Four whole days had passed and during that period, Kisuke didn't leave his room. Trying to predict the future on a scale he hasn't done before, writing up various blueprints that may help him, and calculating the theoretical framework of the 'World-Tying Rite', he'd ended up over-drafting himself for the first time, 'I'm tired...' He finally admitted.
He wished he could feel and snuggle in the warmth of those in the other world, 'But even after all of this, I still can't see the chance of winning.'
Even though Chimune Chipaoti promised Issei a way to fight the malevolent Evie Gods by finding the chosen Heavenly Breasts, Kisuke couldn't honestly depend on something as vague as that. In the first place, he doesn't have enough information to trust anything that Issei told him and those malevolent Gods might just be posing as this 'Chimune Chipaoti'. Unless he could gain more concrete information, he couldn't take anything they said more than a proof of their existence, 'Heck, they may have already controlled Issei and I just can't detect it.'
As such, he came to a conclusion where he would have a relatively good chance of at least gathering the much-needed information, "Another 'route'. Instead of waiting for their arrival, I have to open another way towards them and the only way I can do that is to open the path from another dimension."
However, that plan opens more problems that had to be solved first, "I have to get the cooperation of the one guarding that dimension and that looks like an impossible case."
And even if he was able to gather enough information, if a fight broke out, he highly doubted his tricks would work, "The only ways he could think of to have matching firepower is to nurture talents or recruit. The first one is the safest but takes a very long time and might fail... So a 'boy band' of my own, huh..."
Kisuke closed his eyes and contemplated his options for one last time. When he opened them again, a sharp glint was present within them, 'Oh Kisuke... All this time, you've been on the passive side. It's time to get aggressive.'
After clearing all the holographic screens that have been floating all around the room, Kisuke activated the communication formation under his desk and it didn't take too long for him to be connected to the otherworld.
[Kisuke-kun? Is that you?] The one who answered was Hestia.
"Hi there, Hestia-sama~! How are you doing?"
The two of them talked for a while and Hestia told him that there is no one else in the tower right now because they were having fun outside.
"Why aren't you with them?", asked Kisuke with visible concern.
But Hestia just laughed at his reaction and said, "Don't worry. I'll join them soon. I'm only joining later because I met with an old friend."
"I see. So Medusa has already returned?"
"Yep~ She's as energetic as ever."
"That's good to hear." Kisuke nodded in satisfaction and relief, "I'm sorry, Hestia-sama, but I'm about to call back Yoruichi and want to talk to her alone."
Hestia stood up from her seat, "Alright. I'll prepare to go out." It was then that Hestia's tone became serious, "Be careful. I can tell that you've decided on something big."
Kisuke laughed awkwardly and scratched his head, "As expected of Hestia-sama. It's really hard to hide things from you."
Hestia proudly stood up and placed her hands on her hips while spreading out her elbows, "Of course! You're my child, after all!", but before continuing, her prideful tone disappeared and was replaced by a gentle one, "Don't forget that you can depend on me more. If it comes down to it, I'll bring myself to the Lower World and if it's protecting people, you can leave it to me."
Kisuke was speechless for a moment before smiling wryly, "I hope I could say that it wouldn't get to that point, but I'd be lying to you."
"I'm happy that you're being honest since I can't really tell if you're lying. Just keep in mind what I've said." Hestia left the room, but not before reassuring Kisuke that he'll still have her support even if things go awry.
A few minutes later, Yoruichi arrived and her first words were, "Change of plans?"
"Yeah. I'd like you to make some additional changes to the barriers and add a few more. I'll be sending the instructions to your terminal later. After that, I'd like you to get Loki and Freya's permission to bring their children to deep-level floors and push their excelia to the limits while also teaching some useful things. Bring Serafall with you."
"Just Loki's and Freya's?"
Kisuke thought about it for a second before adding, "Include Hermes' children, some of Hephaestus' and Ganesha's children, Bell Cranel's party and everyone from the Hostess of Fertility."
"...You want to push the schedule ahead that much?"
Kisuke nodded, "Yes. Once they're ready, look for the chance to trigger the 'Apocalypse'."
Yoruichi frowned and replied, "But we'll only have a few Gods on our side by then. I don't think that's enough to deal with Chaos. To begin with, do we really have to antagonize him? All we need to do is lay low and he won't do anything to us until we have a way to leave this place entirely."
"If you're worried about our moral standpoint, please don't. The last time I crossed the void, I concluded that he couldn't be trusted and we're essentially saving this world from him."
"...We are no heroes, you know that."
"I know, but this world's cooperation is essential and I'm willing to take the stage. Besides, something nice came up from this world and I think it'll be a big help."
Yoruichi's eyebrows furrowed and became confused about why Kisuke was taking such an aggressive stance, "These instructions, they aren't for fighting Chaos. What are these for, ultimately?"
Kisuke took a deep breath and said, "Fishing up the owner of the Dungeon and killing it."
"...That is even more confusing."
