>>8731894Decided to cross reference this with the Wiki. Each color represents a year.
>2010 (red) - 1 model, 10 shells>2011 (orange) - +1 model, +11 shells (including 4 for Nano V1)>2017 (yellow) - +2 models, +3 shells>2019 (green) - +3 models, +4 shells>2020 (blue) - +5 new models, +13 shells>2021 (violet) - +3 models, +20 shells (including 3 for Evatchi)So that's 15 different models and 61 shell designs.
Models with multiple shells are
>V1 - 15 shells>V2 - 6 shells>Gudetama - 2 shells>Eevee - 2 shells>Pac-Man - 2 shells>Evatchi - 6 shells>Demon Slayer - 5 shells>Hello Kitty - 2 shells>Demon Slayer Hashira - 9 shells>Twistetchi - 7 shellsThe rest (both Usatama models, Usapiyo, Jordy, and Extellatchi) have 1 shell each.
It's starting to seem like going forward, they're going to put the Nano model towards franchises that can have lots of different shells. What do you think could be next? Power Rangers? Sailor Moon? Beastars?
