The next day arrived, and Asuna informed everyone that she wouldn't be participating. She then went off with Ren Isana for some special training.
Sora and the others were a bit puzzled, but they didn't say much. If Asuna wasn't joining, they could just go themselves. However, Utaha Kasumigaoka felt quite disappointed that Ren Isana wasn't participating.
After sending everyone off to the No. 3 Dimensional Rift, Ren Isana returned to the school with Asuna. He began her special training, teaching her several [Water Magic] and [Wind Element Manipulation] spells.
With just Ren Isana and Asuna in the dorm, they didn't even need to set up a [Silence Magic] barrier. They spent their days training diligently on the ground floor.
Days slipped by. While training Asuna one day, Ren Isana suddenly sensed the descent of the World Will, forcing him to halt.
"Do you want to travel through time?" The World Will's voice sounded somewhat weak, as if she had just endured a massive battle. A flash of surprise crossed Ren Isana's eyes. *Did she suffer a loss in her fight against Alaya and Gaia?*
"Is there a new world you want me to visit?" Traveling through time... it certainly wouldn't be the timeline of this world. As the World Will, she would never allow anyone to tamper with this world's history.
"Exactly. A new world has recently connected with ours. I've reached an agreement with the god of that realm. You need to go there to change a few things and place my power at the moment of her birth," the World Will's voice echoed again, explaining the mission.
Hearing the details, Ren Isana was astonished. She wanted him to go to another world and change history? And this was an agreement made with another god?
"Uh... that sounds incredibly dangerous. What if I can't win?" Ren Isana was a bit bewildered. Anyone capable of making a deal with the World Will had to be an absolute powerhouse. Was it really okay to send a small fry like him?
Though his strength had reached Tier 7, he felt like he'd still be insignificant in the eyes of true masters. Thus, he couldn't help but feel a little anxious.
Beside him, Asuna listened intently to the conversation between Ren Isana and the World Will. This was her first time actually sensing its presence. Hearing the stakes involved, she also grew tense.
"No problem. Rest assured, no harm will come to you. Besides, the ending of that world is already fixed. As long as she is born in the end, everything else can be altered however you wish. Any changes you make will be brought into the future instantly," the World Will explained.
Ren Isana finally breathed a sigh of relief. If that was the case, there shouldn't be much of an issue. It was best as long as he stayed safe. Moreover, the rewards from such an absurd world were bound to be immense. Thinking of this, he asked, "How should I address you?"
"Pandora... or you could call me Heaven's Way... let me think..." The World Will slowly listed off her names. Ren Isana was stunned when he heard them. *Pandora? Heaven's Way?*
There were quite a lot of names. At the same time, Ren Isana understood—she had likely assimilated her counterparts from other worlds, which was why she possessed such a strong human personality!
"Then I'll call you Pandora!" In all likelihood, the Pandora from the God Slayer world was also her. Because they had merged, the mechanic where killing a Heretic God granted [Excelia] must have been established. It all made sense now!
"As you wish. So, do you accept? If so, I will send you there now." Pandora didn't seem to care about the name, focusing entirely on the task.
"Let me pack my things first, then you can send me. I need to make some arrangements. By the way, did you win the battle against Alaya and Gaia?" Ren Isana asked for some time and took the chance to satisfy his curiosity.
Mentioning this caused Pandora's mood to visibly brighten. She spoke with immense pride, "Let me tell you, those two are currently hiding in the Root crying! I even shattered the Throne of Heroes, and their Heroic Spirits have all escaped!"
She was truly formidable. *How dare they act out? Do they think I'm easy to bully? They even dared to touch the cub I sent over! Do they think my fists aren't hard enough?*
If the Root of that side hadn't been so terrifying, she would have gained two more names by now. Although she paid a small price, it was worth it. Once she rested, she would become even stronger!
And if Ren Isana successfully completed this task, the benefits she would reap would be enormous. It was a win-win situation.
As for why she specifically sought out Ren Isana? It was because he was special. That world also didn't permit Tier 8 entities to enter. Since Ren Isana was only Tier 7, throwing him in would allow him to grow rapidly.
