"Sure. I'll be relying on you," Inigo says as he moves to grab the other's hand.

After all, it's not like he quite knows how hard exactly it is to pull someone else into your world. He hasn't brought anyone into Ylisse, and he isn't planning on doing so if he can help it. Thankfully everyone seems preoccupied with their own worlds enough to ask him about it, so he's more than fine with just going along to Senku's world like this.

(Sure, it might be dangerous, going into a world where everyone has been turned into stone - but it's still preferable over leaving a friend to deal with a problem all alone.)

"I'll do my best to stick by your side, so just guide me over, if you can."
