The Day Before Christmas

Take place three years after TRY3 defeat Gyze, an alternate ending for Vanguard G, Christmas is coming and there's a surprise installed for them. (mainly ChronoxTokoha, but there's an OC appearing and slightly KumixOC, featuring cameo appearances of Kamen Rider Build, Kaitou Sentai Lupinranger vs Keisatsu Sentai Patranger and Ultraman R/B)

I don't own Vanguard G and the others, they rightly belong to the owners (except my original character)
