Either restart or remove and re-insert the game card. Kebuju and encountering him on GTS results in a complete freezing of your game. TL DR: There is a new hacker on the GTS by the name of Japan. Trading Pokemon is, without a doubt, one of the best features in the games and hackers are ruining it for everyone. Hopefully GameFreak makes trading more protected and fun. However, he isn't that big of a menace in Wonder Trading because Gen 7 Wonder Trade is still very active and you need quite a bit of luck to encounter the person. I had to restart the game but the trade was complete ( received a hacked Shiny Alakazam). I was Wonder Trading yesterday but I unfortunately encountered the person. Kebuju also Wonder Trades, so you're sorta done in that respect as well. The only means of trading on GTS now is depositing your Pokemon and patiently waiting for the desired Pokemon to arrive. Another disadvantage is that those with bad internet connectivity will have to suffer more as you get disconnected if you exit the game and need to connect to the GTS to access it. This also means that if you have deposited a Pokemon quite some time ago, you need to withdraw and send it again for better visibility. This means that you'll arrive at his/her Pokemon soon and would not be able to search further, limiting your possibility of getting the desired Pokemon. This hacker has come only recently and recent Pokemon come up on the front of the GTS. What's worse and how is he/she any different than other GTS hackers? Well, if you search a Pokemon in the GTS and if incidentally you stumble upon this person's hacked mons, the game freezes and you can do nothing except removing the game card or turning off the power and then restarting your 3DS. Now, to make matters worse, there is another hacker by the name of Japan. Some other legit players make unfair trade requests (like Yungoos for Kyogre). Trying to trade with them resulted in a temporary soft trade ban. What started out as a Pokemon Fire Red ROM hack on 4chan has since exploded into Pokemon Clover, a game that many believe to. The GTS is filled with hackers like AdventrSnivy who give out hacked shinies that cannot be traded. Wonder Trades are (mostly) either some really useless stuff or hacked shiny mons. Generation 7 trading situation couldn't get any worse off than this.
