[Well, that excitement and leaping around as soon as he mentions the name is answer enough for Ren, but it is nice to get the confirmation once she recovers herself. It only reinforces to him, too, that it was the right decision to coax that name out of her. For her to have been so excited the whole way through, and jubilant to be recognised...how long has it been, he wonders, since she'd had that opportunity? Since anyone had stopped to ask her name or even considered that it might be of significance to her?

While Ren may not be the type to prostrate himself before a god - he's dealt with far too many nasty god-tier powers before to be cowed by that sort of thing - he's polite by nature. So he briefly puts a hand to his chest and gives as much of a formal bow as he can while sitting down, enough to show that he's honoured without having to be excessive.]

Well then, it's truly a pleasure to meet you, Amaterasu-san. [He offers out a hand again, in case she wants to temper her excitement with some more affection.] I hope we can be friends, even though we're far from home.
