About the studio
T-Rex is one of the more elusive names on this list, and honesty is the best policy here: there's no confirmed founding date on record, in English or Japanese. What is known is that T-Rex is a small Japanese studio working mostly on adult-oriented OVA anime, with credits appearing from the early 2000s onward. *Not every studio in the credits is chasing a Wikipedia page, and that's fine.* It doesn't have the sprawling franchise history of a Toei or a Sunrise, and its output has stayed firmly in a specific, niche corner of the industry rather than mainstream television anime. If more verifiable details about its founding or ownership ever surface, this profile is worth revisiting, but for now, T-Rex remains one of those smaller production credits that keeps the anime industry's less visible corners running without much fanfare or public documentation.
