There was a sketch released on Himaruya's blog of 2P! America. It was never official and did not become canon as the sketch was not finalized. The sketch was under the 2P!files. One concept is him with his normal hair, wearing a tank top and dog tags. He's wearing military pants and combat boots, with gloved hands holding a rifle, and what appears to be a military jacket. The other sketch is him wearing a formal suit and cape while holding a book.
