"Of course I am!" Izuku's reply comes quickly. "I love hearing everyone's stories and learning the differences between all our worlds... it's really great!"

It stands to reason that Tonbokiri would be curious in return, and Izuku just nods eagerly.

"Yeah, that's right. Quirks are so common nowadays, more heroes are needed to combat the villains with quirks. Besides, the government needed a way to safely regulate quirk-use, and having people register as heroes was the most efficient way to do it," Izuku says, somehow managing to get all of that in one breath. It's obvious that he loves explaining all of this.
