[This guy is such a big grouch, wow. Tanjiro can't help but laugh softly at his grudging admission that it's helpful, and then again when Than's dragon proceeds to aggressively claim him.]

Well, I don't mind, so it lets you get back to whatever it may have been hassling you out of doing? Oh-- [Setting his good hand carefully against the dragon so it doesn't tumble off his shoulder, he bows forward.] I'm Tanjiro, by the way. [He doesn't specifically ask for Thanatos' name, but the implication is there anyway.]
