Hello! From what I can see, I believe your preferences go really well with Miracle Country! It's a CLAMP based game, so any of your muses from Cardcaptor Sakura would be a great fit! We have a Sakura in game who really misses her friends and family.

Gon and Killua would also be a nice fit for the game, I believe. Miracle Country is a small world and the people brought to it are tasked with finding a balance of good and bad energy that affects all of the worlds. So their actions in canon and what they do in the game can have a positive or negative even on the game and what events happen.

Let me know if you have any questions! Thank you!
