Looks like it’s a double debut in this match folks! It’s particularly surprising that Natsu hadn’t appeared until now, but better late than never. Both of these fighters use the fire element to their advantage. Natsume does have some mastery over fire and is regarded as a dangerous fighter, but he’s not going to be able to defeat Natsu. Natsu has been in many insanely difficult fights over the last few years and he continues to get stronger and stronger. I would certainly consider him to be around Naruto-Tsuna level in battle strength, which is no small feat. I don’t think that Natsume would be able to keep up with his speed and Natsu’s sheer power will ensure that only a few direct hits are necessary. He claims victory in this battle of flames. Natsu wins.
