OnePiece| Killers Connection with Wano Kuni

As we already know Killer is one of the 12 members of Worst Generation and also the Vice Captain of Kid Pirates. Killer has also been shown as a Swordsman just like Zoro who is also a Vice Captain of Strawhat Pirates. Being a Part of Supernova or Worst Generation means that he must be having a very important role in the OnePiece Story. Zoro and Killer both have similar characteristics like they both are a swordsman, they both use a unique style of swordsmanship and they both are Vice Captains. I think killer will play a huge role in the Wono Kuni arc. I am also among those people who thinks that killer has some connection with wano kuni. Although he has been shown many times in the onepiece storyline we still dont know anything about the Kid pirates including both the captain and vice captain of the kid pirates. When we were shown Eustass Kid beaten up and imprisoned in the cell we didn't see killer and his crew inside the cell as well. I believe that kid was the only guy who got beaten up, as we have already seen that kid is always angry and he cant control his anger when he gets angry maybe that might be the reason why kid is beaten up now. Maybe kid might have tried attacking kaido when their base got destroyed by kaido and he got beaten up very badly. Killer not being inside the cell with Kid is another reason why I am supecious of Killer's Identity. Not only that one particcular reason but another reason being killers unique fighting style that even Zoro was surprised of and he even complimented him.
Wano Kuni is known as the land of Samurai's and we all know that samurai are excellent swordsman. Oda also gave us a hint to Ninja when he introduced Raizo in the story line. This also gives us information that not only samurai's but there maybe presence of ninja's in wano kuni arc. I dont know if Oda introduced ninja just for a comedic gag or he was serious but we can always expect the unexpected from the genius creator of onepiece. As Wano kuni is famous for samurai and its swordsmanship we can already tell that we will be excited as well as surprised when we enter the wano arc. Brook even mentioned that Wano has some extremely powerful samurai and we also got some glimpse when kinemon and  Ryuma showed us their fighting style. Brook also mentioned that wano kuni is an isolated nation that never lets outsiders enter and doesn't even have ties with the world government. He mentioned that swordsman so called samurai's are so strong that even Navy wouldn't approach them. Just by this statement alone we can just imagine how strong they are. I think that Kaido is also a samurai from Wano just based on his appearance and his personality like his beard, mustache and his dressup. If kaido is also from wano and now he is ruling over wano it just gives us a hint to the power of Kaido and wano in general. Kinemon also gave us a hint that wano has samurai's using different fighting style and are very powerful so this is another reason why i think killer is connected to wano kuni. Maybe the reason why killer was not shown locked inside the cell with Kid was because he is safe as kaido immediately recognized killer as he has some connection to Wano.
To let you guys know, I am just predicting that this might be the real situation based on some facts shown inside the onepiece story line and what i was thinking. Please do let me know if you agree with me or not by commenting on it and can also express your point of view on the comment section.
