Ultimate Being from the Tokonosu City

"Oi, shut up!" 

Teshima-sensei, who was furious, couldn't control his emotions anymore, but Isao remained silent and stared at the man banging on the school's gate. Even though he knew that a disaster was about to bring destruction to this world, he couldn't help but be in a daze when he saw everything was about to start for the first time, especially when everything had been normal before he came to school. 

This morning, not only did he eat a Western style of breakfast that consisted of milk, omelet, bread, and even salads, but he even played "Mozart - Requiem" to welcome his unfinished reincarnated life, thinking that he would die being bitten and become "them" in this world.

However, he quickly calmed down, especially when he had just gained the system. 

His system was unique, and he also gained the power of a Tosa Dog, a Maine Coon Cat, and a fly. 

While he had yet to fully understand all the capabilities of his system, he was sure there were many interesting abilities that he hadn't tapped, and he was sure that he could face the disaster in this world smoothly. 

"Oi, didn't you hear me?! Shut up!" 

Nevertheless, Teshima couldn't continue to scold Isao as he became furious at the man who had been banging on the school's gate. He looked at the man, observing him for a while before he decided to release his anger on him since he could see this man was a pushover, and while he didn't want to admit it, he was... a bit afraid of Isao. 

No, he wasn't scared, but it was just troublesome to be violent with the student, so to gain the masculinity that he had lost, he decided to show how manly he was in front of everyone by stopping this crazy man who had been banging the school's gate. 

"Sensei, please calm down." 

Isao glanced at the only female teacher by his side, who said those words and showed her concern to Teshima. 

Kyoko Hayashi. 

Even though Kyoko was in her early 30s and had this frown on her face as if she had been dissatisfied with her life, Isao had to say she was charming. She had light brown eyes with glasses and reddish-brown hair, which she kept in a loose ponytail with long strands hanging down in front of each ear, giving off the charm of a mature woman. 

Yet, the most charming part of Kyoko was her breasts. 

Isao wasn't sure why, but many of the women in this world had such naturally gigantic breasts. They weren't formed artificially but were born naturally and formed into the beauty of nature that was appreciated by many men. 

Nevertheless, even if he wanted to enjoy this beautiful scenery, he knew that this wasn't the time, and he wasn't so hungry that he would attack every charming woman that he saw on the street. 

'If I am not wrong, she should be close to Teshima, right?' 

Isao looked at Teshima, who had walked toward the man who kept banging on the school's gate. 

"It's okay, Hayashi-sensei. Leave this matter to me." 

Hearing Kyoko's concern, Teshima slightly pulled his sleeve, showing his muscular arm, which he had trained due to his job as a physical education teacher. 

"Sensei, that person might be dangerous." 

Usually, Isao would be silent, letting this guy die, but this time, he decided to remind Teshima. He had decided to become a good person, so even if Teshima was annoying, it didn't mean he wanted this guy to die, but his kindness was ignored. 

"Iinuma, you coward! Let me handle all of this! You stay there and watch me!" 

Hearing Isao's words, Teshima looked at Isao contemptuously, and from his eyes, it was easy to tell that he was brimming with pride when he saw how cowardly Isao was.

Isao rolled his eyes and decided to let Teshima test whether this was really that "world" since if he was wrong, then that meant he could have a peaceful life, which was great. Nevertheless, he had to say that being kind and helpful was really hard, as one might not appreciate the kindness and help he had given.

However, as he had decided to become a good person, he would see it through. 

'You don't need to worry, Teshima-sensei. I'll take care of Hayashi-sensei for you if something happens to you.' 

Isao thought that he was kind. Teshima was about to die, so he decided to take care of Kyoko, his girlfriend, as he knew that Kyoko would be lonely without Teshima.

As Isao lamented how kind he was, Teshima was already in front of the gate, facing the madman, who had been banging the school's gate. 

"Sensei, please be careful." 

"Leave this to me, Hayashi-sensei." 

