riku/roxas is a huge favorite of mine, and that's my ideal relationship to play between them! i'd be absolutely down. i've had a lot of fun playing that kind of relationship in AU's or in canon! i'd love to try these two out first if you're interested, and we can definitely roll into sora/namine and sora/riku later on if you're interested! (i also have a ventus muse and i can definitely dust off vanitas.)

oh boy... good luck! have fun dying like the rest of us... i'll dm you since i have an idea for riku and roxas based off of those spoilers. i'll also drop a few meme links on you and see if those sound appealing.
