Tsugumi Ohba is the credited writer behind Death Note, one of manga's most iconic series. Here's the thing though—basically nobody knows who Tsugumi Ohba actually is. The real identity and even gender remain a complete mystery, which has spawned endless fan theories over the years.

Some fans are pretty convinced that "Tsugumi Ohba" is just a pseudonym for Hiroshi Gamou, though nothing's ever been confirmed. The secrecy has only added to the legend.

What we do know is how Ohba works: apparently spending entire days hunched on a chair with knees pulled up, plotting out manga stories. Fans have noted the irony that this posture mirrors L's iconic pose from Death Note itself—the very series Ohba wrote. Whether that's intentional or just a funny coincidence, it's the kind of detail that's made the rounds in fan communities.