Teshima slipped his arm between the gap of the gate and grabbed the man's suit. He then pulled him forcefully, causing the man to collide violently with the gate. 

"Wait, Teshima-sensei!" Kyoko was startled and scared by how aggressive Teshima was. "Don't resort to violence..." 

Teshima smiled, showing that he was confident he could handle this, but suddenly, the man in his hand grabbed his wrist tightly and took a large bite of his flesh. 

"......"

At that moment, everything was silent before the sound of teeth biting the flesh and Teshima's painful roar echoed. 

"AAAARGGGGHHH!!!" 

Teshima clutched his arm crazily, crying in pain as a large chuck on his wrist was bitten off by the man. He fell to the ground before rolling around, panicked and unsure what to do due to the pain and blood. 

Nevertheless, everything happened so suddenly that no one could react except for Isao. 

However, Isao didn't do anything; he just observed the man who had bitten Teshima and Teshima, who had been clutching his arm in pain as he rolled on the ground pathetically. 

Still, his eyes had always been on the man who had bitten Teshima, and he saw that the man kept staring at Teshima as he kept forcing himself into the gate and even making harder force. 

'Sound, huh?' 

Moreover, probably because he gained the dog's DNA, his sense of smell became so acute that he could perceive the man's rotten meat smell so clearly. If his sense of smell was like before, even if he could smell the man's rotten meat smell, he needed to get so close to smell it. However, now, even if he was so far away, the smell was so intense that he might throw up. 

Nevertheless, he also realized that he could control the strength of his sense of smell. Moreover, he could lower it to the level of an average human and increase it to the level of a Tosa dog. 

'If I want to strengthen my sense of smell again, I need an animal with a better sense of smell, huh?' 

Or he could also get the DNA of someone with a strong sense of smell. 

However, as he wanted to know who the "man" was, he strengthened his sense of smell once again before turning his attention to Teshima. As expected, Teshima's smell slowly became similar to that of the man who had bitten him, which confirmed that as long as one was bitten, then it was game over. 

Soon, Teshima stopped crying and just lay there on the ground like he was dead. 

"......"

Everyone who was startled by what was happening also woke up due to Teshima's fall, and they stared at Teshima's body with shock and disbelief. 

"H-He's dead..." 

"No way..." 

"It was just a bite..." 

Besides Isao, there were two more teachers other than Teshima and Kyoko. 

Watching Teshima's motionless body, they thought that Teshima had died, but suddenly, his hand moved, and he also opened his eyes abruptly. 

While Isao wasn't sure why none of the teachers noticed it, Teshima's complexion became weird and pale. If he made the simplest allusion, it was like Teshima had become a zombie on the TV show. 

"Teshima-sensei, are you okay?" 

Kyoko, who saw that Teshima started to wake up, felt relief, and she approached him without knowing anything. "What a relief—" As she was about to say that, Teshima suddenly was about to grab her ample breast, then bite her, turning her into an existence like him. Unfortunately, someone pulled her, and she escaped. 

"Eh?" 

Kyoko was confused as Isao suddenly hugged her, and her body became hot as he hugged her tightly and even grabbed her ample breasts. 

"I-Iinuma-kun!" 

Naturally, she lost her calm, and she looked at him with a shy expression as a virile young man hugged her body intensely in front of her lover. 

"Be careful, Sensei!" 

Isao had promised to protect Kyoko, and this was what he should do. Still, he hoped for Kyoko to be quiet, especially the part of her butt that kept moving against his nether region. After all, he was afraid that if this continued, she might awaken the beast sleeping inside. 

However, as Teshima couldn't reach Kyoko, he reached his hand toward the other teacher, who was closer. 

The two teachers were confused and didn't know what Teshima planned to do, but as one of them was caught by Teshima, a similar scream happened once again since Teshima had bitten a large chunk of this teacher's meat. 

"ARRRRRGGGGGHHHHHH!!!" 

As he hugged Kyoko's body to save her, Isao knew everything was just the beginning.
