A collection of my favorite characters, so there's no set world-building.
About
All characters have LED-style eyes and a mask-like lower face without a mouth or nose. They can transform into vehicle modes. Instead of changing color to show emotion, their LED eyes change shape (e.g., turning into half-moons when happy, drooping when sad, closing, or moving the pupils). — [Story Progression] The story follows a peaceful daily life spent with friends.
