Oshima is a significant island for Japan and was also crucial for GHQ. After all, on that island, there was a secret GHQ area disguised as a sanctuary.
Within this secret area, something extremely important was kept. However, due to this, the area was well-protected by an electronic security system far superior to other bases. Even Leucocyte didn't have such a complex security system.
Gai was aware of this, which is why he needed Souta's Void, capable of opening anything. Therefore, Gai made several preparations to invade this secret base.
As Undertaker moved to recover the rock that started all this...

In a location in Oshima, Shu now stared at a tombstone.
"I've come, Father."
Sadness was visible on Shu's face as he looked at his father's tombstone.
Korosu Ouma.
This was the name engraved on the tombstone, Shu Ouma's father.
Recalling various things from the past, Shu sighed. His family used to live in this place, but despite living here for ten years, he didn't remember much about his father.
"Kurosu, it's been a while... huh?"
While Shu looked at the tombstone, he heard a voice seemingly from nowhere.
Turning his gaze, Shu looked at a blond-haired teenager with sky-blue eyes, dressed in a long white coat. The young man was smiling, simultaneously gazing at the tombstone.
Narrowing his eyes slightly, the young man spoke to a surprised Shu.
"You must be Shu Ouma, Kurosu Ouma's son."
"Who are you?"
Surprised by his words, Shu blinked. He had never seen this person before, but the teenager seemed to know him.
Glancing at him for a moment, the teenager smiled.
"My name is Yuu, an old friend of your father."
"My father?"
"Yes, Scientist Kurosu was quite famous. His discovery of the Void Genome and the Apocalypse Virus, as well as the vaccines developed today, all credit to him."
Answering his question, Yuu slowly approached Shu, who was now surprised by what he heard.
"Really? My father was famous?"
"I'm surprised you didn't know."
"Sorry... we didn't talk much at home."
Embarrassedly scratching his head, Shu smiled bitterly.
As he said, even though his father was a famous scientist, Shu didn't remember much about him, or rather, he didn't want to remember.
After all, coming to this place brought back very nostalgic feelings.
"I understand. But you know, your father left you a little gift."
"Gift?"
Tilting his head in confusion, Shu looked at Yuu, who now took a small glass cylinder from his white coat.
"Yes, Kurosu was a good father. Although it's unfortunate he couldn't give it to you in person, I can still give it to you as his final wish."
Looking amused at Shu, Yuu handed him the small glass cylinder.
"This..."
Shu didn't know what to say. The fact that he didn't know much about his father was something Shu felt a bit ashamed of. Now, this young man was giving him a gift from his father, making Shu have many doubts. Still, he was also a bit curious. After all, even though Shu didn't know much about his father, he knew he was Haruka's professor.
"Don't worry; this little gift was meant to be in your hands. I hope you use it; your father would be very pleased."
With a smile on his face, Yuu looked into Shu's eyes before Shu's eyes lost their light.
"Yes, he'll be very happy."
Taking the cylinder, Shu didn't hesitate to inject its content into his body.
This caused a small symbol to start forming on the back of his hand.
Yuu's eyes lit up as he saw this.
"Hehe, are you happy, Eva? This is your beloved Adam, after all."
[Shu! ...]
With a smile on his face, Yuu now looked into Shu's lifeless eyes, while at the same time, he heard Eva's excited voice.
"Your little Adam has quite the potential. I just hope he has what it takes to defeat Yuki Uchiha."
Shaking his head, Yuu was very disappointed. Yuki was the best specimen, the perfect Adam. His body was powerful enough to resist the Apocalypse Virus, and once he joined with Eva, he would have a perfect body, making him more powerful.
"I have high hopes for this. I hope you can dethrone the King from his throne... Shu Ouma."
Leaving these words, Yuu's body transformed, turning into small silver lines before disappearing.
"Eh? What happened? Ouch... It hurts."
Regaining the light in his eyes, Shu looked at the cylinder in his hand before clutching his arm in pain.
His little trance had ended, so he was now confused. Turning his head, trying to find the young blonde man, no matter how much he searched, the young man was nowhere to be found.
"Weird... huh?"
Scratching his cheek over this, Shu looked at the glass cylinder, now empty in his hands, and scratched his cheek. However, in doing so, he could see a mark on the back of his hand.
"A tattoo?! What?! How?! When?!"
Staring at the mark on his right hand, Shu panicked. He didn't know when or why he had a tattoo on the back of his hand, but he knew it would be very troublesome. So, he tried to get rid of it by scratching, washing, etc.
But no matter what he did, the mark on the back of his hand didn't disappear.
"It can't be... I just came to see Dad."
Sighing at his bad luck, Shu shook his head.
This surely was his unlucky day, meeting a young man who was a friend of his father, who disappeared like magic, at the same time this strange tattoo appeared on his hand.
"I must be more careful from now on... There are many suspicious people these days."
Thinking about this, Shu looked at the glass cylinder in his hand before getting rid of it. Shu didn't know what purpose or use that thing had, but it surely meant trouble. Nodding to himself, Shu decided not to think too much about it. However, Shu ignored something important; the glass cylinder was empty. The sudden pain in his arm and that this cylinder looked like a vaccine—these small details are something he'll regret later.
But none of this mattered to him, so he returned to the mansion.
