The second form created for <Key> after the events of Clockwork Flower Pavane Chapter 2.
A miniature humanoid robot with an orange monitor. Notably, Aris (Maid) includes it as part of her official art (worn like a keychain on the broom handle).
Don't tag <key> (blue archive) alongside <key> (robot) (blue archive) unless both forms of Key are present in the image.
