She would probably move to Germany if she were to leave Karakura (though i doubt that'll happen tho LOL), finishing her college and expanding her business more. Creating her own yakuza (or in the more European term, a mafia) as to rebuilt what her older brother Sakuta's goals were before he died, and probably would try to establish herself as someone powerful while also keeping her true identity unknown. Would also probably still visit Karakura once awhile, seeing how its doing and basically visiting friends and family.

As of now, Venti icly is trying to finish his degree in Arts at Switzerland, though I do plan for him to go back to Karakura someday as a arts teacher. But if that happens and he decides to quit, I would see him traveling around the world, perhaps with a partner or single traveling depending on how his relationships would go. He doesn't really have that big of a goal besides being satisfied with what he has, would settle somewhere back in his home country Germany if he decides to marry someone and would still visit Karakura from time to time.

Once he quits his job as lawyer in Karakura, he would probably go back to China to teach again as a history teacher. He was a teacher before he took up law, so he has some experience so he would settle down somewhere in China while keeping in contact with his two cousins. Would rarely visit Karakura, though would only do so if its a special occasion, or for his best friend Koyuki.

100% would go back to Tokyo to continue her modeling career- she was a aspiring model in Tokyo before she moved to Karakura to follow her two cousins. Would never return to Karakura unlike the others, preferring to keep her history in the town a secret as she probably would finish college in Tokyo instead.

If she were to quit her position as Reporter and move away from Karakura, she would probably travel around the world as a blogger, recording and writing down her experiences and knowledge she learns from traveling. Would settle down back in China if she finds a partner, living a quiet life while still continuing her blogs. Though would probably never visit Karakura again due to it reminding her of her dead cousin, not wanting to remember her yakuza days.

Would 100% move back to the Philippines once she finish college, taking masters on her home country to further her education. Would take up a reporting or law position in the future, wanting to help others and better her home country. Would maybe still visit Karakura, though rarely since she prefers to stay in her home country much more than traveling to other places.
