If you age them up so they aren't kids this game would rule! I think Kilua would be hot when he grows up based on other silver and white hair anime characters. Not sure if it matters but I just thought I'd share my opinion haha.
Hunter x Love
A downloadable game
All Characters and images(until updated) belong to rightful owners. Gon and Killua fall in love that's if you get it right. Right now there is only one thing to do. More shall come!!!!!
