Terror

Terror (@dog_tero) is a human-faced dog and the cat from Mogami's world's rival. He is ranked #1 on Reigen's list (along with Serizawa). Terror has learned how to write certain words, including "shithead", from Evelyn and the other Serizawa. Terror has also died in the hands of Evelyn, but was revived by the one and only Reigen Arataka.

Terror's owner is now unable to take care of him, and thus Serizawa has decided to take care of him instead.
