Why does Seven call himself 707? Well, that's what I'll be talking about in today's blog post. While playing Mystic Messenger, you can see Seven referred to as Seven or 707 many times. But why did he choose that specific alias? Well, some people think that it's because of the error code 707, and other people think it's because 707 is LOL upside down. Although both of these would make sense, it's hard to tell if one or both of these reasons are actually true. It could be for a lot of different reasons as well. But since he works with computers a lot, the error code theory would make sense. But because he uses the term LOL a lot while he's in the chatroom, that would also make sense. But, it could also be because the number 7 is supposed to be lucky. However, this one is doubtful since he doesn't like that nickname. The reason he chose that specific nickname is a mystery to all of us MCs. Until we get some confirmation on the reason he chose this name by Cheritz, there's no way we could tell why he chose it. But, this is mostly just my opinion anyways. I hope you guys still like this post though! As a little bonus, I will include a picture of Seven down below. Enjoy!
