"This is something we have to do whether it's Plan A or Plan B" All Might says as he places two magnets on the whiteboard, one with All For One's smile and one with Tomura's hand, "we have to split them up! Based on the data from the fight with Star and Stripe, Tomura Shigaraki is currently much more powerful than All For One. As for All For One, those of you who saw the battle at Camino should already know how strong he is. Plus, in addition to their contact using radio waves, there's the shared consciousness they showed us in the attack on Tartarus, but we don't know how much they actually share yet. So if they come at us together, we cannot win".

"Then, why didn't they use that against Star?" one of the military personnel from America asks as he holds his hands out to the side.

"He was probably trying to avoid her calling his name" All Might says as he looks at the man, "since with New Order's rules, saying "All For One" would probably have worked. For this second decisive battle, we should keep them at least ten kilometres apart. That's the minimum prerequisite for us to win".

"Of course, the other side will be moving their pieces so that doesn't happen" Tsucauchi says as he looks at All Might.

"That's exactly right, Tsucauchi-kun" All Might says as he puts a Touya magnet onto the whiteboard, "the fearsome fire that spread and burned everything up. The threat we clearly experienced at the training camp and the mountain villa. Just having Touya Todoroki in the vanguard will stop us in our tracks".

"So then, in order to stop All For One and Tomura Shigaraki, we have to separate Touya Todoroki-" Ragdoll says as she steps forward.

"Not just Touya Todoroki" Sansa says as he looks forward.

"Right. Everyone" All Might says with a nod, "we need to separate the enemy's main forces and crush each and every one of them. In order to do that, we need to lure out the enemy! First, we need to use Young Shinso's Brainwashing to make Young Aoyama and his family act and draw the enemy out without them noticing. Then, we'll use System Troy to split them up. After that, Young Monama, who has used Copy to get Kurogiri's Warp will transport the villains to the places we want them. We need five locations for splitting them up. We will transport the greatest villain, Tomura Shigaraki, to the U.A. coffin in the sky, which is able to deal with his Decay. Then we'll have Young Monama copy Aizawa-kun's Erasure to prevent Shigaraki from using his Quirk. The offence will centre around Young Midoriya and including high-ranking heroes like Best Jeanist, Edgeshot, and Mirko. In the same way, we will transport All For One's body to Gunga Villa, and send out a team formed around Koko, with the top two heroes, Endeavour and Hawks to deal with him. We will transport the madman, Dabi, to Camino Ward Ground Zero. We will send a team with Young Todoroki and Endeavour's sidekick, with their ability to deal with fire, at the centre. Because it's hard to predict what Himiko Toga will do, we'll isolate her on the outlying island, Okuto Island, and form a team around Gang Orca, with Young Uraraka and Young Asui joining him, since they have experience fighting Himiko Toga. The remaining villains will be transported to Takoba Nation Stadium. For those villains we were unable to split up, we'll continue to use System Troy and attack with the remaining hero teams. Moreover, there's a strong chance that Gigantomachia, held at the site of Jaku Hospital, and Kurogiri, at Central Hospital, will be next on All For One's list to recover after Shigaraki's re-emergence, so we've posted people at each of those places, too. We will carry out the operation in parallel at each of these eight locations. This is the plan that Tsucauchi, Aizawa-kun, Young Kokoro, and I came up with for this second decisive battle!".

All of the heroes gasp as Tomura picks up his arm, the fingers growing more and more as his arm becomes larger and longer.
