After the events of League of Legends True Damage skin lineup last year, I was inspired to come up with my own music skin line with Nami being one of the four members of the group. And that group would also consist of Karma, Neeko and Lux. The idea would be that the group would be a girl group centred around pop music and this group was formed with the intention of them all using the voices they had to stand up for what was right, Nami's focus being the ocean. They also share the same universe as the other music skins, K/DA and True Damage.
I plan on getting the other three skins done over the next few months, so expect more soon.
