Well, and promises to help All Might fight All For One! And All Might realizes something optimistic!

"I see... so as the inheritor of One For All, I'm going to need to face All For One then?" Izuku asked Toshinori, who nodded gravely.

"Yes. I know it's a lot to take in, but..." Toshinori started, before Izuku cut him off.

"It's fine. I'll be ready," Izuku stood up, his eyes full of determination. "I know it's a lot of responsibility, but I'll face it, head on! And I know you'll be there with me, supporting and guiding me every step of the way!"

Toshinori looked at Izuku, his face full of dread he was trying to contain. He immediately thought back to the day he had parted ways with Sir Nighteye, the day his former sidekick had told him that he would face his end. He strongly considered admitting that to Izuku, to tell him that he was nearing the deadline for his predetermined end.

But then he stopped, reconsidered. Sir Nighteye had never been wrong in his predictions before, and All Might had long since come to terms with the fact that his **** was predicted... but... that was before the Lamp. Before this whole Sex Genie business. Before his injuries had been healed. Before the idea of relaying One For All back and forth had taken hold. There just was no viable way that Nighteye's Quirk could have accounted for all of this when determining his future, as the Lamp hadn't even existed in this universe at the time he had made the prediction.

In short? All Might realized that there was a very good chance that his future had already changed. He might have to bite the bullet and see Sir Nighteye again to know for sure, though he dismissed the idea for the time being. He didn't want to risk his former sidekick seeing anything related to Izuku and Momo. So instead, he simply decided to cling to the idea that his future was his to make now, and smiled broadly as he took on his muscle form before Izuku could notice the grim expression. "You're absolutely right, Young Midoriya! I'll be here for you to the very end! That is a promise I aim to keep!" he declared, patting Izuku's shoulder.

Despite how cheesy it all was, Izuku couldn't help a grin of his own, and soon left the office, his face set, prepared for the challenges to come.
