In the Takagi Building, after you interrogate a member of the Eternal Sun he runs into the bathroom to distract Yasuke. He then asks Yasuke who would win in a fight between Captain America and Captain Japan. Yasuke says that there is no Captain Japan, that his name is Sunfire, and that Sunfire would probably win. Captain America is from the Captain America/Avengers comics and Sunfire is from the X-Men comics.
