After getting over there marriage and helping Levi and Willow everything went back to normal everybody got married and they were all fine until Natsu and Lucy say they are having a kid. Everybody is happy for them since everybody else already had kids so it was normal. Until everybody noticed that the first generation dragon slayers; Natsu, Wendy and Gageel, haven't aged at all. Everybody kept asking questions until they meet a boy with black hair and black clothing. They don't know jet but that was Natsu's brother Zeref find out what happens when they learn about all the dragon slayer's past and find out why they haven't aged. So I changed the topic of the book because I didn't have any ideas of what to do with the kids sorry if you liked the kid idea thing. So hope you like the second book I don't own anything.
