Matsuda and Motohama, his best friends, agreed with him.
From the moment they arrived at the cafeteria to eat, they witnessed how the young man was the recipient of smiles from all the women around him.
All they could do was show their jealousy and wonder why the world was so unfair.
The famous perverted trio spent the entire recess watching as these girls approached the young man and touched his arms.
Seeing the young man's thick arms and how popular he was with women, Issei wondered if he should start exercising.
The sound of the bell woke the three young people up and made them realize that they hadn't finished eating yet.
All they could do was eat as much as they could as quickly as possible before returning to their classes.
Although they were jealous of the young man, Kozue's well-built figure stopped them from having thoughts of messing with him, so they could only stay away from him.
After all, they were busy when they discovered a hole in the wall of the girls' changing room at the kendo club.
The days passed and their happy days ended when they were discovered and beaten up by the girls from the kendo club.
Although they did not give up, they kept returning to the same place and made a new hole because the previous one was covered up.
But they were soon discovered again.
The life of the perverted trio would continue in that way until they separated when a fallen angel killed Issei and was subsequently reincarnated as a demon, but his jealousy towards Kozue caused things to no longer continue in the same way.
While they were being beaten up by the girls from the kendo club, they watched in disbelief as Kozue walked between the two top beauties of Kuoh Academy.
From a distance, they could see Rias and Akeno laughing as they walked beside the young man.
Upon seeing Rias's smile, something inside Issei broke.
Issei hadn't told anyone, but he was a little bit in love with the redhead beauty.
Of course, they had never been close and he didn't think he had any chance with her.
But seeing how close Rias was to Kozue, Issei felt like he was losing something and was sad for the next few days.
Issei's condition caught the attention of his friends, and Issei had to confess his feelings for the redhead at the insistence of his two best friends.
Wanting to help their friend, Matsuda and Motohama came up with the idea of teaching Kozue a lesson so that Issei could vent his frustrations.
Normally, the perverted trio were cowards.
But Matsuda and Motohama only wanted to help their friend, and the feeling that he had lost something made Issei accept his friends' idea.
After school ended, the trio waited for Kozue to leave the school and followed him from a distance.
But it was only after an hour had passed that they saw Kozue come out.
Kozue spent a lot of time with Rias and her peerage, so many thought that Kozue was part of the occult research club.
Thinking that Kozue spent a lot of time with Rias and Akeno, Issei bit his lip in frustration and jealousy.
'Breasts' was the only thing on Issei's mind, and thinking that Kozue had the opportunity to see Rias and Akeno's enormous breasts so closely every day, made him even more excited about the idea of beating Kozue up with the help of Matsuda and Motohama.
The Trio followed Kozue, being as subtle as possible.
They didn't want Kozue to notice them and escape the beating she deserved.
After a 20-minute walk, they followed Kozue to a park and breathed a sigh of relief when they realized there were no other people in the park.
It was perfect so that there would be no witnesses.
Without thinking that anything was wrong, the trio immediately ran up and picked up the baseball bats they had gotten from somewhere and prepared to hit Kozue.
It didn't end well.
In the last second, none of them saw Kozue move and suddenly she was out of sight.
Their baseball bats continued their trajectory and the trio fell forward due to inertia.
Getting up from the ground, feeling a little sore, they saw Kozue behind them.
Without even questioning Kozue's feat of disappearing in front of them, the trio raised their baseball bats again and charged at Kozue once more.
But this time, Kozue didn't move.
Crack
Crack
Crack
With 3 consecutive blows, the baseball bats in the hands of the 3 young men were destroyed into hundreds of wood splinters.
Seeing the pieces of baseball bats that remained in their hands, the trio swallowed hard as disbelief and fear invaded their minds.
Without even a chance to back down, the three young men suddenly felt a pain in their stomachs and fell to their knees clutching their stomachs.
Coof
Coughing saliva, the perverted trio felt the oxygen leave their lungs.
As she writhed in pain, the trio looked up and fearfully stared at Kozue's face.
"They..."
None of them had the opportunity to beg for forgiveness before falling unconscious.
.
.
.
Leaving the occult research club and heading towards her home, Kozue thought about her next plans.
Although he had been in his world for several months, he still did not have enough points to become stronger or enter another world.
This was because all of their customers were normal human beings.
That's why Kozue thought of taking her shop to the territories of other factions.
As she left school, Kozue didn't notice the stares of the perverted trio because they were in a secluded place and there were many people around.
Of course, after a minute Kozue immediately knew that someone was following him and his Observation Haki allowed him to know who his pursuers were.
At first he wondered why they were following him, but his haki also noticed the baseball bats in their backpacks and he immediately knew that their intentions were not good.
Heading towards a park to be followed, Kozue used large-scale telepathy to prevent anyone from approaching the park.
The moment they realized they were alone, the trio immediately launched an attack, but were quickly subdued by Kozue.
Now with the trio at his feet, Kozue quickly checked their minds and learned of the plan to strike him.
Now that she knew what they wanted to do, Kozue wondered what she would do with the protagonist.
While he was thinking about killing Issei right here and now, he looked up and was alert in case something or someone came to save the protagonist.
But nothing happened.
Although he breathed a sigh of relief, Kozue remained vigilant as he erased the memory of the last day from the trio's minds and walked away from the place.
While Matsuda and Motohama were still on the ground, Kozue walked away with Issei in her hands and soon disappeared with a flash that produced a circle under her feet.
After Kozue disappeared, several minutes would pass before Matsuda and Motohama woke up.
And when they opened their eyes, none of them remembered the last day of their lives.
.
.
.
One hour later, Kozue was inside her dimensional shop as she stared at the green orb in her hands.
"So, what do you decide?" Kozue asked the green orb.
"Even though I got used to being locked away in the form of a Sacred Gear, I always wanted to be free again."
"Are you saying this new body will be perfect for me?"
From the green orb in Kozue's hands, a draconic voice emerged, inquiring about Kozue's offer.
"Yes, and although your new body will be that of a baby dragon, you will regain all your strength over time or by eating," Kozue replied.
"It doesn't matter, as long as you're not lying to me, I'll accept the contract," the voice replied.
"Then I'll start right now," Kozue said, and several magic circles appeared in front of him.
In the middle of the room and surrounded by magic circles, a drop of blood appeared and soon began to transform.
Little by little, the drop of blood began to grow and take the shape of a small dragon.
During the process, the green orb in Kozue's hands flew towards the forming dragon and they merged.
After a minute, a small red dragon appeared.
"Hahaha, I, Ddraig, am free and that stupid Blanco is still trapped."
When he opened his eyes, the little dragon let out a joyful laugh as he mocked his rival, the white dragon.
Ddraig could already imagine flying around the world again without restrictions, with fearful looks from all beings on the ground.
But because of its current size, it was an adorable image.
Of course, nobody would think that this little dragon was Ddraig the Welsh dragon.