He was strong enough to handle everything there, and his power level would surely skyrocket. Reaching Tier 8 or even Tier 9 would be no problem. He was the perfect candidate.
"Impressive. Knowing that, I'm relieved. I'll prepare now and contact you shortly. The power I just obtained includes a way to communicate with you, so please don't block me." Ren Isana gave her a thumbs up.
Hearing this, Pandora quickly vanished. She knew exactly what power Ren Isana was talking about—[Marble Phantasm], the ability to communicate with the world and manifest reality.
Though she had rejected Arcueid's access, she wouldn't reject Ren Isana. This meant he could use [Marble Phantasm] to speak with her whenever he wanted.
Once Pandora left, Asuna finally spoke up. "Whoa... is that really our World Will? Isn't that just way too ridiculous!?"
This was the supreme existence of their world, yet Ren Isana could talk to her at any time, and she seemed surprisingly easy to get along with. It was simply unbelievable.
"Yeah. And she's probably moonlighting as the will of many other worlds too. You can tell from the names she mentioned." Ren Isana couldn't help but sigh.
As those worlds connected to this one, the low-level ones were likely occupied and consumed by her as nourishment to grow stronger. After all, not every world had its own World Will.
If a world had a World Will, like the Type-Moon universe, she would coexist with it. But if its will was weak, it would simply become her fuel.
Currently, it seemed the World Will was on the side of humanity and was quite close to the higher-ups. Otherwise, she wouldn't have this kind of attitude.
"It looks like I can't keep training with you." Ren Isana pulled his thoughts back and looked at Asuna. This mission was one only he could take; there was no way he could bring her along.
Asuna didn't mind. She said seriously, "Just be careful. If anything goes wrong, just run for it. Once Yukino returns, I'll go meet up with Sora and the others!"
As she spoke, Asuna stepped forward to straighten his clothes and gave him a kiss, just like a newlywed wife sending her beloved husband on a long journey.
Ren Isana nodded and kissed her back before heading off to pack. He already had plenty of supplies on hand. Though he didn't know what kind of world it was, bringing plenty of food and water was a safe bet.
*And traveling through time... will I be going back to ancient times? Or some extremely dangerous battlefield? I wonder how far back the jump is!*
He finished packing quickly, waved goodbye to Asuna, and then contacted the World Will. In the next instant, he vanished from the room.
Watching him leave, Asuna waved her hand, her mood suddenly dipping. She felt Ren Isana's strength was growing faster and faster; if this continued, she might never catch up.
With a sigh, she silently left Ren Isana's room. After closing the door, she took out her phone to check where the returning students were.
Some students couldn't sit still after just a few days at home and insisted on participating in the god-slaying mission. Many were rushing back to school, including Yukino. Once she arrived, the two of them would head to the No. 3 Dimensional Rift together.
Meanwhile, Ren Isana was brought into a void of nothingness. Sensing his surroundings, he felt a sense of amazement. The space around him was incredibly chaotic, making it impossible to tell up from down or left from right.
If not for his powerful [Spatial Perception], the sheer disorientation of this place would have made him faint instantly. Even so, he felt a throbbing pressure in his head.
"I'm sending you over now. That world hasn't fully connected with ours yet, but she has already contacted me!" Pandora's voice rang in his ears.
Ren Isana nodded, letting her handle the arrangements. He was here to be a tool, and hopefully, reap some rewards. He just hoped he'd get some good loot this time!
Exploring a new world meant a wealth of rare items. Ren Isana wasn't about to refuse. As for whether she would harm him? The idea was laughable. If she wanted to do something to him, she wouldn't need to go through all this trouble.
As he nodded, he felt himself begin to move. A surge of power appeared before him, merging into his chest and entering his heart space directly.
Ren Isana wasn't surprised. She likely knew all his secrets, including the fact that he came from another world. Nothing in this world could be hidden from her.
Without a system to mask him and with such heaven-defying talent, it would be weirder if she hadn't noticed.
Ren Isana sensed the power entering his heart space. It felt like the aura of the World Will itself—a sort of seed?
Even Beatrice was drawn to this power. Beatrice, who had been a shut-in inside his heart space, looked at the suddenly appearing power with confusion. "What is this? Why is it so terrifying!?"
