Unkei (雲景) is an amanto carpenter. After Sakamoto Tatsuma breaks the Yorozuya house in Episode 33, he sends an apology mail. Inside this 'mail' Gintoki and the rest receive miniature space carpenters Unkei and his brother Kaikei. Identical to Kaikei other than the red skin. Unkei is the red half of twin "delivery" carpenters (carpenters for hire).
