhibit altruistic behavior."
"For example, ants. When they need to cross a river, they will form an 'ant ball.' The ants on the outer layer voluntarily sacrifice their lives so that the ants on the inner layer have a chance to survive."
"For example, bees. When facing external enemies, they will fight to the death to protect the hive, regardless of their own lives."
"..."
As the old teacher's steady voice continued, Kurozawa was on the verge of falling asleep, feeling as if he were being hypnotized.
Just then, the sunlight outside the window was soft, and a faint fragrance drifted in on the breeze, so he closed his eyes and took a nap.
Some time later, when Kurozawa opened his eyes, the class was not yet over, but the old teacher's topic had shifted from altruistic behavior to self-interested behavior.
"The physical bodies of all organisms are puppets of their genes."
"What's important is never the species, nor others, but always oneself."
"Altruistic behavior, to some extent, is also a form of self-interested behavior aimed at gaining a sense of accomplishment or satisfaction; it's also for oneself."
"We humans can form families, form societies..."
As time passed, the crisp sound of the class bell rang, and the old teacher's words abruptly stopped.
Although he hadn't finished speaking, he showed no intention of extending the class. He directly announced the end of class and began packing his textbooks.
Ryoko Tamiya, carrying her pen and notebook, walked to the side of the podium under Kurozawa's gaze. Then, with a faint smile, she chatted with the old teacher, who was also happy to answer her questions.
As for what they were talking about, Kurozawa had no interest in listening.
He looked out the window at the crowd, in a half-asleep state, with little expression on his face, appearing just like a student who knew nothing of the world.
On the podium, after chatting with the old teacher for a few minutes, Ryoko Tamiya returned.
The two left the university campus together, not taking a bus, but walking towards the City Hall Building.
Halfway there, Kurozawa looked at Ryoko Tamiya and asked, "If you merge with my body, you will lose your autonomy and will no longer be able to absorb knowledge as you wish."
"So, are you willing to give up your hobbies and interests?"
Ryoko Tamiya was silent for a moment, then smiled, "Everything has a price. If I want to survive the upcoming human siege, I have no other choice."
"Only with you is there a glimmer of hope for survival."
The actions of the Blade Breakers department have become increasingly blatant and public.
Undercurrents are also swirling online. In various cities across Japan, many encirclement and suppression operations have been captured by passersby and uploaded. On a global scale, some countries are even more aggressive.
For example, the United States and the Russian Federation.
Their various actions practically scream "exterminating aliens" from their foreheads.
The number of Parasitic Organisms on this planet is rapidly dwindling. Compared to countries with stronger capabilities, Japan's efficiency is already quite low.
According to Ryoko Tamiya's understanding, the Parasitic Organisms in the East have been almost completely wiped out under the highly efficient, unified operation of the entire country, leaving only a handful.
She had also observed many airports, high-speed train stations, and other places, discovering that these transportation hubs had, at some point, been equipped with the latest security screening equipment, and soldiers with live ammunition were stationed nearby.
It has also become impossible for Parasitic Organisms to escape to less developed countries.
