He goes with Mirko!

"Hmm, you've got a lot of good picks," Toshinori noted as he and Izuku looked over the internship offers. Momo was also present, stating she wanted to put in her own advice for Izuku, and with some bemusement, not sure what advice she would offer, allowed it. "Honestly though, I was thinking about calling in a favor and asking my old mentor, Gran Torino to teach you a thing or two..." Izuku noticed that Toshinori shivered unconsciously as he said it. "Though he's a bit... Intense. I'd offer you one myself, however, we already had two people ask at some point or another if you were my secret love child or something."

Izuku chuckled at that, having already told All Might about Todoroki asking him that. Leaving out the personal details of Todoroki's life of course. "Alright, yeah, I see his name on the list..."

"Master, if I may?" Momo asked, wrapping an arm around his shoulders. "If this guy was All Might's mentor, he could probably get him to train you any old time. But these internships would offer unique experience with different Heroes you probably won't get second opportunities with. So perhaps shelve Gran Torino for now and potentially revisit training from him if you need it later and pick someone else you might learn something from for now?

Izuku blinked and exchanged a glance with Toshinori, who sheepishly nodded, conceding her point. "Well... Alright then... It should probably still be someone who fights physically though, someone I might pick up a few moves from..."

"I got someone on the list in mind already!" Momo chirped, pointing.

Izuku looked at the list, and then back at Momo, slightly deadpan. "...you just picked the most suitable attractive woman, didn't you?"

"...it was a factor, but I genuinely think Mirko would be a good fit for you!" Momo chirped. "And if you actually manage to hit it off with her, that's a bonus!" She then grinned. "Besides, think about it! Bunny girl!"

"...argh, you got me there," Izuku sighed, making the decision. "If only partly to say I let my girls have some input," he added.

Toshinori sweat dropped. "I think she has more than "some" input. Hopefully, she's not too bad of an influence on Young Midoriya," he thought.

...

Meanwhile, Bakugo made his own decision on the hallway, based on who was the highest ranking Hero on his own list. Learn from the best to be the best and all of that, and the influence of that Hero might somewhat counter the bullshit Endeavor spread. He was slightly disappointed that no one in the top five gave him an offer, but number six wasn't too bad he supposed. Plus, he kind of liked the attitude of the Pro in question. "Mirko it is," he said to himself.
