Probably unsurprisingly, Toge is a pretty quiet companion to walk with. When he wants to point something out, he points and says- "Tuna, tuna."

There's a method to his madness, and it's not that hard to pick up once people know that. They have to take the train and he uses his spoon, demonstrating how to do it.

The apartment buildings themselves are tall and he gestures to it. "Tuna mayo." This is the building. There's a nice main entrance, but Toge makes a beckoning motion and goes around the side of the building.
