The storyline is getting very interesting in that something she set just for fun about her age had a very real effect on the world. This is something I have never seen done before. The closest is making lore about themselves if they are making themselves very old, but they know what they did since they made it themselves.

A Yugioh fanfic? Reads.... hmmmm this is pretty good. I been wanting to read a good Yugioh fanfic, but couldn't find one or maybe I'm just bad at looking.

Maybe it was meant to be 55 feet long? IDK why, but so many people seem to mix up height and length like pokemon, for example. Wailord has a height of about 47 feet, yet many people say it's 47 feet long, making it way smaller than it should be.

This is surprisingly good. I had seen other The Last Air Bender fanfic, but none of them had ever caught my interest like this one, which makes me wonder if I had missed some good The Last Air Bander fanfic.

Would his lie about himself once being possess by a dragon sprit end up becoming true? Like the system giving him one to idk... make him like a second avatar?

You would think if people hate someone, they would try to stay away from that someone, but actively looking for that someone just so you can hate on them is just degenerate. Most likely what they "hate" is that Masashi Kishimoto hinted at Sakura's potential to be a great character during the story, but in the end, did nothing with her. The story to me has been good so far. I'm too lazy to write a complete reason as to why other than I like the main character so far, plus some of the abilities this Sakura has is what the original Sakura should have been able to do, but was thrown away or never mention again
